What would you do if you found out a person you were digging on had a kid?

I’m 20, and I’m in the midst of getting to know this one guy (who’s 28). He’s been really honest about everything (I don’t think he’s the type of guy to hide anything). But I found out that he has a kid. He had her when he was really young and stupid (you know that whole story). She lives with her mom since she’s more financially stable than he is. . . . I think she’s maybe 5 now? I guess my question is. . .would that be a deal breaker? I don’t really know how to handle this. I’m thinking of just being friends since a kid. . .well, is a rather large part of a persons life, and I for one am no where near being able to have to worry about that.
