The classic story is almost identical in every paediatric A&E: a parent puts a hot drink down on a low coffee table, the toddler reaches up, the mug tips over the chest and shoulder. By the time the parent has the wet jumper off, the skin underneath is already red, blistering and starting to peel. They've never been more frightened in their lives.
Knowing exactly what to do in the first twenty minutes makes a measurable difference to how that injury heals — to how much it scars, whether it gets infected, and how much pain the child remembers. It's worth knowing now, not when you're standing in a kitchen with a screaming toddler in your arms.
Healthbooq provides paediatric burn first-aid and prevention guidance.
The single rule that matters most: 20 minutes of cool running water
If you remember nothing else from this guide, remember this: 20 minutes of cool (not cold) running water on the burn, started as soon as possible.
Why it matters: cooling for a full 20 minutes within the first three hours has been shown in multiple studies to reduce burn depth, reduce the need for skin grafts, and shorten healing time, even if you started cooling late. It is the most evidence-based intervention in paediatric burn first aid.
How to do it properly:- Use a tap, shower head, or large jug of cool tap water
- The water should be cool, not ice-cold — around 15°C is ideal. Iced water and ice are worse than nothing — they can cause additional cold injury, vasoconstriction, and hypothermia in a small child
- Run it gently and continuously over the burn for the full 20 minutes
- Yes, it's hard. Yes, the child will scream. Yes, do it anyway — wrap the rest of them in a dry warm towel and keep going
- Set a timer; people consistently underestimate how long 20 minutes feels
If the burn is on the face or a part of the body that doesn't fit under a tap, soak a clean cloth in cool water and keep replacing it (don't leave a cooling cloth on — it warms within seconds).
Before the cooling: stop the burning
Before water touches the burn, stop the heat source.
- Hot liquid spilled on the body — get the wet clothing off the child within seconds. Wet fabric holds heat against the skin and prolongs the burn. Cut clothes off if they're stuck rather than pulling.
- Don't try to peel off clothing that has melted onto the skin — leave it; cool the burn through the fabric.
- Flame burns — drop, roll, smother with a coat or blanket
- Chemical burns — flush with water for at least 20 minutes; remove contaminated clothing while you flush
- Electrical burns — disconnect the power source before touching the child
Remove watches, bracelets, nappies and tight clothing near the burn before swelling sets in.
After the 20 minutes: cover and seek advice
Once you've cooled for the full 20 minutes:
Cover the burn with cling film (Glad Wrap / Saran Wrap):- Discard the first metre on the roll (it's not sterile)
- Lay the film lengthwise along the limb in long strips — do not wrap it tightly around an arm or leg, because the limb will swell
- Cling film is preferred because it doesn't stick, keeps the wound clean, and lets clinicians see the burn without removing a dressing
- For face burns, use a clean damp cloth instead of cling film
Then keep the child warm — small children lose heat fast, and a chilled child is a sicker child. Wrap the rest of them in a blanket; the burn area stays under cling film, the body stays warm.
Pain relief:- Paracetamol or ibuprofen at the correct weight-based dose
- Don't use creams, butter, toothpaste, egg whites, aloe straight from the plant, "burn sprays," or any home remedy. They trap heat, they cause infection, and they make the burn harder to assess
- Don't pop blisters
When to seek medical care — and how urgently
Call 999 / go straight to A&E for:- Any burn larger than the child's hand (palm + fingers ≈ 1% of body surface)
- Burns on the face, hands, feet, genitals or across a joint
- Burns that go all the way around a limb (circumferential)
- Any burn that looks white, waxy, leathery, brown or charred
- Any burn from electricity, fire or chemicals
- Any burn in an under-five with significant blistering
- Any sign of inhalation: hoarse voice, soot around nose or mouth, coughing, stridor
- Burns to a baby under one
- Smaller superficial burns with redness and minor blistering
- Sunburn covering a large area or with blistering
- Anything you're not sure about
A burn that looks small and red right after the injury can blister and deepen over the next 24–48 hours. If a "minor" burn is getting worse, go in.
What you'll see — and what it means
You don't need to grade burns like a clinician, but a rough mental map helps:
- Red, dry, painful, no blisters — superficial. Heals in days, no scarring.
