WEDEMEYER, P.J.

Charles Barnes appeals from a judgment of conviction after a jury trial for violating § 941.29(2), STATS., felon in possession of a firearm.

Barnes claims two instances of trial court error entitling him to either a new trial or resentencing: (1) his constitutional right to a fair trial was violated when the trial court allowed the State to supply elements of the charged offense through the use of leading questions suggesting answers to a child witness; and (2) the trial court erroneously exercised its discretion in sentencing by penalizing him for exercising his right to a jury trial.

Because the trial court did not erroneously exercise its discretion regarding the manner in which the child witness was questioned and because the trial court did not erroneously exercise its sentencing discretion, we affirm.

I. BACKGROUND

On July 16, 1994, Milwaukee Police Officer Donald Brown was dispatched to the area of 30th and Clybourn Streets in the City of Milwaukee because of a report of a man with a gun. This report emanated from an observation made by ten-year-old Lourdes Correa. Brown interviewed Correa. She described the possessor of the gun as a bald-headed black male, six feet two inches tall, 200 pounds, wearing a tank top and beige pants. After interviewing Correa, Brown observed an individual who matched this description. The individual was identified as Barnes. Barnes was accompanied by a juvenile, Oliver Cathey. After brief questioning about the gun and a pat-down of Barnes, both men were released.

Shortly thereafter, Brown observed Cathey back in the same general area where he had originally been stopped. Suspicious of Cathey's activities, Brown stopped him intending to perform a pat-down for the missing gun. Cathey told Brown that Barnes had given him the gun the police officer was looking for but that Cathey had returned the gun to Barnes. Brown then searched the immediate area, located the gun, observed Barnes close by, and arrested both him and Cathey. At Barnes's trial the State presented three witnesses: Brown, Correa and Cathey. Cathey had already received one year juvenile probation for possessing a handgun as a result of this incident. The jury convicted Barnes of the charge and he now appeals.

II. DISCUSSION

A. Leading questions.

Barnes claims the trial court erred in allowing the State to direct leading questions to a ten-year-old child witness, which suggested answers crucial to proving the State's case. The trial court allowed the questions because of the age of the witness.

Standard of Review

Whether a challenged question is truly leading and suggestive, and whether the circumstances justify a leading and suggestive question is a matter of trial court judicial discretion. State v. Sarinske, 91 Wis.2d 14, 46, 280 N.W.2d 725, 740 (1979). We will not reverse a discretionary determination as long as the trial court considered the relevant facts, applied the proper law, and reached a rational determination. State v. Pittman, 174 Wis.2d 255, 268, 496 N.W.2d 74, 79-80, cert. denied, 510 U.S. 845 (1993).

Legal Framework

Although the practice of allowing leading or suggestive questions to be directed to child witnesses is well recognized, there are no reported cases in Wisconsin that directly address this very sensitive area of concern. Accordingly, we provide a brief look at the legal framework relevant to leading questions.

Section 906.11(3), STATS., provides: "Leading questions should not be used on the direct examination of a witness except as may be necessary to develop the witness's testimony." This provision is a subsection of § 906.11, STATS., entitled " Mode and order of interrogation and presentation," which also provides:

(1) Control by judge. The judge shall exercise reasonable control over the mode and order of interrogating witnesses and presenting evidence so as to (a) make the interrogation and presentation effective for the ascertainment of the truth, (b) avoid needless consumption of time, and (c) protect witnesses from harassment or undue embarrassment.

Generally speaking, three bases are given for discouraging the use of leading questions on direct examination:

[F]irst, that the witness is presumed to have a bias in favor of the party calling him; secondly, that the party calling a witness, knowing what that witness may prove, might by leading bring out only that portion of the witness' story favorable to his own case; and thirdly, that a witness intending to be entirely fair and honest might assent to a leading question which did not express his real meaning.

G. Stephen Denroche, Leading Questions, 6 CRIM L.Q. 21, 22 (1963).

The fourth circuit stated the concern behind leading questions even more succinctly in United States v. Durham, 319 F.2d 590, 592 (4th Cir. 1963), explaining that: "The evil to be avoided is that of supplying a false memory for the witness." See also 3 JACK B. WEINSTEIN Et Al., WEINSTEIN'S EVIDENCE ¶ 611-76-84 (1995). The suggestive nature of the interrogatory has no stock form. "The tenor of the desired reply can be suggested in any number of ways, as, for example, by the form of the question, by emphasis on certain words, by the tone of the questioner or his non-verbal conduct, or by the inclusion of facts still in controversy." 3 WEINSTEIN ET AL., ¶ 611-77, 78.

