I got a baby picture from my crush. What can this mean?

Anonymous
One of my guy friends found out that I liked him and he said that he is crushing on me a little too. So far we text, hang out and stuff like that but we are not officially dating. Today completely out of the blue he sent me a picture of him when he was a baby. I saw the text very late at night. I don't want to wake him up so I didn't answer. Does anyone think that this could have any meaning?
