A lot of people are waiting until they are older to have children these days. And with advances in medical technology, you're still going to be okay even if you decide to wait until your 40s to have kids.

Personally, I never really thought about having kids or cared much. I like kids, but I don't know how to really interact with them. I'm scared too, mainly because I feel like I wouldn't know what to do with them. I don't want to be that crappy, clueless parent that everyone talks about.
