Did Jesus perform miracles as a child? I heard that there are some early books which tell of Jesus performing some miracles when he was a child. What are those books? And what are the miracles described in those books? 

Are descriptions of Jesus performing miracles as a child, before he began His ministry, acceptable according to the canonical Bible?
The Bible itself seems to indicate that Jesus performed no miracles until His ministry began.  Non-biblical sources may disagree, but they are non-biblical.

John 2 records to miracle at the wedding in Cana, where Jesus turns water into wine.  John completes the account with the following statement:


  This, the first of his signs, Jesus did at Cana in Galilee, and manifested his glory. And his disciples believed in him.  John 2:11 ESV


So, John records this as the first miracle.
