Every year, over 2.3 million children under age 5 visit emergency rooms for injuries that happen at home. Knowing how to childproof your home before your baby starts crawling saves you from scrambling to cover hazards after the first close call. This room-by-room checklist walks through every major danger zone with specific products, installation tips, and the fixes that matter most.

Kitchen Safety: The Highest-Risk Room
The kitchen contains more hazards per square foot than any other room in your house. Start with cabinet locks on every lower cabinet, especially under the sink where cleaning chemicals are stored. Magnetic cabinet locks like the Safety 1st Adhesive Magnetic Lock set ($20 to $25 for 8 locks) mount inside the cabinet with adhesive and require a magnetic key to open. They leave no visible hardware on the outside.
Install a stove knob cover set on every burner control. Stove guard shields that mount along the front edge of the cooktop prevent small hands from reaching pots and pans. Secure your oven with a heat-resistant oven door lock that costs about $8 to $12. Move all knives, peelers, and scissors to upper cabinets or a locked drawer. Unplug small appliances like toasters and stand mixers when not in use, and wrap excess cord with a cord shortener.
Living Room and Common Area Hazards
Furniture tip-overs are one of the leading causes of serious injury for toddlers. Every bookshelf, dresser, and TV stand taller than 30 inches should be anchored to the wall with anti-tip straps or L-brackets rated for the furniture’s weight. A standard anti-tip furniture strap kit runs $6 to $10 and installs in five minutes with two screws into a wall stud.
Cover sharp furniture corners and edges with corner protectors. Foam corner guards adhesive-mount to coffee tables, hearths, and entertainment centers. Secure fireplace screens with wall-mounted brackets rather than freestanding models that a toddler can pull over. Relocate floor lamps and any freestanding items a child can topple. Blind cords are a strangulation hazard, so retrofit older blinds with cordless mechanisms or install cord cleats mounted high on the window frame.
Bathroom Childproofing Essentials
Drowning can occur in as little as one inch of water, making the bathroom extremely dangerous for unsupervised toddlers. Install a toilet lid lock on every toilet in the house. Lever-style locks that mount with adhesive run $5 to $8 each and prevent a child from lifting the lid.
Set your water heater to 120 degrees F maximum to prevent scalding. At 140 degrees F, a child’s skin can burn in under three seconds. Add an anti-scald device to the bathtub faucet as an extra layer of protection. Place a non-slip bath mat inside the tub and a non-slip rug on the bathroom floor. Store all medications, razors, and cleaning products in a locked medicine cabinet or a high shelf behind a childproof latch. Keep the bathroom door closed at all times using a door lever lock that mounts in seconds.
Bedroom and Nursery Safety
A safe crib is the starting point. The mattress should fit snugly with no more than two finger widths between the mattress edge and the crib frame. Slat spacing must be no wider than 2-3/8 inches. Remove all pillows, blankets, bumper pads, and stuffed animals from the crib during sleep.
Anchor the dresser and changing table to the wall. Install window guards or window stops that prevent windows from opening more than 4 inches. Move the crib away from windows, blinds, and cords. Once your child can climb out of the crib, typically around 35 inches tall, transition to a toddler bed with guardrails. Cover all electrical outlets in the room with outlet covers or switch to tamper-resistant receptacles, which cost about $2 to $3 per outlet to install yourself.
Stairways, Doors, and Gates
Hardware-mounted safety gates belong at the top and bottom of every stairway. Pressure-mounted gates are acceptable in doorways between rooms but should never be used at the top of stairs because a determined child can push them loose. Top-of-stair gates screw into the wall studs or stair posts and swing open for adult passage. The Regalo Extra Tall Top of Stairs Gate and the Summer Infant Multi-Use Gate are both rated well and run $35 to $55.
Use door pinch guards on every interior door hinge side to prevent crushed fingers. Doorknob covers on rooms you want to keep off-limits, like the garage, laundry room, and home office, prevent a toddler from turning the knob while still allowing adults easy access. Sliding door locks mounted at adult height keep patio and balcony doors secured.
Electrical and Fire Safety
Replace every standard outlet in rooms your child accesses with tamper-resistant receptacles (TRRs). Required by code in new construction since 2008, TRRs have internal shutters that only open when both prongs of a plug are inserted simultaneously. Swapping an outlet takes about five minutes if you are comfortable working with electrical. Turn off the breaker first and confirm power is off with a voltage tester.
For outlets currently in use, use outlet cover plates that automatically slide shut when the plug is removed. Secure power strips inside a cable management box to keep curious hands away from connections. Verify that every smoke detector and carbon monoxide alarm in the house is functional and less than 10 years old. Keep at least one fire extinguisher on each floor, mounted out of a child’s reach but accessible to adults.
Garage, Laundry, and Utility Areas
These spaces are often overlooked during childproofing but contain some of the most dangerous items in the home. Lock the door between the house and garage with a childproof knob cover or a deadbolt positioned above a child’s reach. Store all paints, solvents, pesticides, and automotive fluids in a locked cabinet or on shelving above 5 feet.
Front-loading washers and dryers attract toddlers who see them as play tunnels. Appliance locks that mount on the door prevent a child from climbing inside. Keep laundry pods in their original container inside a locked upper cabinet, as they are one of the top causes of pediatric poisoning calls. In the utility area, insulate exposed hot water pipes and secure the water heater with an earthquake strap if local code requires it.
Outdoor Spaces and Final Walk-Through
Fence your pool or spa on all four sides with a barrier at least 48 inches high and a self-closing, self-latching gate. Pool alarms that detect surface disturbance add another layer of protection for about $100 to $200. Inspect your deck railing for gaps wider than 4 inches that a small child could squeeze through.
After completing every room, get on your hands and knees and crawl through the house at a child’s eye level. You will spot hazards you missed from standing height, including small objects on the floor, accessible cords behind furniture, and reachable knobs or handles. Repeat this walk-through every three months as your child grows taller and more capable. Childproofing is not a one-time project but an ongoing adjustment as your child develops new skills and reaches new heights.
