Jesus: The Egypt Years

Jesus the Egypt years, follows the life of Jesus Christ when he was in Egypt as a baby.  He was in Egypt for three and half years along with Mary his mother and Joseph. We know that Joseph was told by an angel to take the baby and his mother and flee to Egypt to avoid Herod's massacre. But that's just the beginning because in Jesus the Egypt years, we get to know that king Herod chase after them even when they get into Egypt. We watch the holy family go through Egypt cities, hiding in caves in order to avoid Herod's spies.
While they feed on what God provide for them to eat. For these three and half years, baby Jesus is growing up and we see him take his first step. We watch him say his first word and listen to his understanding of God at these tender age. With the first three and half years of baby Jesus's life spent running from one Egypt city to another with his mother and Joseph.  How did this not affect his thinking as a baby growing up? And how did they survived these years?
