The Preschool Safety Checklist: Choking, Car Seats, Water, and More

In one minute

• Choking remains a top preventable injury risk through age 5 — cut round or firm foods small, and keep meals seated and supervised.
• Car seat needs keep changing with size: keep a 5-point harness until your child hits the top height or weight limit printed on their specific seat -- often well past 40 lb and age 4 -- then move to a booster until the adult seat belt fits properly on its own, usually around age 8-12.
• Never leave a preschooler alone near water, even one who "swims well."
• Simple habits — locked-up meds and chemicals, pot handles turned inward, furniture secured, a helmet every ride — prevent most everyday injuries.

Food and choking

Choking is still the leading cause of unintentional injury death for kids under 5, and grapes, hot dogs, nuts, popcorn, and hard candy are repeat offenders. Cut food into pieces smaller than half an inch, quarter grapes and cherry tomatoes lengthwise, and keep whole nuts, seeds, popcorn, hard candy, and chewing gum off the menu until at least age 4, ideally 5 -- this isn't about how well your child chews; their airway is still narrow and their back molars are still coming in. Meals should happen seated at the table, unhurried, without running or playing.

On the road and near water

In the car, keep your child in a 5-point harness seat until they reach the top height or weight limit printed on their specific seat — for many seats that's well past 40 pounds and age 4. Only then move to a belt-positioning booster, and stay there until the adult seat belt fits properly on its own, usually around age 8 to 12 (roughly 4 feet 9 inches) — always in the back seat. Near water, constant, close supervision is non-negotiable, even for a confident young swimmer; drowning happens silently and fast. On bikes and trikes, a properly fitted helmet belongs on every single ride.

Around the house

This is the age of testing limits — climbing higher, running faster — so secure heavy furniture and TVs to the wall, use gates at stairs, and check play equipment for safe surfacing. Store medications, cleaning products, and matches out of reach or locked up, and turn pot handles toward the back of the stove. If firearms are present anywhere your child spends time, ask whether they're stored unloaded and locked, separate from ammunition.

When to seek emergency care: choking that doesn't clear on its own, a head injury with vomiting or confusion, unresponsiveness, trouble breathing, a suspected poisoning (in the US, Poison Control: 1-800-222-1222; outside the US, contact your local poison control centre or emergency number), or a severe burn or bleeding.
