LABARGA, J.
*874Petitioners D.H. and L.H. ("the Twins"), by and through their maternal grandparents ("the Grandparents"), seek review of the decision of the Second District Court of Appeal in D.H. v. Adept Community Services, Inc. , 217 So.3d 1072 (Fla. 2d DCA 2017).1 The Twins allege Respondents Adept Community Services, Inc. ("Adept"), and B.E.A.R.R., Inc. ("B.E.A.R.R."), negligently failed to protect the Twins from suffering physical, mental, and emotional injuries at the hands of their mother ("the Mother"). 217 So.3d at 1076. The Circuit Court for the Sixth Judicial Circuit in and for Pinellas County held the Twins' claims were barred by the four-year statute of limitations applicable to negligence claims, and granted summary judgment for the Respondents. Id. at 1075. The Twins appealed to the Second District, which affirmed the trial court's ruling. Id. For the reasons explained below, we quash the decision of the Second District and remand for further proceedings.
Facts
Shortly after the Mother was born, she was diagnosed with noncongenital cerebral palsy and seizure disorder. Desiring to live on her own, she moved out of the Grandparents' home when she was twenty years old. The Mother hired Adept and B.E.A.R.R. to provide support services, including helping the Mother to hire a live-in aide to provide around-the-clock assistance.
The Mother became pregnant in late 2004, and in September 2005 she gave birth to the Twins. She had moved back into the Grandparents' home during her pregnancy but was determined to live on her own again after the Twins were born. To facilitate this, the Mother hired Adept and B.E.A.R.R. to provide support services as before. Worried that the Mother would not be able to safely care for and raise the Twins because of her disability, the Grandparents arranged a meeting of the support workers from Adept and B.E.A.R.R. during which the Grandparents discussed their concerns. The parties dispute what transpired at this meeting: The Twins allege that the Grandparents told the support workers, "If anything happens to these little boys, all of you in this room are responsible." The Twins further allege the support workers nodded and promised to "ensure there were eyes looking out for" the Twins. Adept and B.E.A.R.R., however, deny that their employees undertook any such obligation. On October 11, 2005, the Mother and the Twins moved into an apartment together with the live-in aide.
On April 11, 2006, the Mother fired the live-in aide after an argument over the air conditioning in their shared apartment. Later that day, pursuant to an anonymous complaint, a petition to shelter the Twins was filed with the circuit court and the sheriff's office removed them from the Mother's custody. The Twins were taken to the Grandparents' home the next day.
A dependency petition for the Twins was also filed on April 11, 2006, and the statewide Guardian Ad Litem Program ("GALP") was appointed to represent the Twins in the dependency case.2 The Twins *875were adjudicated dependent on May 16, 2006, and placed in the "temporary care, custody, and control" of the Grandparents. 217 So.3d at 1075 (quoting adjudication of dependency). Three days later, the Department of Children and Families completed a comprehensive health assessment for each Twin "noting developmental delays and anxiety problems due to abuse and neglect." Id. at 1076. On March 15, 2007, the Twins were diagnosed with sensory disorder, a condition attributed to their past abuse and neglect. On April 13, 2007, the protective supervision was terminated, the GALP was discharged, and the Grandparents were made the Twins' permanent guardians.
On November 22, 2010, the Grandparents filed a claim as the "next friends and permanent guardians" of the Twins against Adept and B.E.A.R.R. Id. (quoting complaint). The Twins alleged Adept and B.E.A.R.R. had negligently failed to prevent them from being injured by their Mother's maltreatment. Id. B.E.A.R.R. moved for summary judgment,3 contending the Grandparents could have sued on the Twins' behalf at any time after they learned the elements of the Twins' claims had been satisfied, and that the Grandparents learned this no later than May 2006. Id. Therefore, the Respondents argued, the Twins' claims were barred by the applicable four-year statute of limitations. Id. The Twins contended the Grandparents were unaware of any cognizable injury before receiving the Twins' sensory disorder diagnosis on March 15, 2007. The circuit court initially denied the motion, but granted it after Adept and B.E.A.R.R. moved for reconsideration. Id.
