He hasn't told me about his daughter yet?

Well I've been talking to this guy for about a week and he's really sweet. We went on a date last night and things went great! He seems like a great guy and we click so well. He told me he feels like he can be himself with me, and that he's comfortable with me. The only thing.. Well I found him on Facebook and as his cover picture, there was a newborn. I thought it could be a sister, but nope, the comments say congrats and beautiful daughter. This isn't a deal breaker for me, as I can see that the baby stays with mom and he probably keeps his distance from his ex. He just hasn't said anything to me. And I'm not sure what that means?

Is he scared?
