Dd is 2.9 years old. She has been wearing knickers for six weeks and is still having accidents and not always attempting to take herself to toilet. About three weeks ago I tried to put a nappy on and eventually got one on, which twenty minutes later she took off saying she doesn't wear them anymore. She refused to wear a nappy for naps or night time about 5 weeks ago and just doesn't wee when sleeping or at night in general. She will ask to do a poo most of the time or does one when I sit her on after some accidents, so I did think some of them may be linked to this. What would you do?
