What causes a child to be a enuresis(bedwetting)?

Condition analysis:
Bedwetting of the primary type does seem to run in families. So whatever the cause is, it is likely that children who are bedwetters have some sort of genetic reason. It's also possible one or both of their parents wet the bed.

The most popular theory is that bedwetters have a slight delay in maturation of their nervous system. When the bladder is full, the sleeping brain has to send a message down to the bladder not to pee. If your child's nervous system is a bit underdeveloped, the message might not get through.

Another theory is that children who are bedwetters are very deep sleepers. They are sleeping so soundly their brains don't tell their bladder to hold it.

Some experts also think that bedwetters may simply make more urine at night than other kids, and their bladder can't hold it all. Others hypothesize that their bladders have a smaller capacity to hold in the urine compared with kids who stay dry.

Instructions:
1) Easy on the Liquids:

Having too much liquid in the bladder is not the only reason why a child wets the bed. However, limiting the amount of liquid they consume before going to sleep gives them a little extra time before bedwetting will take place.

2) Avoid Watery Foods:
Some parents ignore the water content of the foods they may give their children before bedtime. Certain items, such as soup, many fruits and vegetables, and even yogurt, can contribute increased liquid in the bladder.
