Primary nocturnal enuresis is the medical term for a child who has been wetting the bed since he or she was a baby. It's the most common form of bedwetting and is only considered a disorder until the child is old enough to stay dry.
"The two things that are going on for that child is that they are sleeping way too soundly and overproducing urine at night," pediatrician Manny Cirenza said.
About 15 percent of children ages 5 to 6 still wet the bed, but that number declines as they get older.
"Ten or 11 percent of 6-year-olds, 7 or 8 percent of 7-year-olds, and 5 or 6 percent of 8- and 9-year-olds," Cirenza said.
If your child suddenly becomes a bedwetter, it may the result of anxiety or stress. Although it's rare, anatomical issues need to be ruled out.
"You are going to need a urinalysis to make sure the kidneys are making appropriate urine and secondarily to make sure there is nothing wrong with the urological system," Cirenza said.
For children who are still wetting the bed, there are several options available to combat the problem, including limiting fluids before bed and bedwetting alarm pads that will alert your child when moisture touches the pad. When they are old enough to do sleepovers, there is even medication to help keep them dry overnight.
"DVAVP is a tablet or nasal spray they can use before they go to bed and this DVAVP is basically antidiuretic hormone," Cirenza said. He added that the treatment is safe because it's simply "replacing what should be occurring naturally in them."
