bucket baby
n.— «I also hate to see bucket babies or unhappy children confined against their will to a stroller or carseat while a parent is oblivious or gives them a token “you’re okay” while she continues her adult stuff.» —“Re: do people not like holding their babies?” by Emily Roysdon Usenet: misc.kids.breastfeeding Sept. 11, 2003.
