Baby Proofing Checklist: Start at 4 Months (Room by Room)

Hilly Shore Inc.··Updated October 12, 2026·10 min read

Quick Answer

Begin at four to five months, before your baby is mobile, and work in risk order rather than room order: anchor furniture and televisions, never leave a baby near water, switch to cordless blinds, and lock away cleaners and medicine. Then hardware-mount a gate at the top of the stairs and crawl the house at your baby's eye level — you will find hazards standing adults never notice.

Our Verdict

Four hazards carry most of the risk: furniture and TV tip-overs, water, window-covering cords, and unlocked poisons. Anchor, supervise, go cordless and lock before you buy corner bumpers or a magnetic drawer kit. Hardware-mount the gate at the top of the stairs; pressure-mounted gates belong in doorways and at the bottom only, and plug-in outlet caps become a choking hazard once a toddler works one free.

Key Takeaways

  • ✓Start baby-proofing your home at 4-5 months of age, before your baby becomes mobile. Babies roll before they crawl, and once they move, things happen in seconds.
  • ✓What most people get wrong: Outlet covers and cabinet locks feel like "baby-proofing," so parents do them first — they're cheap and visible.
  • ✓The room with the most furniture, the most cords, and the most floor time.
  • ✓The highest concentration of poisons, heat, and pinch points in the house.
  • ✓Small, but it holds two of the deadliest hazards: standing water and medication.

Complete Baby Proofing Checklist: Room by Room

Start baby-proofing your home at 4-5 months of age, before your baby becomes mobile. Babies roll before they crawl, and once they move, things happen in seconds. Print this, then walk each room on your hands and knees at your baby's eye level. The order is deliberate: the hazards that seriously injure and kill young children come first, the nice-to-haves last.

The four hazards to proof first

HazardWhat to doWhy it comes first
Furniture and TV tip-oversAnchor dressers, bookcases, TV stands and the TV itself to a wall studCPSC estimates a child is treated in an emergency department for a tip-over injury every 53 minutes
WaterNever leave a baby alone in or near water; empty tubs and buckets right awayDrowning is the leading cause of death for children ages 1 to 4, and it can happen in an inch or two of water
Window-covering cordsGo cordless, or keep every cord permanently out of reachCPSC says about nine children under 5 die each year strangled by window-covering cords
PoisonsLock away cleaners, medicines, vitamins and laundry podsChild-resistant caps slow toddlers down but don't stop them

What most people get wrong: Outlet covers and cabinet locks feel like "baby-proofing," so parents do them first — they're cheap and visible. But anchoring, water supervision and cordless blinds address the hazards linked to death and serious injury. A covered outlet next to an unanchored dresser is a false sense of safety.

When should I start baby-proofing my home?

Before your baby is mobile — around four to five months — and then again at each new skill. Use milestones as the trigger, not the calendar. The CDC's milestone checklists give the ages by which most children reach each skill:

By aboutWhat most babies can do (CDC)What it unlocks
6 monthsRoll from tummy to back, push up on straight armsReaching sideways, grabbing cords and small objects
9 monthsGet to sitting alone and sit without support; many crawl or scoot around nowFloor-level outlets, under furniture, pet bowls, stairs
12 monthsPull up to stand, walk holding on to furnitureTip-overs, tabletops, drawer pulls, window sills
18 monthsWalk alone, climb on and off a couch or chairCounters, dressers, toilet lids — everything higher up

If you wait until your baby is already crawling, you'll be playing catch-up in a house full of hazards.

Living Room

The room with the most furniture, the most cords, and the most floor time.

Furniture and TV anchoring

Bookshelves, dressers, TV stands, and any tall or top-heavy furniture should be anchored to a wall stud with anti-tip straps — a kit like the Quakehold Furniture Strap Kit → covers one piece. Anchor the TV as well as the stand it sits on; both can come down together.

If you do one thing: Anchor the furniture. This is the single most important baby proofing step.

Children account for 71% of the tip-over deaths reported to the CPSC, and its Anchor It! campaign asks families to anchor furniture and TVs however heavy they look. New dressers and other clothing storage units made since September 2023 must pass a mandatory federal stability standard under the STURDY Act, but older dressers, bookcases and TV stands aren't covered by it. If your dresser came with an anti-tip kit, install it rather than leaving it in the box.

Corner and edge protectors

Coffee tables and fireplace hearths are notorious head-bump zones. Safety 1st Foam Corner Protectors → and edge bumpers cushion hard surfaces. They're inexpensive and can be removed without damage when no longer needed. Secure the fireplace with a hearth gate and pad sharp stone edges.

Electrical outlets

Cover accessible outlets with sliding plate covers that close automatically, or have an electrician fit tamper-resistant receptacles, whose internal shutters block a single inserted object; the National Electrical Code has required them in new US homes since 2008. Standard plug-in covers can be a choking hazard if a toddler manages to pull one out.

Cords and window coverings

  • Replace corded blinds with cordless versions. In the more than 200 corded window-covering incidents involving children that CPSC reviewed from 2009 to 2021, a child died in nearly half
  • Bundle and secure TV cords, lamp cords and charging cables out of reach, or route them behind furniture
  • Use cord covers that attach to the wall or baseboard

Small objects

Get on the floor at baby's level and scan for anything smaller than a toilet paper tube:

  • Coins
  • Button batteries and magnets
  • Pen caps
  • Small toys from older siblings
  • Pet kibble

Worst case: Button batteries are especially dangerous and can cause serious internal injuries if swallowed.

