Matilda likes to make sure everythings working down there, in fact she often gets a bit fascinated about it all... today in the shower she was washing herself and said "mummy, folds" and then "daddy no folds" so I guess she's just starting to discover these bits of life. I try not to make a big deal about it yet, and most of the times when she does it is at home when she's naked, I've never seen her do it away from home.
