Other than Luke 2:41-52, the Bible does not tell us anything about Jesus’ youth. From this incident we do know certain things about Jesus’ childhood. First, He was the son of parents* who were devout in their religious observances. As required by their faith, Joseph and Mary made the yearly pilgrimage to Jerusalem for the Feast of the Passover. In addition, they brought their 12-year-old son to celebrate His first Feast in preparation for His bar mitzvah at age 13, when Jewish boys commemorate their passage into adulthood. Here we see a typical boy in a typical family of that day.
We see also in this story that Jesus’ lingering in the temple was neither mischievous nor disobedient, but a natural result of His knowledge that He must be about His Father’s business. That He was astonishing the temple teachers with His wisdom and knowledge speaks to His extraordinary abilities, while His listening and asking questions of His elders shows that He was utterly respectful, taking the role of a student as was fitting for a child of His age.
From this incident to His baptism at age 30, all we know of Jesus’ youth was that He left Jerusalem and returned to Nazareth with His parents and “was obedient to them” Luke 2:51. He fulfilled His duty to His earthly parents in submission to the 5th commandment, an essential part of the perfect obedience to the law of Moses which He rendered on our behalf. Beyond that, all we know is that “Jesus grew in wisdom and stature, and in favor with God and men” (Luke 2:52).
Evidently, this is all God determined that we needed to know. There are some extra-Biblical writings which contain stories of Jesus’ youth (the Gospel of Thomas, for example).

NOTE: Since books like the Gospel of Thomas are not included in the Bible there are all sorts of debate surrounding this information. I’ll be researching this book and others to decide what else might be included on the life of Jesus as a Child.