The Twins appealed to the Second District, arguing summary judgment was improper because the record did not conclusively establish the date on which the Grandparents knew or should have known of the Twins' injury. Id. at 1077. The Twins also argued the record did not establish whether the statute of limitations was tolled at any point before the Grandparents were appointed the Twins' permanent guardians. Id.
The Second District rejected the "knew or should have known" rule of accrual, concluding it was "an expression of the delayed discovery doctrine." 217 So.3d at 1078. The Second District reasoned that such a rule would be barred by our decision in Davis v. Monahan .4 See 217 So.3d at 1078. Absent an applicable statutory exception, the Second District concluded, a claim "accrues when the last element constituting the cause of action occurs." 217 So.3d at 1077 (quoting § 95.031(1), Fla. Stat. (2006) ). Therefore, the Second District held the Twins' claims accrued-and the statute of limitations began to run-at the time they suffered a cognizable injury, which could not have occurred after April 11, 2006, the date they were removed from the Mother's custody. Id. at 1078-79.
The Second District also addressed whether the statute of limitations was tolled between April 11, 2006-the latest date the Second District determined the Twins' claims could have accrued-and April 13, 2007, when the Grandparents were appointed the Twins' permanent guardians. Id. at 1082-84. Florida law tolls the statute of limitations for a minor's tort claim when the child lacks a parent, guardian, or guardian ad litem who is not adverse *876to the child and has not been adjudicated to be incapacitated. § 95.051(1)(h), Fla. Stat. (2006).5 The Twins argued their claims were based on the Mother's inability to care for them, and that her interests were therefore adverse to theirs both with respect to the Twins' tort claims and in light of the dependency case which was pending during that period. 217 So.3d at 1083. The Twins further contended the Grandparents were only temporary custodians of the Twins during the relevant period rather than permanent guardians with plenary powers. Id. Finally, the Twins argued that, although a guardian ad litem had been appointed for purposes of the dependency proceeding, that guardian ad litem did not know of the factual basis for their claims against Adept and B.E.A.R.R. Id.
The Second District held the guardian ad litem's lack of knowledge of the Twins' injury was irrelevant to the question of tolling because section 95.051(1)(h) does not allow for tolling on the basis that a parent, guardian, or guardian ad litem is unaware of a minor's injury. Id. To hold that such a lack of knowledge is a basis for tolling, the Second District reasoned, a court "would have to add the words 'or does not know of the minor's injuries' to the statutory list of circumstances that toll the limitations period." Id. The district court declined to perform this "policymaking function" which "belongs to a legislature." Id. The Second District explained that, absent certain exceptions not relevant to this case, the plain language of the tolling statute provides that "the limitations period on a minor's cause of action is not tolled when a guardian ad litem exists." Id. Because the Twins were represented by a guardian ad litem in their dependency case, the Second District held, the tolling provision did not apply and the Twins' claims were barred by the statute of limitations. Id. at 1084.
Then-Chief Judge Villanti concurred specially in the district court's decision, explaining that, although the Twins were represented by a guardian ad litem in the dependency case,
more is required to avoid the tolling statute than simply the existence of an entity called a "guardian ad litem." The guardian ad litem in this case was appointed by the dependency court to represent the best interests of the twins in the dependency case .... To hold that the mere existence of a guardian ad litem-even one wholly bereft of the legal authority necessary to bring the civil action in question-is sufficient to avoid the tolling statute is to elevate form over substance at the expense of the very persons the statute is intended to protect.
Id. (Villanti, C.J., concurring specially). Judge Villanti concluded it was fundamental error to grant summary judgment without resolving whether the guardian ad litem was empowered to sue on the Twins' behalf and whether a guardian ad litem not empowered to sue could nevertheless defeat the tolling statute. Id. Judge Villanti acknowledged, however, that the Twins did not argue on appeal that tolling was available on the basis that the guardian ad litem lacked authority to sue on their behalf. Id. at 1085. Therefore, Judge Villanti "reluctantly" concurred in the Second District's conclusion that this issue was abandoned. Id. ; see also 217 So.3d at 1083 n.5 (majority opinion, declining to address this "difficult question of first impression" because *877it was not properly raised and briefed on appeal).
