Baby-Proofing the House: What to Do, Room by Room

Most parents plan to baby-proof before the baby moves and end up doing it the week the baby first manages to roll across the playmat to the bookcase. The good news is most of the work is genuinely cheap, takes a Saturday afternoon, and dramatically reduces the things that put small children in hospital. The aim isn't a sterile environment — exploration is how children develop — it's removing the small set of high-consequence hazards so the rest can happen safely. For a comprehensive overview, see our complete guide to child safety. Healthbooq tracks development so you can see the next mobility stage coming.

When to Do It

The right window is around five months, before independent movement starts. Babies at this age are starting to roll, and the first injuries usually involve falls from changing tables, beds, or sofas — surfaces parents had assumed were safe. If your baby is already crawling, no panic; most hazards can still be addressed in an afternoon and a Saturday morning trip to the hardware shop.

Re-do the walk-through at each new mobility stage:

• Rolling (4–6 months): falls from changing tables, beds, sofas; smothering hazards in the cot
• Sitting (6 months): small objects within reach
• Crawling (6–10 months): floor-level hazards — sockets, low cupboards, small objects, trailing wires, fireplace
• Pulling to stand (8–12 months): low tables, drawers, anything around 60–80 cm height, the cooker
• Cruising (9–14 months): counters, the contents of low cupboards now opened experimentally
• Walking (12–18 months): doors, stairs, ability to disappear into another room while you blink
• Climbing (18 months+): chairs scaled to reach the kitchen counter, cot escapes, climbing into baths

Each stage brings new things into range. The bookshelf that was unreachable last week is a climbing wall this week.

The Highest-Risk Hazards (Address These First)

These are the ones that show up most often in serious injury data, and they're worth doing first regardless of room:

Furniture and televisions tipping over. Bookshelves, chests of drawers, TVs on stands, dressers, freestanding wardrobes. A toddler pulling a drawer open uses it as a step; the unit tips. Anchor everything tall with wall straps or brackets (£5–10 from any DIY shop). Most flat-pack furniture comes with these now and most people throw them away during assembly. RoSPA flags this as a leading cause of serious crush injury in under-fives.

Blind and curtain cords. Strangulation hazard, particularly looped cords near cots, beds, and sofas. RoSPA tracks several deaths a year in the UK from this alone. Either cut and convert to short separate cords, install cord cleats high on the wall to wind cords around, or replace with cordless blinds. Don't trust cleats placed at toddler-reachable height.

Cleaning products and medication. Bleach, dishwasher tablets (commonly mistaken for sweets), laundry pods, oven cleaner, multipurpose sprays. Move everything from under-the-sink to a high cupboard, or fit a magnetic child lock to the existing cupboard. Keep medications, vitamins, and supplements high and out of sight.

Button batteries. Small flat batteries from remote controls, car keys, novelty greeting cards, kitchen scales, hearing aids, slim toys. Swallowed, they cause severe alkaline burns to the oesophagus within two hours — preventable with prompt removal but devastating if missed. Tape closed any battery compartment that a child can open without a screwdriver. If you suspect ingestion, A&E immediately — don't wait, don't try to make them sick, don't try to look. Honey for an older child (>1 year) on the way to hospital can buffer the damage if more than 12 minutes have passed since suspected ingestion (NHS England guidance, 2022).

Stairs. A baby who can crawl can fall down stairs. Stair gates at top and bottom. The top gate must be screw-mounted to the wall, not pressure-mounted — pressure gates can give way under impact. Pressure gates are fine for the bottom and for room-to-room use.

Water. A baby can drown in 5 cm of water in seconds. Bath seats are positional, not safety devices. Never leave a baby alone in the bath — not for the doorbell, not for the phone, not to grab the towel from the airing cupboard. Empty paddling pools and bath tubs immediately after use. Garden ponds need fencing or covering until children are reliably much older. Toilets get a lid lock once mobile.

Room by Room

Living Room

• Wall-strap any furniture taller than the child's reach that could topple. TVs, bookcases, dressers. Even when "stable" — climbing toddlers apply force in unexpected places.
• Blind cords up high, on cleats or replaced.
• Corner protectors for sharp coffee tables and hearths if the room is open-plan. Foam ones are fine; the foamy industrial-style ones look uglier and are slightly more durable.
• Fireplaces — fixed guard around an open fire or a wood burner. Don't rely on screens that can be pushed over.
• Trailing cables and lamps with cords — secure behind furniture or use cord covers. Standard lamps tip easily.
• Plug sockets: modern UK sockets have a built-in safety shutter that is more effective than aftermarket plug-in covers; current RoSPA position is that plug-in covers can actually defeat the built-in shutter and are not recommended. Leave them alone.
• Heavy ornaments and remote controls with batteries off the coffee table, away from edges.

Kitchen

The kitchen is the highest-risk room in most houses.

