What do your kids call their genitals?

[BellissimoGecko]

Not a troll, honest! I'm editing a book aimed at kids aged 3-6 about bodies, and the author has suggested using 'fanny'.

I never referred to DD's bits as a fanny! But I didn't use vulva either... what do you/your dc that age call their bits?!

Tiddle, todger, bits, privates they know the real names obviously but they have nicknames

My six year old DD has a foo-foo. My 4 year old son has a winky.

Before the mumsnet police jump on me, they do know it’s vulva and penis but prefer to use these names.

My point was to ask about where the book might be published (audience) as in this particular case it might be relevant. I'm an editor too.
