But keeping youngsters safe and sound around them requires vigilance and good sense, experts say. These guidelines can help keep your kids out of harm’s way:

Small children can drown easily in water they can stand in. No pool — not even a foot-deep plastic kiddie pool — is drown-proof. To help protect children:

• Never leave a child to play in a pool of any size without a responsible adult in attendance at all times. A child can drown in the minutes it takes for an adult to run inside to answer the phone or door, or use the bathroom.
• Make a child who can’t swim wear a life jacket at all times near or in a swimming pool. Flotation rings, inflatable rafts or plastic foam “noodles” aren’t safe substitutes for life jackets.
• Have an adult in the pool at all times with a nonswimmer, even one wearing a life jacket.
• Surround a home pool with a fence that has a self-locking gate.
• Empty portable kiddie pools after each use and turn them on their sides so they can’t collect water.

The Consumer Products Safety Commission says hospital emergency rooms treat an estimated 95,000 children with trampoline injuries each year. Those injuries include broken bones, concussions and other head injuries, neck and spinal injuries, sprains, cuts and scrapes.

If you allow your children to jump on a trampoline, these precautions may help head off injuries:

• Don’t let any child younger than age 6 use a full-size trampoline. Adults should supervise all children.
• Install shock-absorbing pads to cover the steel frame, springs and hooks.
• Place the trampoline in a hole in the ground, so the jumping surface is near to ground level.
• Cover the surface under and around the trampoline with wood chips, sand or the type of rubber matting found in playgrounds.
• Consider getting safety fencing to reduce the risk a jumper will fall off.
• Only let one child at a time use a trampoline.
• Don’t let anyone do somersaults or other high-risk maneuvers on a home trampoline.
