Where did Jesus spend His childhood?

After returning from Egypt, the Holy Family lived in Nazareth. Other than the fact of living there, both Matthew and Luke are silent on any details of His childhood.

Pope St. John Paul II taught,

The time [Jesus] spent in Nazareth, the greater part of his life, continues to be shrouded in deep silence. Very little information about it has been passed on to us by the Evangelists. However, if we aspire to a deeper understanding of Jesus' life and mission, we must draw close to the mystery of the Holy Family of Nazareth to observe and listen. (Angelus message, 30 December 2001)

Some apocryphal writings tell fantastic stories of Jesus childhood, especially miracles He is alleged to have done. The Church rejects them on account of their fabulous content, as well as their lack of apostolic and patristic support.
