Medicines, cleaning products, liquid laundry capsules, and button batteries are the everyday home dangers behind child poisonings. A swallowed button battery is a 999 emergency.
Thousands of young children are seen in UK hospitals each year after swallowing or touching something poisonous at home. The biggest risks are medicines, cleaning products, liquid laundry capsules, e-cigarette refills, and button (coin-cell) batteries. Button batteries are the most urgent: if swallowed, they can burn through a child's throat in as little as two hours.
Young children explore by putting things in their mouths and cannot tell a sweet from a pill or a drink from a cleaning fluid. Brightly coloured liquid laundry capsules and vape refills are especially attractive. Button batteries — found in toys, remote controls, car keys, thin electronics, and greetings cards — react with saliva and generate a caustic current that burns internal tissue, causing catastrophic injury with few early symptoms.
In your child's behaviour
Store hazards up, away, and locked
Keep medicines, cleaning products, liquid laundry capsules, and vape refills up high, out of reach and out of sight, ideally in a locked or child-resistant cupboard. Child-resistant does not mean child-proof — it only buys time.
Treat button batteries as high-risk
Keep spare button batteries in a sealed container out of reach, and check that toys, remotes, and gadgets have battery compartments secured with a screw. Dispose of used batteries safely — a 'flat' battery can still injure.
Know who to call before you need to
Save NHS 111 and 999 where you can find them fast. For a swallowed button battery, do not wait to see if symptoms appear — act immediately.
In immediate danger: call 999. For non-emergency police matters, call 101.

Myth: A used or nearly dead button battery is no longer dangerous to swallow.
Fact: Great Ormond Street Hospital and CAPT are clear that a used battery can still discharge enough charge to burn tissue, so every button battery, new or old, needs to be kept safely away from children and disposed of properly.
Myth: If my child seems completely fine after swallowing a battery or something poisonous, it probably was not serious.
Fact: GOSH and CAPT both warn that injury from a swallowed button battery can develop before obvious symptoms appear, which is exactly why the advice is to go straight to A&E or call 999 the moment you suspect a swallow, rather than waiting to see how the child seems.
Myth: Making a child sick brings a swallowed poison back up before it can do harm.
Fact: Guidance for both button batteries and other poisoning is not to try to make a child vomit, since this can cause further injury on the way back up and does not reliably remove what was swallowed.
Toddlers explore the world by putting things in their mouths, and this is the age when medicines, cleaning products, and small button batteries in toys, remotes, and key fobs are most likely to be reached and swallowed. Store hazards locked and out of sight rather than just out of reach, since a determined toddler can climb.
A child this age can start to understand simple rules, such as medicine is not sweets and a shiny battery is not a toy, and can be taught to tell an adult straight away if a battery has fallen out of something or if they or a friend has swallowed or touched anything they should not have. They should not yet be relied on to keep themselves safe without locked storage doing the real work.
