OLSZEWSKI, Judge:
This is an appeal from a judgment of sentence entered after appellant’s conviction by jury of two counts of involuntary deviate sexual intercourse and three counts of corrupting the morals of a minor child. Appellant complains on appeal that: (1) the trial court erred in finding child witnesses competent to testify; (2) the trial court erred in permitting repeated re-examination of one child witness and counsel was ineffective for failing to object; (3) the trial court erred in denying appellant’s motions for a mistrial; (4) the trial court erred in permitting testimony as to prior consonant statements of two children and trial counsel was ineffective for failing to object; and (5) the trial court erred in not permitting evidence of prior inconsistent statements by two child witnesses.1 We find appellant’s claims to lack merit and, accordingly, we affirm the order of the trial court.
Evidence presented at trial established that between late 1985 and early 1986, appellant, while employed as a maintenance worker at a day school in Philadelphia, sexually molested three2 pre-school aged children. With each victim, appellant pretended to play various children’s games [192]*192which culminated in his penis being placed in each child’s mouth and/or rectal or genital area.
After conviction, post-trial motions were filed and denied. The trial court sentenced appellant to six to twenty-four years plus five years probation. This appeal followed.
Appellant first maintains that the trial court erred in finding the complainant children competent to testify. At the time of trial, the victims, R.J. E.J., and K.H., were aged five, five, and three and one-half, respectively. When evaluating the competency of children to testify, we are guided by the following principles:
A witness is presumed competent to testify unless proven otherwise. Commonwealth v. Riley, 458 Pa. 390, 326 A.2d 384 (1974). When a proposed witness is under fourteen years of age, however, there must be a searching judicial inquiry as to mental capacity. Commonwealth v. Short, 278 Pa.Super. 581, 420 A.2d 694 (1980). This inquiry will probe the capacity to communicate, observe and remember, and a consciousness of the duty to speak the truth in proportion to the witness’s chronological immaturity. Rosche v. McCoy, 397 Pa. 615, 156 A.2d 307 (1959)____ [T]he judge holds the superior opportunity to evaluate the competency of a proposed child witness____ Commonwealth v. Bailey, 322 Pa.Super. 249, 469 A.2d 604 (1983).
Commonwealth v. Stohr, 361 Pa.Super. 293, 522 A.2d 589 (1987).
Our Supreme Court has mandated that in evaluating competency, the trial court must be satisfied that the witness has:
“(1) such capacity to communicate, including as it does both an ability to understand questions and to frame express and intelligent answers; (2) mental capacity to observe the occurrence itself and the capacity of remembering what it is that [the witness] is called to testify about; and (3) a consciousness of the duty to speak the truth.”
[193]*193Rosche v. McCoy, 397 Pa. 615, 620, 156 A.2d 307, 310 (1959) (emphasis in original). See also Commonwealth v. Baker, 466 Pa. 479, 485, 353 A.2d 454, 457 (1976).
Commonwealth v. Hart, 501 Pa. 174, 177, 460 A.2d 745, 747 (1983). Determination of competency will not be disturbed on appeal absent a clear abuse of discretion. Id.
Instantly, the trial court made the following observations regarding the competency of the three children: each knew his/her name, age and where he/she went to school; each could distinguish colors; each articulated why he/she was in the courtroom; and each knew the difference between the truth and a lie and the consequences of telling a lie. In conclusion, the trial court stated:
Although the witnesses sometimes gave inconsistent answers and occasionally gave answers which could not possibly be correct, on the whole they demonstrated consistently that they knew the concept of truth, that they could understand the questions and that they could give intelligent, relevant answers. This was in contrast to the witness the Court found incompetent who, when asked a very concrete question about the weather that day, indicated that it was snowing (not a correct answer). Under the circumstances of this case, this Court did not commit error in finding witnesses [K.W.], [E.J.] and [R.J.] to be competent.
Opinion at 6.
The trial court’s inquiry, therefore, reflects a careful and guided determination as to whether each child was competent to testify. We find no abuse of discretion by the trial court.
Appellant next contends that the trial court erred in permitting the Commonwealth to re-question K.H. and in acting favorably towards the child. We note that appellant has preserved the issue of re-questioning the witness by objecting on the record and, therefore, we need not address the ineffectiveness alternative in this regard. Because appellant’s specific objection was that the question was “asked and answered,” however, appellant’s assertion on [194]*194appeal that the trial court’s behavior towards K.H. improperly influenced the jury is waived. See Commonwealth v. Berry, 355 Pa.Super. 243, 255-56, 513 A.2d 410, 416 (1986). Nonetheless, because appellant has cloaked this issue in an ineffectiveness assistance of counsel claim, we are constrained to address it. See infra.
