Bed-wetting is not caused by a child being too lazy to get out of bed or as a bid to get attention. It is something that your child cannot control. Bed-wetting often runs in the family, so if you or your partner wet the bed as a child, then you may find that your child is similarly inclined.
What happens?
Bed-wetting happens when your child fails to wake from sleep despite a full bladder. At a certain point the bladder will then empty.Bed-wetters are often heavy sleepers who are difficult to rouse from sleep.Due to the low level of a hormone that controls urine output overnight, some children produce more urine at night than is normal.Some bed-wetters have small bladders that cannot hold a large volume of urine overnight without having to be emptied.
The Brain:
Tells the kidneys to produce less urine at night
Tells the bladder when to empty
The Kidneys:
Help clean the blood
Rid the body of urine
The Bladder:
Holds the urine until such time it can be gotten rid of
Signals the brain when the bladder is full
May empty by itself if the brain doesn't wake up your child at night
