My DD is 3.5. She has been potty trained in the day since she was 2 years 2 months, but still wears nappies at night. If she didn't wear them she would wet the bed every night.
I know there is a hormone that is responsible for bladder control at night so have not really tried any sort of night time potty training as it seems that if she is not yet producing this hormone then there'd be no point.
My questions is, when should we expect her to be dry at night? My older DD was dry at night around 3.
