 If your toddler falls in the pool, you think you'll hear this. But what you'll really hear is this. It happens quickly and silently. About 260 children younger than 5 drown in pools each year. That's about one nursery school class each month. Put a fence around your pool. A nice alarm on doors leading to the pool area. If a child is missing, look in the pool first. Remember, every second counts. When the toddler drowns, it often happens quickly and quietly. Many times children slip under the water with hardly a sound. Parents may think that if their child falls in the pool, they will hear lots of splashing and screaming. They think they'll be able to come to the rescue. But young children can slip under water silently. Often even people nearby report hearing nothing out of the ordinary. No one layer of protection is foolproof to prevent drowning in pools. Use as many layers of protection as possible. Multiple barriers and constant supervision are essential to protecting children. When a child drowns, it usually happens quickly and silently.
