Children can drown in just a few inches of water. So, it is imperative that they are supervised at all times when they are in and around water. Backyard pools must be fully fenced, with a self latching gate. Have a phone and first aid kit on hand. If taking children out on the water, ensure that they each have a properly fitted life jacket. As a parent you should take a first aid / CPR course, so that you are fully prepared for an emergency.
