As a pediatric urologist, I know that, as The Times reported recently, the popular laxative Miralax isn't (gasp!) F.D.A.-approved for children. I still prescribe it daily. I believe Miralax's active ingredient (polyethylene glycol 3350, or PEG) is safe for kids. The problem isn't overuse in children; it's underuse.

But what folks don't realize is that along with childhood obesity, childhood constipation is epidemic. A stool-stuffed rectum, encroaching upon the bladder, is the main cause of bedwetting, accidents, urinary frequency and other stressful toilet troubles that I see in my practice.