In spite of the amorphous form of the guarded-against "evil" usage of the leading question, it is not altogether forbidden under our statute, the Federal Rules § 611(c) or the Model Code of Evidence Rule 105(g). There are occasions when leading questions may be not only necessary, but desirable. Instances when leading questions have been allowed include: when the witness is immature, timid or frightened; when the testimony relates to introductory or undisputed matter; when the witness's recollection is exhausted; when the witness is in such a physical or mental condition that he or she ought to be spared the effort of responding in extended answers; or when the witness is called to disprove prior testimony of another witness. See 3 WEINSTEIN ET AL., ¶ 611-79, 80. Moreover, when § 906.11(3), STATS., is applied to a child witness, an exception to the undesirability of leading questions on direct examination has been historically recognized. Judicial Council Committee's Note, § 906.11(3), Wis. Rules of Evidence, 59 Wis.2d R191, Federal Rule of Evidence 611(c), Notes of Advisory Committee (1972); United States v. Castro-Romero, 964 F.2d 942, 943-44 (9th Cir. 1992). Thus, there exists a rationale for placing the application of § 906.11(3), STATS., in the discretionary authority of the trial court.

Analysis

Having reviewed the relevant legal framework, we now examine Barnes's claim to determine whether the trial court erred in allowing the State to ask leading questions of ten-year-old Correa. Barnes argues that the leading nature of these questions supplied the element of identification and that without that element, the State's case would have failed. We affirm the trial court for three reasons: (1) the trial court did not erroneously exercise its discretion in concluding that because of Correa's age, it would allow the leading questions; (2) the record demonstrates that Correa was a timid and frightened witness, and because of this (and her young age), the leading questions were necessary to develop her testimony; and (3) there is no evidence that the leading questions supplied a false memory.

From a form standpoint, it appears that defense counsel decided the State's questions were just too leading and suggestive and finally objected to the form of the questions. From a substantive standpoint, because of the lack of exactitude at the trial level, it is impossible to ascertain precisely what questions trial counsel felt were objectionable for the purposes of possible appeal. Thus, we could dispose of this issue by applying waiver, see § 901.03(1)(a), STATS., but eschew this approach to help enunciate and amplify the principals of § 906.11(3), STATS.

When defense counsel objected to the form of the questions, the trial court acknowledged the leading nature of the questions but overruled the objection because of Correa's age, stating that the methodology was "appropriate." The trial court's reasoning is consistent with the recognized exception of allowing leading questions during direct examination of a child witness, and hence was not an erroneous exercise of discretion. We acknowledge Barnes's concern that "infancy is not an open door to leading questions." Nevertheless, directing such questions to a child witness has become a well recognized exception to the prohibition on using leading questions during direct examination. See Castro-Romero, 964 F.2d at 943-44. The young age of the witness often makes it necessary to use leading questions in order to develop their testimony.

Although Correa's age was the only factor the trial court explicitly referred to in its ruling, we infer from the ruling, and the record as a whole, that the trial court based its decision on the fact that under the circumstances of the case, the leading questions were necessary in order to develop Correa's testimony. From a reading of the direct examination of Correa by the State, it is not unreasonable to conclude that the series of questions was used by the State to develop a child witness's testimony, rather than to supply a false memory.

In addition, it is undisputed that Correa was subpoenaed as a witness, but failed to appear resulting in the trial court issuing a bench warrant for her appearance. When she was brought to court, in response to the court's inquiry, she indicated that she was "a little" nervous. It is evident from the record that Correa was not a willing witness nor comfortable in her role in testifying as to what she observed. These additional facts, together with her young age, further support the trial court's ruling to allow the questions because they demonstrate that Correa was immature, timid and frightened.

