If your child wets himself, remember that however badly you feel about the inconvenience, it is likely that his embarrassment is much worse. Reassure him that you know it was an accident and that he hasn’t failed you. Being prepared for accidents will help both of you; always carry spare underwear and pants on trips.
Bedwetting at night can happen to a child of any age and is very common in children up to the age of five, boys being especially prone. Most children grow out of it after this age without any special help.
You will minimize your child’s embarrassment if you keep him in diapers at night until you are confident that he has reached the point where he can stay dry all night. Once you let him go without diapers, be prepared for the occasional accident. Concern about the frequency of bedwetting should not be communicated to your child; it only increases his anxiety. Encourage him instead by giving special praise if he has a dry night.
