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.
This little child Jesus when he was five years old was playing at the ford of a brook: and he gathered together the waters that flowed there into pools, and made them straightway clean, and commanded them by his word alone. And having made soft clay, he fashioned thereof twelve sparrows. And it was the Sabbath when he did these things (or made them). And there were also many other little children playing with him.
And a certain Jew when he saw what Jesus did, playing upon the Sabbath day, departed straightway and told his father Joseph: Lo, thy child is at the brook, and he hath taken clay and fashioned twelve little birds, and hath polluted the Sabbath day. And Joseph came to the place and saw: and cried out to him, saying: Wherefore doest thou these things on the Sabbath, which it is not lawful to do? But Jesus clapped his hands together and cried out to the sparrows and said to them: Go! and the sparrows took their flight and went away chirping.
There are many such stories written, as to their validity, this is between you and your creator.