- Red, blistering, weeping, very painful — partial-thickness. Needs proper dressing care; may scar; medical review needed.
- White, waxy, leathery, painless or oddly numb — full-thickness. Always emergency.
The painless burn isn't a less serious one. Full-thickness burns destroy nerves, so the worst burns can hurt the least at the centre — usually with painful partial-thickness skin around the edges.
Scalds — the most common burn by far
Most paediatric burns in the UK are scalds, mostly to under-twos, mostly from:
- A pulled-down mug of hot tea or coffee
- A reached-up bowl of hot soup or instant noodles (the worst — they scald and stick)
- Bath water that's too hot
- A kettle or saucepan handle within reach
The temperature math is sobering. Hot water at 60°C — the default for many uninsulated UK hot-water systems — causes a full-thickness burn in young skin in about five seconds. At 55°C it takes about 30 seconds. At 50°C, several minutes. Lowering your hot-water cylinder is the single best burn-prevention move you'll ever make.
Prevention — the high-impact list
In rough order of impact:
- Set the hot-water cylinder thermostat to ≤48°C, or fit a thermostatic mixing valve on the bath tap
- Test bath water with the inside of your wrist or elbow before the child goes in — aim 37–38°C
- Hot drinks at the back of the worktop, never on a low coffee table or on the arm of a sofa
- No drinking hot tea while holding the baby — the classic scald scenario
- Pan handles turned inwards on the hob; back rings preferred
- A hob guard on a kettle/hob accessible to a climbing toddler
- Curly cord on the kettle, well back from the worktop edge — kettles get pulled down by their cords more than by their handles
- A safety gate on the kitchen door for crawling and toddler ages
- Glass-fronted fires and wood burners — a fixed nursery fireguard, not just one perched on the hearth
- Hair straighteners can hit 220°C — they stay too hot to touch for half an hour after unplugging. Out of reach, then put away
- Smoke alarms in every level of the house, tested monthly
Special cases
Sunburn. Apply cool compresses, paracetamol/ibuprofen for pain, plenty of fluids, after-sun lotion. Seek medical advice for blistering sunburn or sunburn in a child under one. Severe sunburn in childhood materially increases lifetime melanoma risk.
Electrical burns. The visible skin burn often looks small while the deeper tissue and muscle damage is significant. Always go to A&E, even if the child seems fine — the cardiac and deep-tissue effects can be delayed.
Tongue and mouth burns from hot food (instant noodles, microwaved nuggets). Cool with sips of cold water or ice lollies, paracetamol for pain, soft cool foods for a day or two. See a doctor if the child can't drink or has signs of swelling in the throat.
Friction and rope burns are treated like burns — cool, cover, seek advice for anything more than superficial.
Healing and scarring
Burn wounds heal best kept clean, moist (under appropriate dressings) and protected. Once healed, the new skin:
- Stays sensitive for weeks to months
- Burns in the sun extremely easily — high-factor sunscreen and clothing cover for at least a year
- Can scar — silicone gels and sheets reduce visible scarring with consistent use over months
- Can itch as it heals; antihistamines and moisturiser help
Significant scarring on visible areas warrants a referral to a paediatric plastic surgery team — the NHS has well-established paediatric burn services in major children's hospitals.
The principle
When a burn happens, your three minutes of preparation today saves you from indecision in a kitchen full of screaming and steam:
- Stop the burning — clothes off, source removed
- Cool with cool running water for a full 20 minutes — set a timer, keep the rest of the child warm
- Cover with cling film lengthwise, give pain relief
- Decide where to go — A&E for big, deep, facial, hand, foot, genital or under-one burns; 111 for the rest
Everything else is detail.
Key Takeaways
Most childhood burns are scalds — hot tea, hot water, instant noodles — and they happen in the kitchen or at the dining table to under-twos. The single most important first-aid action is twenty minutes of cool (not ice-cold) running water on the burn, started as soon as possible and continued the full twenty minutes even if the child resists. After cooling, cover with cling film (lengthwise, not wrapped tightly), give pain relief, and seek medical advice for any burn larger than a 50p coin, any burn on face/hands/feet/genitals/joints, any blistering burn in a child, and any burn that looks waxy, white or charred.