Regarding the re-questioning of a witness, we adhere to the following principles:
The trial judges of this Commonwealth exercise broad powers while presiding at the trial of cases assigned to them. These powers include ruling on the admission or exclusion of evidence and controlling the scope of examination and cross-examination of witnesses. Such matters are committed to the sound discretion of the trial judge. Commonwealth v. Niemetz, 282 Pa.Super. 431, 422 A.2d 1369 (1980).
Commonwealth v. Pittman, 320 Pa.Super. 166, 172-73, 466 A.2d 1370, 1373 (1983).
In the instant case, the trial court admitted that the child was re-questioned. The court noted, however, that the requestioning was warranted because the child was tired. Opinion at 11. The court further observed that the child appeared intimidated by the jury. Id. The witness, nonetheless, indicated that she had something to tell the judge. In the interest of arriving at the truth, the trial court’s control of the examination was not an abuse of discretion.
Appellant’s counsel claims his own ineffectiveness for failing to preserve a challenge to the trial court’s favorable treatment of K.H. Our Supreme Court has recently mandated:
When appellate counsel asserts a claim of his or her own ineffective assistance of counsel on direct appeal, the case should be remanded for the appointment of new counsel except (1) where, it is clear from the record that counsel was ineffective or (2) where it is clear from the record that the ineffectiveness claim is meritless.
[195]*195Commonwealth v. McBee, 513 Pa. 255, 261, 520 A.2d 10, 13 (1986) (emphasis in original).3 We find that appellant’s claim is meritless and, therefore, need not remand for the appointment of new counsel.
When determining whether counsel rendered ineffective assistance, we must determine, first, whether the underlying claim has arguable merit. Only if the claim is determined to be of arguable merit do we inquire as to the reasonableness of counsel’s action or inaction. Finally, appellant must have been prejudiced by counsel’s performance such that the trial outcome would likely have been different. Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984); Commonwealth v. Griffin, 357 Pa.Super. 308, 515 A.2d 1382 (1986).
Instantly, counsel’s allegations concerning his performance do not surmount the arguable merit hurdle. There was simply no impropriety by the trial court to which counsel should have objected. Scrutiny of the record indicates that the trial court did not display its opinion as to the credibility of K.H. nor did the court question the witness in a way which reflects bias. As the court indicated, it was merely concerned with the comfort of the three and one-half year old victim:
In the instant case, this Court did not question the witness or in any way indicate an opinion as to the guilt or innocence of the defendant or the truth or untruth of witness’ testimony____ This Court merely stated to the witness, after the district attorney elicited that the witness was tired, “Would you like to go and have lunch now and come back later” to which the witness answered, “Yes” and the Court stated, “All right you can do that, dear, you can step down and go with your Grandmom”. This remark may show some appropriate solicitousness for the witness’ well being but certainly does not indicate [196]*196any opinion by the Court as to the truthfulness or untruthfulness of the witness’ testimony. Later on that day, after the witnss [sic] had been on the stand for some period of time, the witness indicated to the assistant district attorney that she was tired. After a sidebar conference requested by the district attorney the Court merely said, “[K.H.] you can step down now, you can go home with Daddy. All right?” It is difficult to see how this comment can be interpreted as expressing an opinion of the Court to either the witness or the jury concerning anything about the witness’ testimony. The defense also complains that the court displayed solicitude during the witness’ testimony for her, “fatigue, comfort and the number of people watching her” citing N.T. 193-4. As the Notes of Testimony indicate, this Court merely asked the witness if she would rather sit on her father’s lap and then asked defense counsel if he had any objection to the witness sitting on her father’s lap to which he replied, “No”. This Court also indicted to the witness that she should speak into the microphone and that if she did not want to look at the jury she could just look at counsel or at the Court and talk into the microphone. These actions and statements by the Court were totally within the bounds of propriety and did not prejudice the defendant in any way.
Opinion at 8-9.
In light of the foregoing, we find appellant’s ineffective assistance claim to be meritless.
Next, appellant maintains that the trial court erred in not granting appellant’s motions for mistrial made after two witnesses testified concerning the arrest of appellant for sexually assaulting D.R. First, appellant protests the following testimony of Officer Tufo elicited during the Commonwealth’s case in chief:
Q. And in regards to [D.R.], did you also show him photographs, including the photograph of the defendant? A. Yes, ma’am.
