Excessive water drinking. A marker of caretaker interaction disturbance.

In children examined at a child development clinic the incidence of excessive water drinking was almost exclusively confined to the foster care population. A series of 11 patients is compared with other reports of excessive water drinking as a marker for parent-child problems and inadequate nurturance. The parent-child interaction patterns were characterized as rejecting and both overprotective and overindulgent. The family adaptational styles tended to be chaotic and rigid, and the family cohesion styles disengaged or separated. Excessive water drinking can be considered a marker for problems in parenting.
