I can't stand babies. They do nothing but eat and poop and cry. They have no personalities, and they're boring. Once they are able to move around themselves, and react to the environment, however, they become awesome. I'd say I like kids that are between 9 months and 5 years old. They have personalities, but haven't become jerks like older kids and adults have. (yeah, I'm lumping myself in this too)
So no, I don't think it's odd at all that people don't like babies. I'm a girl, btw, and I'm 30 years old. My boyfriend actually wants a kid more than me, and I think that's just because he wants someone to be able to play with in games that I don't particularly like.