Q. And did you also take with you and use when you spoke to [D.R.] the anatomically correct dolls?
[197]*197A. Yes, ma’am, I did.
Q. Detective, as a result of that interview, did you obtain any arrest warrants?
A. Yes, ma’am.
Mr. Turner: Objection.
The Court: I’m going to sustain the objection and ask that the jury disregard that answer.
Ms. Muldrow: Now, Detective, as part of your investigation then you obtained warrants as far as [K.H.], as far as [R.J.] and as far as [E.J.], and as far as [D.R.]; is that correct?
The Court: Objection sustained. May I see counsel at sidebar, please.
Trial transcript at 400-401.
At a subsequent proceeding in chambers, the Commonwealth indicated that they did not have any substantive evidence regarding the D.R. charge. The trial court declared, therefore, that it would not permit testimony that an arrest warrant was obtained and that charges were brought on the basis of something done to D.R. The court then cautioned the jury:
Members of the jury, I have sustained defense counsel’s objection to the question asked by the Distric Attorney, and I am instructing you that you are to disregard anything that you may have heard about a warrant or [D.R.]. That’s not part of this case and you are to totally disregard that. And if you have anything in your head about that, put that out of your mind. You are not to be concerned with this in anything that you have to do with this case. If there is anyone that doesn’t understand what I just told them, please raise your hand and I will try to make it more clear. I see that no one raised their hand, therefore, everybody has understood my instructions.
Trial transcript at 406-407.
Second, appellant complains of comments made by D.R.’s mother who was called in rebuttal to testify that a teacher [198]*198at A.B. Day School had, asked her to watch a classroom while she left for a few minutes. When questioned about this event, however, D.R.’s mother unexpectedly mentioned that her son had been molested. During an immediate conference in chambers, both counsel stated that the Commonwealth had not intentionally elicited the comment. Trial transcript at 692. The court then instructed the jury to
... totally disregard the last witness and anything that she said. Her testimony had nothing to do with this case. It is to be totally disregarded by all of you. Just forget that she was ever called to the witness stand. Nothing that she said is relevant here.
Trial transcript at 698.
Appellant contends that the comments by Officer Tufo and D.R.’s mother were so prejudicial that the trial court should have granted a mistrial. When evaluating whether the introduction of irrelevant evidence requires a new trial, we are guided by the following principles:
Our review of the grant or denial of a new trial is limited to determining whether the trial court abused its discretion or committed an error of law. Commonwealth v. White, 482 Pa. 197, 393 A.2d 447 (1978).... As a general rule, evidence of crimes unrelated to the charge for which the defendant is being tried, is inadmissible.4 Commonwealth v. Martin, 479 Pa. 63, 387 A.2d 835 (1978); Commonwealth v. Turner, 454 Pa. 439, 311 A.2d 899 (1973). There is no per se rule that requires a new trial for a defendant every time there is reference to prior criminal activity. Commonwealth v. Heaton, 504 Pa. 297, 472 A.2d 1068 (1984). “[W]e have never ascribed to the view that all improper references to prior criminal activities necessarily require the award of a new trial as the only effective remedy.” Commonwealth v. Williams, 470 Pa. 172, 178, 368 A.2d 249, 252 (1977).... An immediate curative instruction to the jury may alleviate any harm to [199]*199the defendant that results from reference to prior criminal conduct, [citations omitted] ... “[W]hether the exposure of the jury to improper evidence can be cured by an instruction depends upon a consideration of all the circumstances.” Commonwealth v. Richardson, [496 Pa. 521, 526, 437 A.2d 1162, 1165 (1981) ].
There are exceptions to this general rule. [E]vidence of other crimes is admissible when it tends to prove (1) motive; (2) intent; (3) absence of mistake or accident; (4) a common scheme, plan or design embracing commission of two or more crimes so related to each other that proof of one tends to prove the others; or (5) to establish the identity of the person charged with the commission of the crime on trial____ Commonwealth v. Peterson, 453 Pa. 187, 197-198, 307 A.2d 264, 269 (1973).... [We determine that the instant situation does not fall into any of the enumerated exceptions].
