Never leave a baby or toddler alone in the tub. Don't ask a sibling to watch a younger child in the water. Only adults should supervise. Do not rely on baby bath aides such as support rings. They are only intended to free your hands.
Hot water can scald or even kill a child.
Set your water heater no higher than 120 to 130 degrees. Empty all buckets after each use, and store out of a child's reach. Five-gallon buckets are increasingly the site of drownings of babies ages 7 to 15 months. Teaching by example is one of the best ways to encourage safe boating practices. Annually, about 300 children are injured or killed in boating related incidents.
