Helmets: Many websites can show you the basics of fitting helmets for biking and other activities. The important thing to know is that kids copy their parents, so parents must wear their helmets too.
Trampolines: Injuries like broken bones, concussions, and sprains are common. The American Academy of Pediatrics recommends that trampolines never be used at home, in routine gym classes, or on playgrounds.
Drowning is the leading cause of death from injury for children 1 to 4 years old. Everyone should know the basics of floating and moving in the water. Formal swimming lessons have been shown to decrease the risk of drowning. Children should always be closely supervised, even if they know how to swim. Pools should be fenced on all 4 sides. Use life jackets around natural bodies of water like lakes or oceans. Small bodies of water, like fish ponds or fountains and even buckets, can attract children. Toddlers may fall forward into them and drown.
