Toddlers are naturally drawn to water. It sparkles, splashes and makes toys float, but a young child does not understand that water can be dangerous. According to the American Academy of Pediatrics, drowning is the leading cause of death in children ages 1 to 4, and it can happen in as little as an inch or two of water, quickly and silently. The good news is that most of these tragedies are preventable when families use multiple layers of protection.

Quick guide: Stay within arm’s reach whenever your toddler is near water. Empty buckets and wading pools after use. Surround pools with a four-sided fence and a self-closing, self-latching gate. Learn CPR and start swim lessons when your child is ready.

Why toddlers face the highest drowning risk

During the toddler years, children can walk, run, climb and explore, but they cannot yet recognize danger or remember a warning to stay away from water. The American Academy of Pediatrics notes that 69% of drownings among children age 4 and younger happen during non-swim times, when nobody expected the child to be in the water. Safe Kids Worldwide reports that, among preventable injuries, drowning is the leading cause of death for children 1 to 4 years old. The U.S. Consumer Product Safety Commission adds that most young drowning victims had been missing for five minutes or less when they were found, and that drowning often happens without splashing or screaming. Because a toddler can slip under the surface silently, prevention must be built into the environment.

In-home water hazards you can address today

The CPSC states that nearly 90 children drown inside the home each year, and two-thirds of those deaths occur in the bathtub. A child can drown in as little as 2 inches of water, which means everyday containers become risks. The AAP’s guidance for 1- to 2-year-olds stresses that a toddler should never be left alone in or near a bathtub, a bucket of water, a wading pool or any other water, even for a moment. Empty all buckets after each use. Coolers with melted ice, large pet water bowls and trash cans that collect rainwater should also be emptied or kept out of reach.

Bathrooms need special attention. The AAP recommends using safety latches or doorknob covers to keep bathroom doors closed when the room is not in use. As an added layer, install latches or locks on toilet seat lids and consider removing the bathtub drain plug so the tub cannot fill if a child turns on the faucet. The CPSC reminds families that no device is completely childproof; determined toddlers have been known to overcome latches and locks. That is why physical barriers work alongside constant supervision. For a room-by-room look at reducing risks, see our bathroom safety guide.

Layers of protection for pools and spas

Most toddler drownings happen in backyard pools, according to the CPSC. The AAP and the CPSC both recommend a four-sided isolation fence that completely separates the pool from the house and the rest of the yard. The fence should be at least 4 feet high, with no openings under it or between slats wider than 4 inches. The gate must be self-closing and self-latching, and it should open away from the pool. The AAP specifies that the latch should be at least 54 inches from the ground. Keep the gate locked and check it frequently to be sure it closes and latches correctly. When the pool is not in use, remove toys from the area so children are not tempted to try to get through the fence.

If the house forms one side of the barrier, the CPSC advises adding door alarms or a power safety cover over the pool. The Pool Safely campaign also suggests installing a door alarm on any door that leads from the house to the pool area. After each swim session, reestablish every barrier. Covers, gates and alarms are not substitutes for supervision, but they create valuable delay during the moments a caregiver is not looking.

Hot tubs, spas and whirlpools should be covered and locked immediately after use. The AAP also recommends removing or fencing other backyard water features such as bird baths, fountains, ponds, wells and drainage ditches until children are older. Open post holes dug during construction projects should be covered or blocked so a curious toddler cannot fall in.

Supervision: the layer that never rests

Even with strong barriers, close supervision is essential. The AAP recommends “touch supervision,” meaning an adult stays within arm’s length of a toddler whenever the child is in or near water, whether at bath time or swim time. Most child drownings inside the home occur in bathtubs, usually during a brief lapse in supervision. The AAP says children should not be allowed to bathe alone until they are at least 6 years old, and a young sibling should never be left in charge.

During swim time, get in the water with your toddler. If you need to step away, take the child with you, even when lifeguards are present. The Pool Safely campaign encourages families to designate a “water watcher” whose only job is to keep eyes on the children. The AAP suggests passing a water watcher card to another responsible adult every 15 to 20 minutes so the watcher stays alert. Put away phones, books and other distractions. Have a phone close by in case you need to call for help, and if a child is missing, always check the pool or spa first.

Near lakes, rivers and other natural bodies of water, children should wear a U.S. Coast Guard-approved life jacket that fits properly. The AAP cautions against using floaties, water wings or inflatable toys; they can deflate and do not prevent drowning. Children who lack strong swimming skills should also wear a life jacket at a pool or water park.

Swim lessons and CPR: skills that save lives

The AAP recommends swim lessons for all children and their parents as another layer of protection. Lessons can begin after a child’s first birthday, but readiness depends on factors such as how often the child is around water, emotional maturity, physical abilities and comfort in the water. A pediatrician can help families decide when to start. Parent-child swim lessons are a practical way to build skills together, and the AAP notes that at least 15% of people in the U.S. say they cannot swim. When parents learn, the whole family becomes safer.

Being ready to respond is just as important. The CPSC and the Pool Safely campaign urge parents and caregivers to learn CPR and safe rescue techniques. CPR classes are available through hospitals, community centers and the American Red Cross. Keep certification current. In an emergency, call 911. If you suspect a child has ingested a poisonous substance, contact Poison Help at 1-800-222-1222. For any injury, follow the guidance of your child’s pediatrician.

Frequently asked questions

Can I rely on a pool cover or alarm instead of a fence?

No single device can prevent all drownings. The AAP and CPSC both stress that layers work together. A four-sided fence with a self-closing, self-latching gate is the foundation. Covers and alarms add extra protection, but they do not replace a proper barrier or constant supervision.

At what age can a child be left alone in the bathtub?

The AAP recommends that children not be allowed to bathe alone until they are at least 6 years old. It also says not to let another young sibling supervise children under this age.

Do swim lessons make my toddler drown-proof?

No. The AAP states that knowing how to swim does not mean a child is safe near or in water. Swim lessons are one layer of protection, but they must be combined with touch supervision, barriers and life jackets when appropriate.
