so I'm exposing ds to the idea of using the potty, cuz he's interested, and i got him one of those baby bjorn potties, but... is it just me, or is it really really small? or does my boy have an extra large booty? he's supposed to be able to actually sit on it, right? cuz he can't. well, he sort of can, but then his little wiener is squeezed in there and it's just really uncomfortable. am i missing some really obvious aspect of the potty concept? gawd, this sounds like a dumb question.