The Twins sought discretionary review from this Court on the basis that the Second District's decision conflicts with Drake v. Island Community Church, Inc. , 462 So.2d 1142 (Fla. 3d DCA 1984) ; S.A.P. v. State Department of Health & Rehabilitative Services , 704 So.2d 583 (Fla. 1st DCA 1997) approved , 835 So.2d 1091 (Fla. 2002) ; and Doe No. 3 v. Nur-Ul-Islam Academy, Inc. , 217 So.3d 85 (Fla. 4th DCA 2017). We accepted jurisdiction and granted oral argument. Florida's statewide Guardian Ad Litem Program and Florida's Children First, Inc., filed amicus briefs in support of the Twins.
The Twins raise four issues for our review, one of which we find dispositive: The Twins argue that the statute of limitations was tolled because the guardian ad litem had no power to sue on their behalf, and that the fundamental error doctrine allows the Court to address this issue despite their failure to properly present it to the district court. As explained below, we conclude the Second District erred in determining the Twins' claims were not tolled pursuant to 95.051(1)(h), Florida Statutes (2006).
Standard of Review
"A trial court's ruling on a motion for summary judgment posing a pure question of law is subject to de novo review." Clay Elec. Co-op., Inc. v. Johnson , 873 So.2d 1182, 1185 (Fla. 2003). "The party moving for summary judgment bears the burden of establishing irrefutably that the nonmoving party cannot prevail." Bryson v. Branch Banking & Tr. Co. , 75 So.3d 783, 785 (Fla. 2d DCA 2011). The application of section 95.051(1)(h) to this case is a question of statutory interpretation, which we review de novo. Borden v. East-European Ins. Co. , 921 So.2d 587, 591 (Fla. 2006). This Court interprets statutes according to their plain and obvious meaning unless that interpretation leads to a result which is unreasonable or contrary to the intent of the Legislature. Daniels v. Fla. Dep't of Health , 898 So.2d 61, 64 (Fla. 2005).
Analysis
Subject to certain exceptions not relevant here, Florida law provides that a statute of limitations is tolled by "[t]he minority or previously adjudicated incapacity of the person entitled to sue during any period of time in which a parent, guardian, or guardian ad litem does not exist, has an interest adverse to the minor or incapacitated person, or is adjudicated to be incapacitated to sue." § 95.051(1)(h), Fla. Stat. (2006). Children ordinarily cannot sue on their own behalf. See Kingsley v. Kingsley , 623 So.2d 780, 783 (Fla. 5th DCA 1993) ("Courts historically have recognized that unemancipated minors do not have the legal capacity to initiate legal proceedings in their own names."). Instead, children's claims can only be brought by and through "a guardian or other like fiduciary," or in the absence of any such representative "by next friend or by a guardian ad litem." Fla. R. Civ. P. 1.210(b). By tolling the statute of limitations during any period in which a child lacks a person who has a duty to act in the best interests of that child, section 95.051(1)(h) protects children from the danger that their claims will be time-barred before they can be brought.
In terms of the present case, this subsection tolls the statute of limitations during any period the Twins lacked a parent, guardian, or guardian ad litem; or during any period where those persons had an interest adverse to the Twins. The parties do not dispute that the Mother, as the person who maltreated the Twins, had an interest adverse to the Twins with respect to the present case. Therefore, the first *878requirement for tolling under section 95.051(1)(h) is satisfied: there was a period of time-from the time the Twins were first injured by the Mother's maltreatment until the present day-when the Twins lacked a parent whose interests were not adverse to their own with respect to their claims in this case.6 Because the existence of any one of the three classes of individual named in the statute is sufficient to defeat tolling, we must also examine whether there was any period of time during which the Twins lacked a guardian or guardian ad litem who was competent to sue and had no adverse interest.
