Supervision Never leave a young child unattended for even a second. Toddlers are naturally curious explorers and a second is all it takes for them to find trouble that may end in tragedy. According to the Consumer Product Safety Commission (CPSC) 75% of submersion victims were between 1 and 3 years old. Never assume another adult is watching your children, you must take full responsibility of their safety, particularly around water. When your child goes missing, always check the water first. .
