Although by age 8 most youngsters have outgrown bedwetting, a sizeable minority still haven’t. As a matter of fact, 5 to 10 percent of boys still have enuresis (the medical term for bedwetting) by age 10. Enuresis tends to run in families and, when this is the case, children usually outgrow it at the same age as the parent, sibling or other relative who had the problem did.
No one knows what causes bedwetting, although it is sometimes associated with constipation. If so, simple dietary changes such as eating more fruits and vegetables and drinking more water early in the day can help resolve matters. Pediatrician Sandy Newmark, MD, of Tucson, Ariz., suggests making sure that children aren’t drinking any beverages that contain caffeine (such as some sodas) and trying to limit (within reason) the amount of fluids they drink in the evening.
