At one point Nancy tells Doug that she's having "another baby". Over the course of the series, Nancy and Jeff have only one baby, Timmy. No mention is ever made of another baby.
Doug: What about the baby? She doesn't want the baby.
Kate: If I got rid of a baby every time I thought I didn't want it, we wouldn't have much of a family.
Buddy: I'm the only girl in my class who's not... grown.
Willie: Hey, look, if you're talking about your flat chest -- forget it... They'll grow, don't worry.
Buddy: I wasn't talking about a flat chest! I was talking about height.
