Most Common Injuries Among Babies and Toddlers and How to Prevent Them

Bumps, scrapes and the odd tumble are part of growing up. You can’t wrap your child in cotton wool, and trying to will only exhaust you both. But there’s a real difference between the ordinary bruises of active childhood and the kind of serious, often preventable injuries that send babies and toddlers to A&E or, in the worst cases, prove fatal.

Unintentional injury remains one of the leading causes of death in young children in both the UK and the US, and the same handful of causes come up again and again: falls, burns and scalds, choking and suffocation, drowning, poisoning, and road accidents. The reassuring part is that almost all of these are preventable once you understand how and where they happen.

Prevention really comes down to two things working together. The first is preparation: getting your home genuinely childproofed before your child needs it, not after a near miss. The second is supervision: being physically present and paying attention, particularly around water, stairs, and roads, where seconds matter. Phones down, eyes up.

Accidents will still happen even to careful, attentive parents, so it helps to know basic first aid alongside prevention. Below are the injuries that come up most often, what tends to cause them at each age, and what actually reduces the risk.

Falls

Falls are the single most common reason young children end up in emergency departments, more common even than the ones parents worry about most. Babies fall off changing tables, beds and sofas. Toddlers fall down stairs, out of highchairs, off furniture they’ve climbed, and from windows.

Once a baby can roll, at around four to six months, they can go over the edge of anything they’re placed on. Once they’re mobile, the risks change again, climbing onto chairs, pulling up on unstable furniture, and going up and down stairs before they’re steady on their feet.

Prevention: Never leave a baby unattended on a changing table, bed or sofa, not even for the few seconds it takes to grab a nappy. Use stair gates at the top and bottom of staircases once your baby starts crawling. Anchor tall or heavy furniture, bookcases, chests of drawers, wardrobes, to the wall, since toppling furniture is a genuine and often underestimated hazard for climbing toddlers. Fit window locks or restrictors on upstairs windows, and keep cots, chairs and other climbable furniture away from windows. If you use a highchair, always use the harness, every single time, even for a quick snack.

Burns and scalds

Hot drinks are one of the most common causes of scalds in under-fives, along with bath water that’s too hot and contact with hobs, ovens, irons and curling tongs. A toddler’s skin is thinner than an adult’s, so it burns more quickly and at lower temperatures.

Prevention: Keep hot drinks well out of reach, not just off the edge of the table but somewhere your toddler genuinely can’t grab or pull down, and never hold your baby while drinking something hot. Turn pan handles inward on the hob and use the back rings where you can. Check bath water with your hand or a bath thermometer before putting your baby in, and consider fitting a thermostatic mixing valve so the water can’t run scalding hot. Keep straighteners, curling tongs and irons unplugged and out of reach even after use, since they stay hot for several minutes.

Choking

Choking is a particular risk between around six months, when babies start on solid food, and three years old, when they’re still learning to chew properly and love putting small things in their mouths. Foods like whole grapes, nuts, popcorn and hard sweets are common culprits, alongside small toy parts, coins, and button batteries.

Prevention: Cut round or firm foods like grapes, cherry tomatoes and sausages into small pieces, and avoid whole nuts and hard sweets under the age recommended by your health visitor. Keep small toys and toys with small removable parts away from babies and toddlers, and be especially careful if you have older children whose toys have small pieces. Button batteries deserve special mention: they’re in remote controls, watches, singing greeting cards and small toys, and if swallowed they can cause serious internal damage within hours. If you suspect your child has swallowed one, treat it as a medical emergency and go to A&E straight away rather than waiting to see if symptoms appear. It’s worth doing a baby and child first aid course so you know exactly what to do if choking happens, since talking through it in an article is no substitute for practising the technique.

Suffocation and safe sleep

Suffocation risk is highest for babies during sleep, which is why safe sleep guidance exists and is worth following closely rather than treating as optional. A cot should be kept clear: no pillows, no duvets, no cot bumpers, no soft toys, and no loose blankets for young babies. A fitted sheet and, if needed, a well-fitted baby sleeping bag is genuinely all that’s required.

Prevention: Always put your baby down on their back to sleep, in their own cot or Moses basket, in the same room as you for at least the first six months. Bed-sharing carries a higher risk of accidental suffocation, particularly if you or your partner smoke, have been drinking alcohol, are taking medication that makes you drowsy, or your baby was born prematurely or at a low birth weight. If you do want to bed-share, talk to your midwife or health visitor about how to reduce the risk as much as possible, since they can go through your specific circumstances. Also be mindful of blind cords, which pose a strangulation risk, and keep cots away from them.

Drowning

Drowning statistics are genuinely sobering, and what surprises a lot of parents is that it’s not usually swimming pools where it happens closest to home. A small child can drown in just a couple of inches of water, which means baths, paddling pools, garden ponds and even buckets are real hazards, not just the obvious ones like rivers and swimming pools.

Prevention: Never leave a baby or toddler alone in the bath, even for a moment, and never leave an older sibling in charge of watching them. Empty paddling pools and buckets straight after use rather than leaving them standing. Fit a toilet seat lock if your toddler is curious about the toilet. If you’re near a pool, lake or the sea, stay within arm’s reach and keep your attention on your child rather than your phone or a conversation, since drowning is often silent and quick, not the loud splashing you might expect. Swimming lessons from an early age are a great idea and build water confidence, but they don’t make a child drown-proof, so supervision still matters just as much.

Poisoning

Toddlers explore the world by putting things in their mouths, and that includes medicines, cleaning products, cosmetics and even things like dishwasher tablets, which look bright and sweet-like to a curious child. Poisoning accidents spike once a child is mobile and can reach cupboards or bags.

Prevention: Store medicines and cleaning products up high, out of sight and out of reach, ideally in a locked cupboard, rather than relying on child-resistant caps alone, since toddlers are more capable than people expect. Keep products in their original containers so you know exactly what they are if there’s ever an incident. Be careful with visitors’ bags and coats too, since medication is often kept in handbags at exactly toddler height on the floor. If you think your child has swallowed something they shouldn’t have, contact your GP, NHS 111, or your local poison control line straight away rather than waiting for symptoms.

Car accidents

Every car journey carries some risk, and a correctly fitted, age and size appropriate car seat is one of the most effective things you can do to protect your child. Fitting mistakes are common, so it’s worth getting your seat checked by a trained fitter, many retailers and some local councils offer this free of charge.

Prevention: Use a car seat that matches your child’s current height and weight rather than just their age, and keep rear-facing for as long as the seat allows, since this offers better protection for the head and neck. Children should stay in a booster seat until the adult seatbelt fits them properly on its own, which for most children isn’t until they’re around 135cm tall or roughly 12 years old, though this varies by law depending on where you live, so it’s worth checking your local guidance. Keep children in the back seat, and resist the pleading to sit in the front, no matter how convincing the argument.

A word on first aid

Knowing what causes these injuries is only half the picture. The other half is knowing what to do in the first minute or two if something does happen, because that’s often what makes the biggest difference to the outcome. A short baby and child first aid course, run by organisations like St John Ambulance or the British Red Cross, covers choking, CPR, burns and bumps to the head, and gives you the muscle memory to act quickly rather than freeze. It’s a few hours well spent, and most parents come away saying they wish they’d done it sooner.

If you’re ever genuinely unsure whether an injury needs medical attention, it’s always better to call your GP, NHS 111, or take your child to be seen. Trust your instincts. You know your child better than anyone, and no one will think less of you for getting something checked that turns out to be minor.
