Parents who demand rapid toilet training may generate an angry response, the child unconsciously defy them by wetting the bed. But on the other hand parents who do not understand the timely need of toilet training may undermine childs effort to control the bladder. One hypothesis also suggests that these children sleep deeply hence signal from distended bladder indicating the need to empty the bladder does not reach the conscious level of their brain during sleep. This type of bedwetting is precipitated by stressful environmental events such as birth of a sibling, death in family, marital conflict and moving to a new home. This type of bedwetting is transitory.
Prognosis is better and management is easier than persistent type.
In both types of bedwetting organic pathology is found only in small number of cases.
