'Mummy, mums and girls have got tutties. Daddy has got a long tuttie, but girls and mums have got down ones.
Mummies have got up breasts and up nibbles, for feeding babies. Girls have got down breasts and nibbles, so they can only 'pretend feed' their dolls.
Daddies have got down breasts and five (?!) nibbles, so they can't feed babies or dolls.'
Later, when DH returned from work and started to change out of his suit.......
'Oh no mum, daddies have got 'up' breasts after all!'
PMSL, as DH really isn't overweight at all, but has suddenly taken up training again, bless him! It's not vanity on his part, but I think he was a little shocked by the lovely, innocent yet harsh truth often spoken by little people.
