Our daughter has a fascination with belly buttons. She can find her own and anyone else's upon request, and likes the giving and receiving of raspberries. She has a bad habit of randomly lifting my shirt so that she can poke me in the belly and give me a raspberry. That wouldn't be so bad except that she will do it in public, and my belly and the public are never supposed to meet. She also gets very frustrated if she's wearing a body suit that she can't lift to see her own belly button.
Yesterday when I picked her up from daycare, one of the teachers asked if we'd every had any "trouble" with her outfit--a bright red jumpsuit with Winnie the Pooh on the front (who she was able to name that morning while pointing to her outfit). It turns out that she knows how to undo the snaps all along the front of the jumpsuit so that she can see her belly. She was unsnapping herself all day, unless she had her jacket covering it.
Oh well, at least one female in the family won't be afraid to wear a bikini in public.
