Like most here I don't hate them, but I don't like them either. It's such a bare bones lifestate you feed them, rock them and change them, that's it. Nothing is customisable about them and it misses out on some of the most common aspects of caring for a baby. Not being able to take them out is a bummer but in Sims 3 when we were able to I'd rather leave the kid at home cause it creeped me out (it squirmed alot in the pram kinda a fish out of water). Sims 2 probably had the best babies but it's just sad that it gets largely ignored.
