DS2, nearly 5, is obsessed with bottoms, willies, poo etc talk. It's beginning to worry me, largely I guess because our DS1 wasn't like this to the same extent.
Is this normal? I mean he offered to show DS1's friend (here for supper) his bottom, if he showed his back .
Deep down, I think a lot of it is probably normal, but I'm just worried by the sheer quantity of it. DH recently took him to a party and another dad said that his son had announced prior to the party that everyone there would have to show their bottoms! It could just be a nursery thing, I guess.