• Locks or moves on under-sink cabinets containing cleaning products. Magnetic locks are excellent and toddler-proof for years; they don't change the cupboard's appearance.
• Medications, vitamins, supplements above the worktop, ideally in a locked box.
• Cooker: use back rings where possible. Turn pan handles to the back. A cooker guard is worth fitting if you have an exposed-front hob and a climbing toddler.
• Knives and scissors: in a high drawer with a child lock, or a magnetic strip on the wall above counter height. Drawer locks (the V-shaped ones that prevent the drawer opening more than a finger's width) are quick to fit.
• Hot drinks: set them in the centre of the table or counter, away from the edge. A toddler pulling a tablecloth-end produces a scald that's the leading cause of serious burns in under-fives. Drinks at "comfortable to drink" temperature — around 60°C — still scald a baby's skin in seconds.
• Bin lid: weighted or in a closed cupboard. Used coffee pods, chicken bones, small batteries from broken kit — bins contain a lot of swallowables.
• Kettles: at the back of the counter; coil the cord behind so it can't be pulled.
• Highchair: five-point harness, not just the lap belt; never leave a baby in a highchair unattended; use the harness even at home.

Bathroom

• Door closed by default; lever handles aren't toddler-proof, but a high spring-loaded latch or a doorknob lock is.
• Toilet lid lock once mobile — drowning hazard, also a contamination hazard.
• Bath: non-slip mat, set water heater to 48°C / 120°F or below so taps can't run scalding (this is one of the cheapest, most leveraged changes you can make). Run cold first, then hot, to avoid hot tap droplets in the path.
• Medication, mouthwash, perfume, razors, nail scissors, hair tools — all out of low cupboards. Mouthwash often has fluoride at higher concentrations than is safe for ingestion.
• Hair straighteners stay hot for ages after use; cool somewhere out of reach, never on the floor.

Bedrooms

• Cot: flat firm mattress, no bumpers, no pillows, no soft toys, no loose blankets — sleep bag at the right tog. Mattress at the lowest setting once they can pull up.
• Cot away from windows, blind cords, radiators, and curtains.
• Heavy items off the wall above the cot — pictures, mirrors, anything that could fall.
• Wardrobes anchored to the wall.
• Nightlight chosen for low light, not bright. LED, low-heat.
• Bed barriers when the toddler graduates to a single bed (around 2–3 years usually).

Garden, Garage, and Outside

• Garden gates with high latches. Reliably fastened.
• Pond covered or fenced until much older.
• BBQs supervised continuously when in use, kept out of reach for hours after — they stay hot.
• Garden chemicals (slug pellets, weed killer, lawn feed) locked, not in the shed where a child can wander in.
• Driveway access managed — ideally a fence or gate so a small child can't get out to the road. Reversing accidents in driveways are a recurring tragedy.

Stairs

• Top gate screw-mounted, bottom gate any type.
• Banister gaps wider than 6.5 cm — block with mesh or plexi panels.
• Carpet runner not loose, stair rods firm, no clutter on the stairs.

What Baby-Proofing Doesn't Replace

A few honest things:

• Active supervision is irreplaceable — particularly around water and in the kitchen.
• Hot drinks and toddlers don't mix. Move drinks immediately when they're around.
• Door locks between you and a wandering toddler at any moment when you can't see them are more useful than ten gadgets.
• Visiting other people's houses is where most accidents in the over-ones happen, because the proofing isn't there. A bag of basics — corner protectors, a couple of pressure gates, plug-in cooker locks, a roll of duct tape for awkward bits — travels well.
• Never assume the previous stage's setup still works. Reassess every couple of months as they grow.

A Two-Hour Walkthrough

If you're starting from scratch, this is the order that gets the most-leveraged things done first:

1. Wall-strap tall furniture and TVs (30 minutes)
2. Tie up or replace blind cords (15 minutes)
3. Move chemicals, medications, and button-battery devices to high storage (30 minutes)
4. Fit child locks on the cupboard with bleach in it and the drawer with knives (15 minutes)
5. Set the hot water heater to ≤48°C (5 minutes)
6. Stair gates at top and bottom (30 minutes if drilling top one)
7. Walk around the floor on your hands and knees, eye-level with a one-year-old. Pick up anything that fits through a toilet-roll tube (10 minutes — this last step usually surprises parents most)

Total spend: typically £50–150 depending on what you already have. Some local councils offer free baby-proofing kits for low-income families; worth asking.

The summary worth holding: most serious injury in small children is preventable with the same six or seven measures, applied early. The rest is supervision and reassessment as they grow.

Start at around five months, before they can move themselves. The injuries that put small children in A&E most often are: falls from height, poisoning from ingested cleaning products and medication, button battery ingestion, furniture and TVs tipping over, blind cord strangulation, and bath/pool drowning (which can happen in 5 cm of water in seconds). Each one is largely preventable with simple, cheap measures — wall-strap the bookcases, get rid of long blind cords, lock the cupboard with the bleach in it, tape closed any device with a button battery a child can reach. Re-do the walk-through at each new mobility stage: rolling, crawling, pulling to stand, cruising, walking, climbing. None of it replaces supervision — it lowers the cost of the moment supervision lapses, which it will.