I. Guardian
In order for statutory tolling to apply to a minor's claim, Florida law requires that there be a "period of time in which a ... guardian ... does not exist, has an interest adverse to the minor ... or is adjudicated to be incapacitated to sue." § 95.051(1)(h), Fla. Stat. (2006). Guardianships "are governed by a comprehensive statutory code and set of procedural rules." Hayes v. Guardianship of Thompson , 952 So.2d 498, 505 (Fla. 2006).7 Florida guardianship law defines "guardian" as "a person who has been appointed by the court to act on behalf of a ward's person or property, or both." § 744.102(9), Fla. Stat. (2006).8 The statute also distinguishes between a "Limited guardian," whose powers are limited to those specifically designated by court order, id. § 744.102(9)(a), and a "Plenary guardian," who exercises "all delegable rights and powers of the ward." Id. § 744.102(9)(b). Guardians are appointed by court order, and that order must not only state whether the guardianship is plenary or limited but also "the specific powers and duties of the guardian." § 744.344(1), Fla. Stat. (2006).
The record demonstrates that the order placing the Twins in the Grandparents' temporary custody did not create a guardianship. Instead, it temporarily placed the dependent Twins in the Grandparents' custody to ensure they would be well cared for until the court determined what further action was appropriate. The court's order states, "The children shall be placed in the temporary care, custody, and control of [the Grandparents]," requires the Mother to pay child support to the Grandparents, and gives the Grandparents "the right to authorize any necessary and emergency medical treatment and ordinary medical, dental, psychiatric and psychological care for the [Twins]." It does not authorize the Grandparents to exercise *879any other powers with respect to the Twins and refers to the Grandparents as "custodians," not guardians; nor does it refer to the many substantive or procedural aspects of Florida guardianship law. We therefore conclude the Twins lacked a guardian within the meaning of section 95.051(1)(h), Florida Statutes (2006), until the Grandparents were appointed as their permanent guardians on April 13, 2007.
II. Guardian Ad Litem
A. Interpreting § 95.051(1)(h), Fla. Stat. (2006)
The third and final element to statutory tolling of a child's claim requires that there be "a period of time in which a ... guardian ad litem does not exist, has an interest adverse to the minor ... or is adjudicated to be incapacitated to sue." § 95.051(1)(h), Fla. Stat. (2006). Guardians ad litem are "appointed by the court to represent the best interests of a child in a proceeding as provided for by law." § 39.820(1), Fla. Stat. (2006). "The guardian ad litem serves as the child's representative in court to represent the child's best interest." C.M. v. Dep't of Children & Family Servs. , 854 So.2d 777, 779 (Fla. 4th DCA 2003). When a child is a party to a legal action and lacks a qualified "representative, such as a guardian or other like fiduciary," the court in which that action is proceeding "shall appoint a guardian ad litem." Fla. R. Civ. P. 1.210(b).9 The suffix "ad litem" is a Latin phrase meaning "for the suit" or "for purposes of the suit." Ad litem , Black's Law Dictionary (9th ed. 2009). Florida law defines "guardian ad litem" in greater detail as "a person who is appointed by the court ... in which a particular legal matter is pending to represent a ward in that proceeding ." § 744.102(10), Fla. Stat. (2006) (emphasis added).
These definitions demonstrate that the term "guardian ad litem" has significance only within the context of the particular case in which the guardian ad litem is appointed as the representative of a child. As a simple linguistic matter, therefore, a statute referring to a "guardian ad litem" inherently refers to a specific lawsuit in which that guardian ad litem is acting, and does not refer to other matters in which the guardian ad litem is not representing the child in question.
Having identified the plain and obvious meaning of the term "guardian ad litem," we must now determine whether giving that meaning to the term as used in section 95.051(1)(h) would lead to a result which is unreasonable or contrary to the Legislature's intent. See Daniels , 898 So.2d at 64. "Indisputably, Florida's public policy manifests a strong intent to protect children from harm." Applegate v. Cable Water Ski, L.C. , 974 So.2d 1112, 1114 (Fla. 5th DCA 2008). "[O]ur laws have consistently reflected and recognized the very special and unique position of children" as being in many ways more vulnerable than adults. N. Fla. Women's Health & Counseling Servs., Inc. v. State , 866 So.2d 612, 661 (Fla. 2003) (Lewis, J., concurring in result only). In providing for the tolling of children's causes of action, it is clear the Legislature intended to increase procedural protections for children in situations where a child's inability to sue would likely lead to harm. It is difficult to imagine what *880other purpose section 95.051(1)(h) could possibly serve.
