Water safety in the Bathroom - By Baby Centre

The most important thing to remember is to never leave your young child unattended in a bathtub, even for a minute. If the phone rings and you must answer it, wrap your child in a towel and take her with you.
Other ways to help keep your child safe:

• Cover the bottom of the tub with a rubber suction mat to prevent slipping, and fill the tub with only 3 to 4 inches of warm water. If your baby can't sit up securely on her own, support her back so she stays upright.
• For kids who can sit up, a bath ring may provide you with an extra "hand." But don't let it give you a false sense of security: Babies can tip over or get trapped under them, so it's no substitute for keeping your eye – and a hand – on your baby at all times.
• Keep the toilet lid down and the bathroom door closed, or get a lid lock for the toilet.
