Understand that developmentally, each child is different. Some children can stay dry at night during the toddler years; others are still having accidents at age six or beyond. Try not to compare your son or daughter to other children.

As your child gets older, you may want to enlist his or her help in this routine. Most preschoolers can remove soiled sheets, put on clean pajamas, and help you put clean linens on the bed.

Take special care to avoid caffeinated drinks (like sodas). These can increase the production of urine.

Particular culprits seem to be salty snacks, sugary drinks, spicy and acidic foods, which can irritate the bladder, and milk and other dairy products, which can cause sleepiness and make it harder to wake up when the bladder is full.

Ideally, the temperature of the water should be about body temperature: 98. 6 degrees Fahrenheit or 37 degrees Celsius.

See a pediatrician if your child is older than seven years old and still wetting the bed. A pediatrician can help rule out other causes (including urinary tract and bladder infections) and give you advice for helping your child stay dry. See a pediatrician if your child is older than five years old and still having accidents during the daytime as well as at night. By five years old, most children should be able to control urination. If yours can’t yet, see a pediatrician to rule out physical causes and get advice for treatment, but be aware that this problem can be genetic: you may simply have to wait it out. See a pediatrician and/or a child psychologist if your child begins to wet the bed again after a long period of dry nights. Under these circumstances, bedwetting may be linked to trauma or stress: the death of someone close to the child, divorce of his or her parents, the arrival of a new baby, or anything else frightening or disruptive.