Commonwealth v. Morris, 513 Pa. 169, 175-77, 519 A.2d 374, 377 (1986)
We have further mandated that two considerations are particularly pertinent in determining potential prejudice: (1) the nature of the reference; and (2) whether the testimony was intentionally elicited by the prosecutor. Commonwealth v. Satzberg, 358 Pa.Super. 39, 49, 516 A.2d 758, 762 (1986) citing Richardson, supra. In the present case, it is apparent that the comments were not intentionally elicited; in fact, the court discovered that the Commonwealth had cautioned D.R.’s mother not to mention the incident or arrest.5
Additionally, the trial court thoroughly and immediately instructed the jury that the statements had nothing to do with the case and should be disregarded. Appellant is entitled to a fair trial, not a perfect one. Morris, supra 513 Pa. at 178, 519 A.2d at 378, citing Bruton v. United States, [200]*200391 U.S. 123, 88 S.Ct. 1620, 20 L.Ed.2d 476 (1968). We have reviewed the circumstances and conclude that any prejudice to appellant because of the reference to the arrest was effectively neutralized by the cautionary instruction to the jury. The trial court did not abuse its discretion in denying the motion for a mistrial.
Appellant next challenges the introduction or prior consonant statements of two of the victims. First, appellant claims that the court erred in permitting RJ.’s mother to testify as to statements made by R.J. between four to eight hours after one incident. The trial court admitted the mother’s statements as res gestae under the excited utterance exception to the hearsay rule.
To qualify as an excited utterance, a statement must be:
“A spontaneous declaration by a person whose mind has been suddenly made subject to an overpowering emotion caused by some unexpected and shocking occurrence, which that person had just participated in or closely witnessed, and made in reference to some phase of that occurrence which he perceived, and this declaration must be made so near the occurrence both in time and place as to exclude the likelihood of having emanated in whole or in part from his reflective faculties.”
Commonwealth v. Stohr, supra 361 Pa.Super. at 297, 522 A.2d at 592, quoting Allen v. Mack, 345 Pa. 407, 410, 28 A.2d 783, 784 (1942).
A time lapse between an assault and the statement does not necessarily negate the indicia of reliability which underlies the res gestae rule. Commonwealth v. Bailey, 353 Pa.Super. 390, 510 A.2d 367 (1986) (plurality). The requirements of spontaneity is a question which turns on the circumstances of each case and is relaxed when the child declarant is the victim of a sexual assault. Commonwealth v. Stohr, supra 361 Pa.Super. at 298, 522 A.2d at 592. We noted in Stohr:
“Such a relaxation of the rule recognizes both the likelihood of a young child’s inability to comprehend ... the assault and the possibility of the child’s hesitancy to [201]*201discuss the matter for fear of incurring punishment.” Commonwealth v. Pronkoskie, [477 Pa. 132] at 142 n. 9, 383 A.2d [858] at 863 n. 9 [ (1978) ].
Id., 361 Pa.Superior Ct. at 298, 522 A.2d at 592.
Instantly, the trial court opined:
[T]he sexual attack on [R.J.] occurred sometime between the hours of 7:30 A.M. when he was dropped off at the A.B. Day School and 4:30 P.M. when he was picked up by his mother [A.J.]. She observed that he was visibly upset and had been crying. At that time, R.J. refused to discuss what was upsetting him. Later, at approximately 7:00 P.M. that evening he asked his mother if he could take a bath; a very unusual occurrence. Upon being asked why he wanted to do such an unusual thing, he replied, “because the bumble bee stung me.” His mother, thinking that a real bumble bee had stung him, continued to ask him questions about the sting. In answer to her questions, he indicated that he had been stung in the rectum. He kept insisting he wanted to take a bath because he was dirty. In response to questions about where it happened and what size the bumble bee was he indicated that it happened in the bathroom and that the bumble bee was, “tall, big like my daddy.” He also stated that the bumble bee stung him with his tail which he further indicated was the penis. As he spoke about the incident, he was visibly fearful and nervous.
Opinion at 15-16.
We have held that a six-hour delay is not enough to cast doubt on the spontaneous nature of the statement as res gestae. Commonwealth v. Norwalk, 160 Pa.Super. 88, 50 A.2d 115 (1946). As long as the statement was clearly a product of overpowering emotion caused by a traumatic and humiliating experience, an even greater delay would not preclude introduction. Bailey, supra. We find, therefore, that the statements by the victim were sufficiently reliable and were properly permitted as spontaneous declarations.6
[202]*202Appellant also complains of the testimony by Officer Tufo and the victims’ mothers as to other prior consonant statements of the victims. The record reflects that counsel’s request for a continuing objection as to such questions was denied and counsel failed to subsequently object to the challenged testimony. The issues are, therefore, not preserved for our review.
Counsel, however, resurrects the claims by alleging once again his own ineffectiveness. We proceed according to the principles discussed supra, and again find the ineffectiveness claim to be meritless.
