However, children who do not get help or who are punished for bed-wetting might develop emotional or behavioral problems. Most children stop wetting the bed at night by the time they are four or five. Children who continue to wet should be assessed by a pediatrician or a family doctor. This may be a sign of more serious problems. Since infection of the urine can cause wetting in a few cases, every child with wetting needs to be checked.
Some children produce more urine during sleep than others.
Other children have bladders that do not hold as much urine. Physical problems are uncommon causes of bed-wetting but should be considered in every child. A good history, thorough physical examination, and urine test are usually all that is necessary to determine if a physical problem is likely. Most children who wet their beds do not have a kidney problem. The best way to help prevent this is to reassure your child that bed-wetting is a common problem and that he or she will outgrow it.