Given the obvious meaning of the term "guardian ad litem" as a representative appointed for a particular legal proceeding, and given the Legislature's well-evidenced intention to provide broad protection for children, we cannot read section 95.051(1)(h) to prohibit tolling of a child's claim when that child is not represented by a guardian ad litem in the proceeding in which the claim to be tolled is being litigated, merely because the child happens to be represented by a guardian ad litem in a different proceeding. Such a result would be unreasonable and contrary to the clear intent of the Legislature. Instead, we conclude that "guardian ad litem" as used in section 95.051(1)(h), Florida Statutes (2006), means a guardian ad litem appointed to represent the child in the particular proceeding in which the claim to be tolled is brought.
Applying this interpretation of section 95.051(1)(h) to the present case, we conclude the Twins lacked a "guardian ad litem" within the meaning of that statute. Although the Twins were represented by a guardian ad litem in the dependency proceeding from its inception until April 13, 2007, the Twins were never represented by a guardian ad litem in the case at bar. Therefore, the third requirement for statutory tolling under section 95.051(1)(h) is satisfied.
B. Issue Preservation
The Second District held section 95.051(1)(h) did not toll the Twins' claims because the Twins were represented by a guardian ad litem in the separate dependency proceeding. 217 So.3d at 1083. The Second District rejected the Twins' argument that the guardian ad litem did not know of the factual basis for the Twins' negligence claims, concluding that, based on the plain language of section 95.051(1)(h), the guardian ad litem's knowledge was irrelevant. Id. The Second District declined to address whether "the term 'guardian ad litem' in section 95.051(1)(h) means only a guardian ad litem legally authorized to file suit on the minor's behalf" because the Twins did not raise that argument on appeal. Id. at 1083 n.5. In his specially concurring opinion, then-Chief Judge Villanti did address this issue, but nevertheless concluded it was beyond the scope of the district court's review because it had not been raised. Id. at 1084-85 (Villanti, C.J., concurring specially).
A trial court's ruling is treated as correct except insofar as an appellant raises claims of error. Doe v. Baptist Primary Care, Inc. , 177 So.3d 669, 673 (Fla. 1st DCA 2015). "[P]oints covered by a decree of the trial court will not be considered by an appellate court unless they are properly raised and discussed in the briefs." City of Miami v. Steckloff , 111 So.2d 446, 447 (Fla. 1959). Claims of error not raised by an appellant in its initial brief are deemed abandoned. See Anheuser-Busch Cos. v. Staples , 125 So.3d 309, 312 (Fla. 1st DCA 2013). Even though an issue has been abandoned, an appellate court may nonetheless address that issue if it involves the court's "jurisdiction or other issues raising obvious fundamental errors." All. for Conservation of Nat. Res. in Pinellas Cty. v. Furen , 122 So.2d 51, 65 (Fla. 2d DCA 1960). Fundamental errors are those which go "to the foundation of the case or ... to the merits of the cause of action." Sanford v. Rubin , 237 So.2d 134, 137 (Fla. 1970). It is therefore possible, in very rare instances, to overcome certain procedural bars. In the present case, the district court declined to address whether the guardian ad litem's ability or inability to sue on the Twins' behalf had any effect *881on the applicability of section 95.051(1)(h). 217 So.3d at 1083 n.5. The Twins argue the trial court committed fundamental error by granting summary judgment without addressing the guardian ad litem's power to sue, and that the Second District should have ruled on the issue. They therefore ask this Court to overlook their failure to raise this issue below and to rule on the merits of their argument.
