and aside from everything else wouldnt she get confused about having two bums? that just doesnt make sense. a friend of mine does this too, she was telling us the other day how her DD said she had a sore bum and so they put cream on it and then it took me about 5 minutes to figure out she was talking about her DDs vagina.

we used to call my DDs vagina a 'mimi' as that what my mum used to call mine. but one day at day care she was telling her teacher that her mimi was sore and they didnt know what she was on about. so from then on vagina it was. and you are right it felt uncomforable for the first few times but it is second nature now.
