Why can't I stay dry at nights?

This fictional story is about a condition of bedwetting called 'Nocturnal Polyuria'. This condition is caused by a lack of surge for a hormone called 'Vasopressin', which decreases the urine production at night for children. However when the surge is missing, the children can get full bladder many times at nights, resulting in multiple episodes of bedwetting. This condition should be treated under supervision and guidance of a specialist having expertise in bedwetting, and monitored under their medical supervision. This broadcast is recorded for parents, to share with their children if affected.
