Here are several strategies you can try to help your child stop wetting the bed:
Limit how much your child drinks after dinner.
Encourage your child to empty his bladder a second time, just five minutes after the first time, right before bed.
Wake your child during the night to go to the toilet - although some experts say that if she's not really awake, it's almost like encouraging her to pee while she's sleeping. Nonetheless, it can help you avoid the added laundry.
And, place a potty by your child's bed so that if he wakes up and has to go quickly, he can.
If the bedwetting continues despite all your efforts, consult your child's doctor for more specific strategies.
