You are caring for a 5-year-old whose mother asks why he still wets the bed. What is your best response? 1) He is old enough that he should no longer be wetting the bed. 2) Most children outgrow bed-wetting by the time they start school. 3) His bed-wetting may be due to an immature bladder or deep sleep pattern. 4) He will probably stop once he realizes how embarrassing it is to wet the bed.
