DD2 was 2 in May: she's completely aware of when she wees and can even hold on to it for a while - but totally refuses to go on the potty or the kiddies' toilet seat. ie if she's running around naked and wants to do a wee, she demands to have a nappy on and gets quite upset. Any suggestion that maybe she should sit on the potty rather than have a nappy on is rejected out of hand. Do I let her deliberately wee in a nappy (which is kind of frustrating and I worry that it might become a habit) or do I try to push the potty more? (which makes me worry she'll get hung up about it). I don't mind how/when she gets trained as long as she's happy.
