I'm a bit confused about whether or not I should be toilet training my DD (4 a couple of weeks ago) at night. She has been reliably dry during the day for over a year now (barring the odd accident). When she was potty training, I read about the hormone that is meant to develop and enable them to be dry at night, and I guess I thought it would have happened by now. Should I be doing anything to encourage her to be dry at night? Or do I just wait until she is ready? She always has a full nappy in the morning, so she is definitely not waking up to wee.
