I was a feminist from a very young age - and decided that having kids would make me like all the grown up women I knew - shackled to their house, with no outside interests and no knowledge of the world outside. I especially noticed how most of the women I knew did not have any political awareness at all. I determined to not have kids so I would not turn out like that. I married fairly early (at 23). I still decided I didn't want to have kids until I was 28 or so. I wanted to have kids some day, and I could see that my husband would be a good father, but I was not financially ready to have kids. It was not in the "plan". Then I got pregnant. It wasn't planned. I was scared $hitless the first week or so. When I accepted that I was going to have this kid, and would give the best of myself to raising him/her, I really started looking forward to having the baby.
So, yeah, when I got pregnant!
