I have been asked several times if there are any stories about Christ as a young child. The answer is yes, they exist in Gnostic writing's, below is one such story, it is found in what has become known as "The Infancy Gospel of Thomas" From the Apocryphal New Testament.
The term Apocrypha is used with various meanings, including "hidden", "esoteric", "spurious", and "Christian texts that are not canonical".
The word is originally Greek (ἀπόκρυφα) and means "those having been hidden away" Anyway with that brief introduction here's the story.
Now a certain teacher, Zacchaeus by name, came near unto Joseph and said unto him: Thou hast a wise child, and he hath understanding. Come, deliver him to me that he may learn letters. And I will teach him with the letters all knowledge and that he salute all the elders and honour them as grandfathers and fathers, and love them of his own years. And he told him all the letters from Alpha even to Omega clearly, with much questioning. But Jesus looked upon Zacchaeus the teacher and saith unto him: Thou that knowest not the Alpha according to its nature, how canst thou teach others the Beta? thou hypocrite, first, if thou knowest it, teach the Alpha, and then will we believe thee concerning the Beta. Then began he to confound the mouth of the teacher concerning the first letter, and he could not prevail to answer him. And in the hearing of many the young child saith to Zacchaeus: Hear, O teacher, the ordinance of the first letter and pay heed to this, how that it hath [what follows is really unintelligible in this and in all the parallel texts: a literal version would run something like this: how that it hath lines, and a middle mark, which thou seest, common to both, going apart; coming together, raised up on high, dancing (a corrupt word), of three signs, like in kind (a corrupt word), balanced, equal in measure]: thou hast the rules of the Alpha.
Now when Zacchaeus the teacher heard such and so many allegories of the first letter spoken by the young child, he was perplexed at his answer and his instruction being so great, and said to them that were there: Woe is me, wretch that I am, I am confounded: I have brought shame to myself by drawing to me this young child.Take him away, therefore I beseech thee, my brother Joseph: I cannot endure the severity of his look, I cannot once make clear my (or his) word. This young child is not earthly born: this is one that can tame even fire: be like this is one begotten before the making of the world. What belly bare this, what womb nurtured it? I know not. Woe is me, O my friend, he putteth me from my sense, I cannot follow his understanding. I have deceived myself, thrice wretched man that I am: I strove to get me a disciple and I am found to have a master. I think, O my friends, upon my shame, for that being old I have been overcome by a young child;- and I am even ready to faint and to die because of the boy, for I am not able at this present hour to look him in the face. And when all men say that I have been overcome by a little child, what have I to say? and what can I tell concerning the lines of the first letter whereof he spake to me? I am ignorant, O my friends, for neither beginning nor end of it (or him) do I know. Wherefore I beseech thee, my brother Joseph, take him away unto thine house: for he is somewhat great, whether god or angel or what I should call him, I know not.
There are many such stories written, as to their validity, this is between you and your creator.
