The bit about the pole dancing set being removed from Toys and Games made me laugh.
I have 2 girls and the solution is not to buy the bra - my 12 year old still wears a vest.
However, there were girls at primary school with padded bras. I remember La Redoute selling thongs for 7 year olds - my kids wouldn't have worn them - in fact they wouldn't wear them now. Too uncomfortable.
