Baby-proofing isn't one task, it's a handful of specific, well-studied risks — and the fixes for most of them take an afternoon, not a renovation.
Choking
The AAP notes choking is a leading cause of death for infants and young children, and roughly two-thirds of children who die from choking are under a year old. Cut food into pieces no larger than half an inch, and avoid whole grapes, hot dogs, nuts, seeds, hard candy, popcorn, and thick globs of peanut butter until your child is well past the toddler years. Always have your baby eat seated, never while crawling, walking, or playing — and keep balloons out of reach; they remain a top choking hazard up to age 8.
Falls, stairs, and windows
Install safety gates at both the top and bottom of stairs, mounted into the wall studs — avoid accordion-style gates, which can trap small limbs.
Open windows from the top only, or fit operable window guards.
Never leave a baby unattended on a bed, sofa, or changing table, even briefly.
Furniture and TV tip-overs
This one is more common than most parents realize: the AAP notes a child is treated in a US emergency department for a furniture or TV tip-over injury roughly once every hour, and 77% of tip-over deaths between 2000 and 2019 involved children under six. Anchor dressers, bookcases, and TV stands to wall studs using metal anchors (not the plastic ones that often ship with furniture), never place a TV on top of a dresser, and keep heavier drawer contents low.
Water safety
Drowning is the leading cause of death for children ages 1 to 4. A baby can drown in as little as two inches of water. Constant, within-arm's-reach "touch supervision" during any bath or pool time is non-negotiable — the AAP notes 69% of drownings in children under 4 happen outside of designated swim time. Empty bathtubs and kiddie pools immediately after use, and use four-sided isolation fencing around any home pool, which can prevent more than half of child drownings.
Poisoning

New guides go out the moment they're published — no noise in between.
Store cleaning products, medications (including anything in a purse or bag), alcohol, e-cigarette liquid, and button or lithium batteries locked, out of sight, and out of reach — in their original containers with safety caps intact. The NHS flags laundry and dishwasher detergent capsules specifically, since their bright colors and packaging can look attractive to a curious toddler. In the US, the Poison Help line (1-800-222-1222) is available 24/7 if you suspect exposure.
Crib and sleep-space safety
A firm mattress that meets current CPSC safety standards, nothing else in the sleep space (no pillows, bumpers, or soft toys), and room-sharing without bed-sharing for at least the first six months are the core of safe sleep — see our full guide to newborn sleep for the complete picture.
