Babies under one should be supported at all times when in the water. Water wings, inner tubes, and other flotation devices may give a false sense of security and should not be used in deep water. Never allow a child to dive into the shallow end of the pool or into water of unknown depths. Children should always wear a life preserver when in a boat. A life preserver is properly fitted if you cannot lift it over a child's head once it's been fastened.
Summer time is meant to be fun.