In reviewing this issue, we note that the trial court is in the best position to evaluate the circumstances under which the ten-year-old was testifying. Barnes's trial counsel originally objected to certain questions relating to Correa's conversations with Officer Brown because she said she didn't remember what happen; yet with a little reasonable prodding by the trial court she was able to respond, and the State was able to develop observations made by Correa at the crime scene. When trial counsel again objected, this time for improper form, the trial court having had the opportunity to assess the circumstances under which Correa observed the criminal activity and her reluctance to appear in court, concluded that the exception to the rule of discouraging leading question should appropriately prevail.

Barnes further argues that allowing the leading questions improperly denied him substantial constitutional rights to confrontation, due process and fair trial. We are not persuaded. In State v. Williamson, 84 Wis.2d 370, 380, 267 N.W.2d 337, 342 (1978), our supreme court declared that the impropriety of allowing a leading question to stand has constitutional implications only if prejudicial. Based on the record, we conclude that allowing the leading questions did not prejudice Barnes. When the testimony of Cathey, Officer Brown's crime scene investigation testimony, and Correa's unobjected to testimony is viewed in its totality, even in the absence of the challenged leading questions, the jury verdict could not have been otherwise. Cathey's testimony alone was sufficient to secure a conviction. Cathey testified that Barnes had a gun on the date, time and place in question, and that Cathey took the gun from Barnes at Barnes's request to hide it so the police would not find it. Accordingly, we reject Barnes's claim.

B. Sentencing.

Barnes also claims that the trial court erroneously exercised its sentencing discretion when it sentenced him to an eighteen-month prison term, to be served consecutively to an unrelated prison term. Barnes asserts the trial court utilized an unreasonable or unjustifiable basis for the sentence it imposed when it considered the inconvenience two youthful witnesses and the system itself had been put through when he exercised his right to a jury trial. Thus, he claims he is entitled to resentencing without consideration of those factors. We conclude that the trial court properly exercised its sentencing discretion.

Standard of Review

Sentencing is a function of trial court discretion. State v. Harris, 119 Wis.2d 612, 622, 350 N.W.2d 633, 638 (1984). We are reluctant to interfere with a trial court's sentence because it has a great advantage in considering the relevant factors and the demeanor of the defendant. Id. There is a presumption that a trial court acted reasonably when sentencing. Id. Thus, to demonstrate an erroneous exercise of sentencing discretion, the defendant must show some unreasonable or unjustifiable basis in the record for the sentence imposed. State v. Echols, 175 Wis.2d 653, 681-82, 499 N.W.2d 631, 640, cert. denied, 114 S.Ct. 246 (1993).

Analysis

When sentencing, the trial court must consider the following three factors: (1) the gravity of the offense; (2) the character and rehabilitative needs of the offender; and (3) the need for protection of the public. State v. Sarabia, 118 Wis.2d 655, 673, 348 N.W.2d 527, 537 (1984). The significance of each factor, however, in the total sentencing process lies solely within the sentencing court's discretion as demonstrated by the record. State v. Patino, 177 Wis.2d 348, 385, 502 N.W.2d 601, 616 (Ct.App. 1993).

When considering the three primary factors, the sentencing court may also take into account: the vicious and aggravated nature of the crime; the past record of criminal offenses; any history of undesirable behavior patterns; the defendant's personality, character and social traits; the results of a presentence investigation; the degree of the defendant's culpability; the defendant's demeanor at trial; the defendant's age, educational background and employment record; the defendant's remorse, repentance and cooperativeness; the defendant's need for rehabilitative control; the right of the public; and the length of pretrial detention. State v. Borrell, 167 Wis.2d 749, 773-74, 482 N.W.2d 883, 892 (1992).

From our review of the sentencing transcript, we are satisfied that the trial court properly exercised its discretion in sentencing Barnes. The trial court noted the type of offense committed by Barnes involving a gun, a juvenile companion, and the consumption of alcohol. The occurrence itself took place in a neighborhood setting affecting a ten-year-old girl and her two young friends who observed the sequence of events. Lastly, the trial court observed that Barnes has "many unmet needs, both academic, social and personal referring specifically to his drug and alcoholic dependency and low IQ." Although Barnes claims he received a consecutive rather than a concurrent sentence for exercising his right to a jury trial, we reject this assertion because on two separate occasions during the sentencing, the trial court assured Barnes that his sentence would not be made more severe for electing to go to trial. In the context of the entire sentencing process, we find nothing to support Barnes's claim that the consecutive sentence imposed was unreasonable or unjustified. By the Court. — Judgment affirmed.
