It's driving me mad!
I have an 8 year old daughter. Every other word seems to be poo, with some willies, bum and wee thrown in for good measure.
Drawing willies on everything is highly hilarious apparently 
She's currently singing Last Christmas with alternative lyrics - 'last Christmas I went for a poo.....' etc
I don't mind a little bit but it's getting beyond a joke now. Fortunately she doesn't do it at school, these delightful conversations seem to be reserved for home, but still, I would like to have a conversation with her that doesn't include the word willy, poo or bum (or go out in the car without her drawing willies on the steamed up windows)
I ignore it, I tell her off, I refuse to engage in her conversation until she repeats it without the offending words, I even resorted to a sticker chart if she managed to get through a day without the toilet talk but nothing
Will it pass? Her older sister never really did toilet talk
