Luke 1:57 - 80

In this passage, John the baptist is born, much to the joy of his parents and Elizabeth's relatives and neighbors. When asked the name of the child, she told them John. However since there were no "Johns" in the family, people were confused. So they asked Zechariah to write the child's name on a tablet, and he wrote "his name is John". At that moment, Zechariah was allowed to speak again, and he praises God for his redeeming strength of salvation for his people Israel. He also tells of how his newborn son will be called a prophet of the Most High, and will give "his people the knowledge of salvation through the forgiveness of their sins".

There is no mention of John's childhood after this... only that he grows up strong in the spirit and eventually lives in the Desert, before his public ministry begins.
