Bed Wetting 

Bed wetting or Enuresis is a psychosomatic disorder. Its an emotional disturbance causing dysfunction of organs controlled by autonomic nervous system. Many children with this disorder also have behavioural disorders. Such children are usually timid and  nervous. By age 5, one in five still wets the bed and at age 6, the numbers drop to one in 10. Boys are more likely than girls to wet their beds.

It is also suspected that bed-wetting may be caused by slow development of the nerves that control the bladder. Among other less common causes is Small Bladder. Even a small bladder unable to hold the urine produced during the night can result in bed-wetting. Bed-wetting can be a symptom of a serious illness (e.g., diabetes or a urinary tract infection), especially if it starts in a child who has previously been dry through the night.

Some Tips :

• Your patience and love will go a long way to help a child who wets the bed. Making the child feel guilty, getting angry or acting disgusted will only delay solving this problem. Try to be understanding and supportive.

• Set an alarm clock two to three hours after your child falls asleep so he or she can be awakened to go to the bathroom.

• Make sure your child urinates before getting into bed.
