What was Jesus like as a baby?
Here's the answer:
Jesus was God from the moment He was born, but the Bible does not tell us much about him as a baby.
As a baby, Jesus may have cried just like any other human baby. Crying is not a sin (either as a baby or as an adult). For babies, crying is how they express their needs when they are unable to talk. The Bible says that Jesus grew up in "wisdom and stature" like other children (Luke 2:52), so we can safely assume He did not talk any earlier than other human babies. Jesus must have cried when He was lonely, hungry, sleepy, uncomfortable, or sick. It is not a sin to want your momma when you are a baby or even when you are older.
We don’t know exactly when the human part of Jesus, as a growing child, was able to clearly understand He was also God—to know and share the thoughts and truths of God. The Bible tells us that Jesus was found answering the questions of the teachers in the temple courts, when He was only twelve years old (Luke 2:46). So we can assume Jesus had a complete awareness of the "God" part of Him by this time. Maybe this awareness started when Jesus was much younger than twelve—we cannot say the exact time because the Bible does not say. But it is unlikely that Jesus thought like God when He was only a baby, because He had to develop His language (speaking and hearing) abilities just like any other human baby does.
Jesus never sinned. But he likely shared many of the experiences we all had when we are children—crying when He got hurt due to a fall, feeling sad when a friend moved away, feeling hungry when He was ready to eat. It is so amazing that God the Son (Jesus) became a human and experienced all of the difficulties of living in our world and in a body just like ours, so He could be our Savior if we believe He died on the cross for our sins!
"Jesus became wiser and stronger. He also became more and more pleasing to God and to people" (Luke 2:52).
"Now his parents went to Jerusalem every year at the Feast of the Passover. And when he was twelve years old, they went up according to custom. And when the feast was ended, as they were returning, the boy Jesus stayed behind in Jerusalem. His parents did not know it, but supposing him to be in the group they went a day's journey, but then they began to search for him among their relatives and acquaintances, and when they did not find him, they returned to Jerusalem, searching for him. After three days they found him in the temple, sitting among the teachers, listening to them and asking them questions. And all who heard him were amazed at his understanding and his answers" (Luke 2:41-47).
