27. Always Supervise Children Near Water
This cannot be overstated enough. Most children who drown do so just a few feet from their caregivers. Children who experience secondary drowning often become submerged when their parents or caregivers turned their backs for just a moment.
When children that you are caring for are swimming, do not let them out of your sight. Don’t assume that just because a lifeguard is on duty, that he or she is as vigilant as you are. The lifeguard will be thereto help in case of an emergency, but your responsibility to the children in your care is to prevent that emergency in the first place.
