We attended a music class at a toy's store this morning. There was a 3-4 year old girl there wearing a flouncy skirt....with no underpants. It was quite obvious when she rolled on the floor and kicked her legs over her head. Her dad was with her. I live in a pretty "free" town, but really? You don't force your kid to wear underpants even under protest? I was pretty creeped out.