We conclude it is not necessary to reach this issue. Although the Twins did not raise this particular rationale for statutory tolling before the Second District, they nevertheless argued the applicability of section 95.051(1)(h), and the Second District ruled on the merits that section 95.051(1)(h) did not apply, in part because the Twins were represented by a guardian ad litem in the dependency proceeding. Id. at 1083. Accordingly, our decision today is concerned only with the fact that no guardian ad litem was appointed to represent the Twins in the case to which the tolling statute relates. This issue was adequately preserved and addressed on its merits by the Second District, and we may therefore reach it. See Savoie v. State , 422 So.2d 308, 312 (Fla. 1982) ("[O]nce this Court has jurisdiction of a cause, it has jurisdiction to consider all issues appropriately raised in the appellate process ... when these other issues have been properly briefed and argued and are dispositive of the case.").
Furthermore, as we have explained above, the phrase "guardian ad litem" in section 95.051(1)(h) refers only to a guardian ad litem appointed for the case in which the claim to be tolled is brought. Because no guardian ad litem was appointed in this case, determining the effect of the guardian ad litem's authority to sue on the tolling statute would require this Court to speculate about the powers of a hypothetical guardian ad litem who might have been appointed in this matter, but who was not in fact appointed, and about the effect those powers might have had upon our interpretation of section 95.051(1)(h). We decline to address the entirely separate issue of whether a guardian ad litem entitled to sue on the Twins' behalf would avoid the tolling statute. See D.H. , 217 So.3d at 1083 n.5 (declining to address this "difficult question of first impression").
III. Timeliness
As explained above, there were periods of time where the Twins lacked either a parent, guardian, or guardian ad litem, respectively, whose interests were not adverse to theirs and who had not been adjudicated as incapacitated to sue. Cf. § 95.051(1)(h), Fla. Stat. (2006). Because the existence of a representative for the child in any one of those categories is sufficient to avoid the tolling statute for the duration of such representation, we must now determine if there was any period of time during which those vacancies overlapped.
It is clear from the record that the Twins lacked a qualifying parent at all times during the events to which this case relates. As we have explained, the Twins also lacked a guardian within the meaning of section 95.051(1)(h) until the Grandparents were appointed their permanent guardians on April 13, 2007. Additionally, the Twins were not represented by a guardian ad litem in these proceedings at any time. Accordingly, we hold the applicable statute of limitations was tolled pursuant to section 95.051(1)(h), Florida Statutes (2006), at all times prior to April 13, 2007, when the Grandparents were appointed as the Twins' permanent guardians.
The statute of limitations applicable to the Twins' claims provides a four-year filing window. § 95.11(3)(a), Fla. Stat. (2006) (providing that causes of action "founded on negligence" must commence within four *882years).10 Because the statute of limitations was tolled at all times prior to April 13, 2007, the Twins were required to bring their claims within four years of that date in order for the claims to be considered timely. The complaint in the present case was filed on November 22, 2010, approximately five months before the limitations period expired. Therefore, the Twins' claims presented in this case were not barred by the statute of limitations.
IV. Other Issues on Review
Because the statute of limitations applicable to the Twins' claim was tolled at all times prior to April 13, 2007, we need not determine when those claims accrued. The Twins' claims are timely irrespective of when they accrued, and a determination with respect to that issue would have no impact on the dispositive question before this Court. The issue of accrual is therefore moot. See Godwin v. State , 593 So.2d 211, 212 (Fla. 1992) ("An issue is moot when the controversy has been so fully resolved that a judicial determination can have no actual effect."). The same is true with respect to the other issues raised on review. We therefore decline to address these issues.
Conclusion
We conclude the statute of limitations applicable to the Twins' claims was tolled pursuant to section 95.051(1)(h), Florida Statutes (2006), at all times prior to the Grandparents being appointed as the Twins' permanent guardians on April 13, 2007. We therefore hold the statute of limitations did not bar the Twins' claims in this case and that the Second District erred when it affirmed the trial court's order granting summary judgment on that basis. Because our decision today renders the remaining issues on review moot, we decline to address those issues. Accordingly, we hereby quash the decision of the Second District Court of Appeal and remand to that court for further proceedings consistent with this decision.
It is so ordered.
