Did you know that there are about 5 million children in the United States who wet the bed?Even though most children are toilet trained between the ages of two and four, some children may not be able to stay dry at night until they are even older. It's important to understand that while you're potty training your child, every child develops at his or her own rate. In fact, according to the American Academy of Pediatrics, 20 percent of five-year-olds, 10 percent of seven-year-olds, and five percent of 10-year-olds may still wet the bed. Most children wet their beds during toilet training. Even after they stay dry at night for a number of days or even weeks, they may start wetting again at night. If this happens to your child, simply go back to training pants at night and try again another time. The problem will usually disappear as your child gets older. However, if your child reaches school age and still have problems wetting the bed, it most likely means they have never developed nighttime bladder control and you may need a different approach. How can you help your child quit wetting the bed? Wendy Sue Swanson, MD shares how you can put an end to bed-wetting.
