I started potty training my 2yr7mo DD last weekend. the first day was as expected, accidents etc, then we managed to get some wees and even a poo in the potty! She went through a phase of lots of little leaks, but has now mastered control to the point that she doesn't seem to know how to start weeing. she refuses to wee in nappies, or pull ups, so I can't back off. She holds it in until she is sp desperate that she starts to wee, at which point we sit her on the potty and she will finish weeing there, unfortunately this is preceeded by about 2 hours of crying and jiggling up and down because she needs a wee. I'm worried that she will give herself a UTI (pretty certain that she doesn't have one at the moment), but also, she is waking in the night to wee, despite being in a nappy, and at that point is so tired she doesn't know what to do. I ended up puttin her in the bath at 3:30am to get her to wee. She will sit on the potty every couple of hours, but can't seem to start herself weeing. Any suggestions please, I am getting quite concerned .
