WHY DOES IT HAPPEN?

GENETICS: Up to 70% of parents did the same thing.

CAFFEINE: Food and drinks that contain caffeine (coffee and tea) can make the problem worse.

CONSTIPATION: A third of all children who wet their beds struggle with constipation.

BLADDER INFECTIONS: Bladder infections could lead to wetting the bed.

SLEEP APNOEA: This is a rare cause of nocturnal enuresis.

ATTENTION DEFICIT: Bedwetting is more common in children with attention deficit and those who are hyperactive.

STRESS: The birth of a younger sibling, a hospital stay, problems at home, bullies at school, moving house or sexual abuse can cause a child who never wet their beds to start doing so.
