Hey, if Batgirl wants to spend her day scrutinizing her infant's facial expressions -- "is he pooping or just staring at a cracker crumb?" -- that's totally her choice. But I can't help but think it's a total misnomer to suggest that the baby is potty-trained. The parents are the ones watching for signals, making the mad potty dash, and wiping up afterwards. Until a kid is old enough to at least utter the word "potty" -- or, I don't know, crawl -- the parent is the one who's potty-trained.
I'll stick with diapers. I have enough to worry about without anyone pooping on the floor because I missed a scrunchy-face. What about you -- have you tried, or would you try, EC-ing?
