Oh I hate that "good-baby" question too Krystie!! It really bothers me. I generally say "well there's no such thing as a bad baby is there?" It (hopefully) makes them stop and think about what they've just implied (probably unintentionally).

I read in another thread recently that up to 50% of babies don't sleep through the night regularly during the first year. So if people want to equate good with sleeping through, we should ask them if they did or didn't sleep through when they were a baby!
