DD1 has been showing signs of being ready to stop nappies from 17mths. Has consistently told us if she has had a wee or poo,if we take nappy off she holds it in until she can be out of sight to pee. She will be obviously pooing in nappy but will refuse to take it off and try the potty. She happily sits on the toilet but only if she can brush her teeth at the same time. The past 4 nights her bedtime nappy has been dry in the morning but she will not try to sit on potty or toilet to wee. She point blank refuses to sit on potty unless she is offered a chocolate button.In oct she was really good and over a couple of days she used potty to wee more than the floor then her asthma went bad and we were in hospital for a few days so stopped.Since then she just holds it in.. So where do I go from here??
