My DD has been out of night nappies since she started using the toilet full stop. I tried putting one on her but she would get upset and take it off. She is 2yrs 5months now and has been out of nappies for almost 4months day and night. She has had two accidents during the day whilst playing with other kids but never an accident at night. She must have a monster bladder as she doesn't even wee when she gets up in the morning.
Eldest DD was out of nappies during the day before she was 2 but it wasn't until she was 3 that she stopped wearing a night nappy.
