pretty much nothing. Nocturnal enuresis is a condition studied for over one hundred years and what we in medicine have learned is that it is probably inherited and will stop sometime before or during puberty. However, day and night time wetting is different and requires medical attention. Therefore, do what is comfortable for her--pull ups at night etc until it stops. There are medicines to help for overnight and camp stays. Ask your pediatrician about those, and be sure your pediatrician knows what is happening.
