A child explores by mouth from about four months until they're three or so. Almost everything a small child gets injured by at home falls into a short, predictable list — and it's worth knowing that list rather than treating every object as suspect. The drawer of cooking spoons isn't a hazard; the magnet on the fridge, the lithium cell in the kitchen scale, and the dishwasher tablet under the sink are.
Below is the focused version: what actually injures children, where it lives, and what to do about it.
Healthbooq provides practical guidance for identifying and managing household hazards.
The high-stakes short list
These are the items most likely to cause serious or fatal injury and deserve specific countermeasures rather than general "store safely" advice.
Button and coin cell batteries (CR2032 etc.). A 20mm lithium cell lodged in a child's oesophagus generates an electrolytic burn that can erode through the wall and into the aorta within two hours. They live in: car keys, kitchen scales, bathroom scales, remote controls, tea-light candles, hearing aids, fitness bands, musical greeting cards, watches, thermometers. Tape over every battery compartment that has a child-accessible cover. Keep loose batteries in a locked drawer. If ingestion is suspected: A&E immediately, do not wait for symptoms, and ask about honey en route (UK and US guidance: 10 ml of honey every 10 minutes for children over 12 months delays the burn).
High-power magnets (rare-earth / neodymium). Sold as fidget toys, magnetic stars, jewellery. Two or more swallowed magnets attract through bowel walls and perforate. Banned for sale as toys in several countries; still circulate. Out of the house if you have a child under five, full stop.
Paracetamol and ibuprofen. The most-swallowed medications in young children. A 10 kg toddler reaches a hepatotoxic paracetamol dose at fewer tablets than parents expect. Liquid forms are sweet and palatable. Move all painkillers — including yours — above 1.5 m, behind a latch, in original child-resistant packaging.
Dishwasher tablets and laundry capsules. The pods are the worst offenders: they squirt concentrated detergent on contact, and concentrated alkali burns oesophagus and eye in seconds. Tablets sit in the loading drawer, which is at toddler eye level. Move both above 1.5 m. Don't load the dispenser until you're about to run the cycle.
Looped blind and curtain cords. Strangulation deaths from looped cords are well documented. Cleat the cord, cut it, or replace with cordless. Move cots away from windows. Relevant standards: BS EN 13120 (UK), ANSI/WCMA A100.1 (US).
Choking-size foods. Whole grapes, hot dogs / sausage rounds, hard sweets, popcorn, whole nuts (especially peanuts), large chunks of raw apple or carrot. The worst combination is a round, slick shape that exactly matches the airway diameter — so grapes get quartered lengthwise, hot dogs get cut lengthwise then chopped, and whole nuts wait until age four.
Hand sanitiser and alcohol. Often missed. A 60% ethanol gel in a toddler-friendly bottle is a poisoning risk; a swig from a glass left on a coffee table can cause hypoglycaemia and seizures in a small child. Out of reach, lid on, glass cleared.
Liquid nicotine / e-cigarette refills. A single refill bottle contains enough nicotine to kill a toddler. Lock these up like medication.
Grandparents' handbag. When a grandparent visits, the bag is the highest-risk object in the house for the next few hours. It contains heart medication, antihypertensives, anticoagulants, glasses, mints (often choking-size), pen caps, button batteries, hand sanitiser, lipsticks. The bag goes on a high shelf when the grandparent walks in. Talk to them about it before the visit.
Choking risks — the toilet-roll test
The classic test: if it fits through the cardboard tube of a toilet roll, it can lodge in a small child's airway. Use the test on toys and on toy parts.
Most-mistaken items in this category:
- Coins, especially £1 / quarter-sized — common between sofa cushions
- Hair-ties and rubber bands — get stuck around things
- Pen caps — designed with airway holes for a reason
- Lego, beads, marbles, dice — siblings' toys
- Pet kibble — the dog bowl is a buffet for a crawler
- Single small fridge magnets
- Earplugs and earphone tips
Items that mostly need up, not locks
These cause less catastrophic but still real injury: cuts, falls, scalds.
- Knives, scissors, razors — drawer with a latch, or top drawer.
- Glass and ceramics — out of reach when set down to cool, not on a low side table.
- Hot drinks — tea or coffee stays hot enough to scald for 15 minutes; the most common burn cause in babies is a parent's mug. Don't hold a baby and a hot drink. Don't put one on a low table near a cruiser.
- Plastic bags, dry-cleaning bags — knot and bin, don't store.
- Cosmetics, nail varnish, perfume — not lethal but cause significant mouth and eye irritation. Out of reach.
What to actually do — by storage rule
The simplest, most effective rule:
- High and locked: medicines, cleaners, dishwasher tabs, hand sanitiser, batteries, e-liquid, alcohol. Above 1.5 m and behind a latch.
- Cleated, cut, or replaced: looped blind cords.
- Up off the floor when the baby is around: small parts, coins, hair-ties, anything that passes the toilet-roll test.
- Anchored to the wall: top-heavy furniture (separate hazard, see furniture tip-overs).
- Original containers, original labels. Re-bottling cleaning products into drinks bottles is a classic and lethal mistake.
The cleaning cupboard under the kitchen sink is a special case: even with a child latch, this is the single most common ingestion site. Move products out of it. The latch is a backup, not a primary safety system.
What to do if you suspect ingestion
- In the US: Poison Control 1-800-222-1222.
- In the UK: NHS 111 for advice; 999 / A&E if symptoms (drooling, refusal to swallow, vomiting blood, unsteady, drowsy, breathing trouble) or for any suspected button battery.
- Always: bring the bottle or packet with you. Don't make the child vomit. Don't give milk unless told to.
- Specific to button batteries: A&E immediately, even with no symptoms — and honey 10 ml every 10 minutes en route (children over 12 months only).
Re-walk the house every few months
Capability changes faster than you adjust to it. The medicine on the bedside table was fine at 6 months and a problem at 14. The chair pulled up to the kitchen counter is now a stepladder. After every developmental step (rolling, crawling, pulling up, walking, climbing), do another floor-level walk-through and a counter-level one. Every three months is plenty.
Key Takeaways
A small set of items causes most of the serious accidents in young children: button batteries, high-power magnets, paracetamol/ibuprofen, dishwasher tablets and laundry pods, blind cords, and choking-size foods (whole grapes, hot dogs, hard sweets, peanuts). Get those locked, cleated, or off the floor and you've handled most of the avoidable injuries. Hand sanitiser, e-cigarette refills, and grandparents' handbags are easy to miss but high-risk.
