While i was at nursery picking my kids up the other day, the teacher was offering out some sweets that they'd been given, and I politely declined, only for my 3 yr old to shout at the top of her voice "Mummy's trying to lose her big fat tummy, so she can't have sweeties or she'll get big and fatter"
On a plus side, my 5 yr old told someone in a shop the other day "mummy has lost some of her tummy"
