Bedwetting

Almost all mothers encounter bedwetting—nocturnal enuresis. Most kids become fully toilet trained between ages 2 and 4 — but there's no target date for developing complete bladder control. Girls learn faster than boys.

Causes

Kids, who wet the bed are not able to feel that their bladders are full and don't wake up to use the toilet.

During childhood, some kids don't produce enough anti-diuretic hormone, or ADH, to slow nighttime urine production.

A urinary tract infection can make it difficult for child to control urination.
Sometimes bed-wetting is a sign of obstructive sleep apnea, a condition in which the child's breathing is interrupted during sleep — often because of inflamed or enlarged tonsils or adenoids.

For a child who's usually dry at night, bed-wetting may be the first sign of type 1 diabetes, if it is accompanied with passing large amounts of urine at once, unusual thirst, fatigue and weight loss in spite of a good appetite.

Sometimes children who don't have regular bowel movements retain urine as well. This can lead to bed-wetting at night.

Sometimes a kid who wets the bed will have a realistic dream that he or she is using the bathroom.

Many kids who wet the bed are very deep sleepers.
Bedwetting may also be the result of the child's tensions and emotions that require attention.

Enuresis runs in families.

Bedwetting revisits

When a young child begins bedwetting after several months or years of dryness during the night, this may reflect new fears of insecurities. These include losing a family member or a loved one, arrival of a new baby, change of home.

Prevention

Limiting liquids before bedtime
Encouraging the child to go to the bathroom before bedtime
Praising the child on dry mornings
Avoiding punishments
Waking the child during the night to empty their bladder

Bedwetting goes away on own. Children rarely wet on purpose, and usually feel ashamed about the incident. A pediatrician's advice is often very helpful.
