First-time parents often ask me when bedwetting becomes a problem. The honest answer is that until age four or so, it is not really a problem at all. It is part of normal development, and how each child reaches dryness varies more than most parents expect.
The normal range
Most children stop wetting the bed somewhere between the ages of two and four. At age four, about 25 percent of children are still having wet nights. At age five, the figure drops to roughly 15 to 20 percent. The age at which a particular child becomes dry depends on physiological, cognitive, and emotional maturity, and none of these can be rushed.
If your child is three and still wets at night, that is not a problem. It is the middle of the normal range. The brain is still developing the overnight bladder control that older children take for granted.
Should you use pull-ups in this age range?
Yes. For children under four, pull-ups or nighttime diapers are perfectly reasonable. They keep the child and the bed comfortable, and they do not interfere with anything important, because there is no learning process to interfere with at this age.
This is in clear contrast to children of six or older in active treatment, where pull-ups absorb the signal that the alarm needs to detect. For a toddler or preschooler, that concern does not apply yet.
What not to do
Do not wake your child at night to walk them to the bathroom. This is one of the most common pieces of well-intentioned but counter-productive advice I hear. Waking the child trains a habit of urinating while half-asleep, which is the exact pattern we work to undo later. Better to let the child sleep and use a pull-up.
When to test for dryness
Summer is the best time to try a week or two without the pull-up. The laundry is easier, the child is more relaxed, and you get a clear read on whether the body is ready. If the bed is dry most mornings, drop the pull-up for good. If it is wet every night, go back to the pull-up without making a fuss, and try again in a few months.
When to consider treatment
If a child is approaching age four or older and is still wetting most nights, treatment becomes a sensible conversation. Before age four, the body is usually still finding its own way. Move at your child's pace, with their consent. Read more in our FAQ.