Kitchen

The highest concentration of poisons, heat, and pinch points in the house.

Cabinet and drawer locks

Start with the cabinet under the sink, where cleaning products and dishwasher pods live, then every low cabinet and drawer holding knives, glass or chemicals. Safety 1st Secure-to-Explore Adhesive Cabinet Locks → handle most doors. Safety 1st magnetic cabinet locks → are invisible from outside and harder for clever toddlers to defeat, though slower to open with your hands full.

  • Store chemicals in their original packaging, up high and locked — never decant into cups or bottles (and see what to look for in baby-safe cleaning products to shrink what lives under the sink)
  • Keep single-use laundry and dishwasher packets out of sight and reach; they're concentrated and can burst in a child's mouth or eyes

Stove, appliances and table

  • A stove knob cover set prevents your toddler from turning on burners
  • Cook on back burners when possible and turn pot handles inward
  • Use the dishwasher's child lock (or a latch) when you're not loading it — it holds sharp utensils and detergent residue
  • A locking trash can and a fridge lock matter once your child can walk and reach handles
  • Skip tablecloths and dangling placemats a baby can yank
  • Keep the high chair away from counters and walls the baby can push off from

Bathroom

Small, but it holds two of the deadliest hazards: standing water and medication.

Bath safety

No exceptions: Never leave a baby or toddler unattended in the bath, even for a moment. The AAP notes that young children can drown in as little as an inch or two of water, quickly and silently. Stay within arm's reach.

  • Empty the tub, buckets, and any standing water immediately after use
  • Set your water heater to 120 degrees Fahrenheit maximum to prevent scalding, and test bathwater with your wrist
  • A faucet cover protects baby's head from the hard spout; a non-slip mat prevents slipping

Toilet, medicine and door

  • Toilet lock on every toilet in the house, not just the one nearest the nursery
  • Medications, vitamins and supplements locked away — including anything in a purse, bag or nightstand. Save the Poison Help line: 1-800-222-1222
  • Hair dryers, straighteners and razors unplugged and stored out of reach
  • A door lever lock or high hook-and-eye latch keeps the bathroom closed when not in use

Nursery

The room you'll trust them alone in. Get the sleep surface and anchoring right.

  • Crib: a firm mattress with a fitted sheet only — no pillows, blankets, bumpers or stuffed animals (see our safe sleep environment guide). Slats no more than 2-3/8 inches apart, and the mattress lowered to its bottom setting once baby can sit or pull up
  • Dresser and changing table anchored to the wall. A climbing toddler can create enough leverage to tip furniture that feels too heavy to fall
  • Windows: install window stops or guards that keep windows from opening more than four inches, and move the crib away from windows, cords and wall hangings
  • Monitor cords at least three feet from the crib, secured out of reach (mounting tips here)
  • Changing table: never walk away mid-change, strap or not

Stairs and Hallways

For an awkward stair opening, use the guide to measuring a banister-and-baseboard opening. It separates post fit, wall fixing and final gate width rather than assuming a no-drill accessory makes every gate suitable.

Baby gates

Gates at the top and bottom of stairs are essential once baby is mobile. The critical rule: only hardware-mounted gates at the top of stairs. Pressure-mounted gates can be pushed out, so they belong in doorways and at the bottom of stairs only. Our best baby gates for stairs guide covers which gate fits which opening.

Gates sold in the US must meet the CPSC's mandatory standard for gates and enclosures (16 CFR part 1239), which incorporates ASTM F1004. Gate off rooms you can't fully proof — a home office, the laundry room, the garage entry — rather than proofing every item in them.

Hallway hazards

  • Check banister gaps and add a banister guard if a small child could slip between the balusters
  • Secure loose rugs with non-slip pads
  • Add a night light for nighttime trips while carrying baby

Garage and Outdoor Areas

  • Keep the door from the house to the garage locked
  • Store chemicals, tools, paints and automotive supplies in locked cabinets or high shelves
  • Test the auto-reverse sensors on garage doors regularly
  • Check fencing for gaps, and store gardening chemicals and tools out of reach
  • If you have a pool or hot tub, install a four-sided fence with a self-closing, self-latching gate

What is the crawl test for baby proofing?

After baby proofing each room, get on your hands and knees and crawl through it. Then repeat this 10-minute sweep every few months as your baby's reach grows:

  • Look at their height for cords, outlets, gaps, and small objects you'd miss standing up
  • Tug-test every anchor — dresser, TV, bookcase, gate
  • Walk the house for water: tub, buckets, pet bowls, toilet
  • Scan for cords: blinds, chargers, lamps, monitor, kettle
  • Check for chokeables: anything that fits through a toilet-paper tube

Proofing is a layer, not a substitute

Baby proofing doesn't need to happen all at once, but the four priority hazards — tip-overs, water, cords and poisons — plus stair gates should be handled before your baby is mobile. Start with the rooms where you spend the most time and work outward. The priority items cost far less than the premium gadgets marketed alongside them.

No product replaces an adult's attention. Drowning-prevention guidance treats supervision as the primary layer and barriers as backup, never the reverse. Latches buy you seconds when you turn your back; they don't make it safe to turn your back. Add these items to your newborn essentials checklist so you're ready before mobility begins, and browse our baby gates and childproofing picks for the gear itself.

Myth

If baby-proofing products have a safety certification, they're completely safe.

Fact

No baby-proofing product replaces supervision. Products can fail, and determined toddlers can defeat most safety devices. Think of them as a delay tactic, not a guarantee.