A careful reading of the record and applicable case law indicates that the statements not objected to were admissible as prior consonant statements offered to negate the inference by appellant that the victims’ testimony was recently fabricated. Commonwealth v. Clark, 355 Pa.Super. 200, 512 A.2d 1282 (1986). We have stated that:
Prior declarations of a witness which are consistent with his present testimony may be admitted to corroborate his testimony at trial if impugned, expressly or impliedly, as the product of recent fabrication, particularly when improper influence of the witness is implicated. See Commonwealth v. Cruz, 489 Pa. 559, 414 A.2d 1032 (1980). Commonwealth v. Clark, 355 Pa.Super. 200, 512 A.2d 1282 (1986). As noted in Commonwealth v. Gore, 262 Pa.Super. 540, 550, 396 A.2d 1302, 1307 (1978), “it is not necessary that the impeachment be explicit, i.e., that an [203]*203actual allegation of recent fabrication be made, but only that a jury be able to reasonably infer that such is occurring.” See also Commonwealth v. Bailey, 322 Pa. Super. 249, 469 A.2d 604 (1983); Commonwealth v. Kjersgaard, 276 Pa.Super. 368, 419 A.2d 502 (1980).
Commonwealth v. Cain, 358 Pa.Super. 198, 201-02, 516 A.2d 1252, 1254 (1986).
An examination of the record indicates that while appellant did not expressly assert fabrication, the following line of questions implies fabrication:
Q. You love your mommy don’t you?
A. Yes.
Q. And you love your daddy, don’t you?
Q. And, [R.J.], when they tell you to do something you do it.
Trial transcript at 178. In addition, appellant’s counsel asked questions on cross-examination emphasizing that R.J. and E.J. had gone over their testimony numerous times before trial with the district attorney’s office.
These areas of inquiry could cause a jury to infer that the recollection of the young victims was influenced by family and conviction-oriented individuals. See Cain, supra, 358 Pa.Superior Ct. at 202, 516 A.2d at 1254. Hence, the testimony of the victim’s mothers and Officer Tufo relating what R.J. and E.J. had said was admissible to rebut an inference of fabrication. Therefore, appellant’s claim of ineffectiveness for a failure to object to such testimony is meritless.
Finally, appellant contends that the trial court erred in refusing to permit appellant to read to the jury testimony of two of the victims from preliminary hearings. Appellant alleges that he was denied the right to confront witnesses with alleged prior inconsistent statements.
Regarding R.J., appellant contends that various parts of the boy’s preliminary hearing testimony exemplified prior [204]*204inconsistent statements warranting admission for impeachment purposes. We have declared that:
[M]ere dissimilarities or omissions in prior statements, even when the statements are the verbatim words of the victim, do not suffice as impeaching evidence; the dissimilarities or omissions must be substantial enough to cast doubt on a witness’s testimony to be admissible as prior inconsistent statements. See Commonwealth v. Gee, 467 Pa. 123, 354 A.2d 875 (1976); In re Silverberg, 459 Pa. 107, 327 A.2d 106 (1974); Commonwealth v. Ryan, 253 Pa.Super. 92, 384 A.2d 1243 (1978); M. Greenberg & A. Bocchino, Pennsylvania Evidence 88 (1983); G. Lilly, An Introduction to the Law of Evidence § 83 at 303 (1978).
Commonwealth v. Bailey, 322 Pa.Super. 249, 263, 469 A.2d 604, 611 (1983).
A perusal of the preliminary hearing transcript indicates that the trial court correctly assessed the child’s negative answers therein as mere reluctance to testify rather than affirmative denials. We hold, accordingly, that the trial court did not err in refusing to permit the prior testimony.
Regarding the preliminary hearing testimony of E.J. which appellant sought to use for impeachment purposes, we first note that some of the testimony is relevant to the issue of competency only. Competency is a collateral issue and is not a matter for consideration by the jury at trial. Bailey, supra.
Appellant also sought to introduce prior statements which were omitted at trial. It is well settled that an omission is not the same as an inconsistency. Commonwealth v. Hammond, 308 Pa.Super. 139, 454 A.2d 60 (1982). The trial court properly exercised its discretion by not allowing cross-examination as to an omission. Id., 308 Pa.Superior Ct. at 148, 454 A.2d at 64. None of appellant’s remaining proffered preliminary hearing statements establish substantial inconsistencies such that they should have been permitted. Bailey, supra.
The judgment of sentence is affirmed.
