Ugh, my 8yo, too. So far, I've been trying to roll with the punches, and dreading the actual teen years.

Mine has started wearing a cami top under her shirt every day; she likes the ones Target carries, with bra-style straps. It's not clear to me if she's wearing them as bras, since she also will go out of the house wearing just a cami and short-shorts.

She didn't have any toys on her Christmas list last year, or any so far this year, either. Just electronics / clothes / makeup / jewelry.
