Wow.....to tell you the truth, I'm always just assumed that I'd have children. It's something where I've never given it serious thought......right now, I know that I definitely do not want children though!!! My fiance and I are having enough of a time getting our own lives in order to bring another life into the mix!
If I were unable to have children, adoption is definitely an option though. It would probably be an older child because it just sucks that so many children out there are 13/14 and stuck in the foster care system and cannot find homes.
Taking care of one's body is something to consider when having a child. When I was in high school and had bulimia, I really didn't care that it affects your reproductive organs. Now that I'm older, it kind of worries me that I might have screwed up my body for a completely stupid reason.
