Whether you've chosen to have children or live child-free, how and when did you (or will you) reach this decision? If you're in a relationship, did you (or will you) decide separately or together?
I'm not sure how or when really, as far as I could remember I've always wanted kids at some point. Always adopted though, never through pregnancy. This is in part to a combination of a) being adopted and b) thinking that pregnancy looks rough as hell.
Also, marriage was never factor in when I wanted to have kids, not really. It wasn't until a couple years ago when I realized it was probably odd to want to have kids without getting married, or even just having a long term partner, first. This is mostly in part to being raised by single mom most of my life.
As for why I want to have kids in general, it's hard to specifically pinpoint. I like kids, and I think I'd be a good parent when I'm older. Also, there seems so much love and satisfaction in raising a child. It's difficult to really put into words.
I want to have a solid career and housing situation when I apply for a kid. As for being in a relationship, if I'm in a relationship, I'd hope they would want kids too and that we could plan together, but I won't make them stay with me if they don't want to raise a child. I'm not sure if I'd be willing to give up the chance of having a kid to stay with my partner. But I don't feel like I'd need a partner to raise a child, but it would help...
As for right now I'm only in high school, I'm not planning to worry about it too much.
