I dislike babies but I like kids, in general. Good ones.
Children are little people, and they tend to be a lot smarter than we give them credit for, so I usually treat them like people. In general this means children like me. Plus I like toys and cartoons and video games, so we actually have stuff in common. I had to hang with my aunts 9 and 6 year old boys and we played Wii and watched Adventuretime. Not so bad.
I remember being a child very well, and I recognize that I have the opportunity, in every interaction, to influence children in a way that can help their development into decent adults. I try to take that responsibility semi-seriously.
That said I tend to hate children in public because they are poorly behaved, resultant of their upbringing. Still, I dislike parents much more than I dislike children. I also like blowing a six year old's mind by asking what they're playing on their DS and being like "Oh, Scribblenauts? Type in CTHULHU."
EDIT: I think the intro sequence to "Idiocracy" explains why it's important for smart people to have children, though. It's worth the financial hit, assuming you can raise them properly, to save the world from morons.
