When you think of household hazards, things like cleaning products, sharp corners, or hot pans probably spring to mind. But there’s another danger that’s easy to overlook - and it could be sitting quietly inside everyday items all around your home.
We sat down with Katrina Phillips OBE, Chief Executive of the Child Accident Prevention Trust (CAPT), and mum-of-two Hollie Phillips, whose little boy Ralphie almost lost his life after swallowing a button battery.
This story isn’t easy to hear - but it could save a child’s life.
“I thought he’d swallowed a Cheerio…”
Hollie is a childcare professional with years of experience and all her first aid training under her belt. She knows the dangers of button batteries - or so she thought.
The day before her son Ralphie’s first birthday, he suddenly became very unwell. “He was dribbling loads, pushing away his bottle, and turning a strange grey colour,” Hollie recalls. “Everyone said he was teething, but something in my gut told me this wasn’t right.”
At first, doctors thought Ralphie might have swallowed something sharp. He was sent home with paracetamol. But hours later, he was vomiting black, blood-stained fluid - a terrifying sight that led Hollie to call 999.
By the time Ralphie reached Addenbrooke’s Hospital, doctors discovered the cause: a button battery lodged in his oesophagus. Within minutes, he was rushed into emergency surgery.
“I remember thinking, ‘My son is going to die,’” says Hollie. “It all happened so fast. We didn’t even know where the battery had come from.”
What happens when a child swallows a button battery?
As Katrina explains, a button battery might look harmless - shiny, round, and no bigger than a 5p coin - but once it’s swallowed, it can cause catastrophic internal burns.
“When a button battery gets stuck inside a child’s food pipe, it starts reacting with their bodily fluids,” she says. “It creates the same effect as caustic soda - essentially burning through the flesh.”
In some cases, it can take just two hours for a battery to cause fatal damage. If it burns through to a major artery, the outcome is often tragic.
It’s horrifying to imagine - and even more shocking when you realise how many of these batteries are hidden in everyday items.

Where are button batteries hiding?
Most of us think of button batteries being used in small toys - and assume modern toys are safe because they come with screws and secure battery covers.
But Katrina warns that button batteries are everywhere.
“You’ll find them in remote controls, car key fobs, kitchen and bathroom scales, digital thermometers, fitness trackers, hearing aids, light-up decorations, and even musical greeting cards,” she says. “They’re also in novelty items like flashing wands, LED tea lights, and children’s light-up shoes or jumpers - especially around Halloween, Bonfire Night and Christmas.”
In other words, even the most careful parents might have button batteries within reach without realising.
Hollie later discovered Ralphie’s battery had likely fallen out of an old toy belonging to her eldest child. “It must have dropped out years ago,” she says. “The battery was dead when they found it - and that’s probably what saved his life.”
The symptoms to look out for
Because button battery injuries happen inside the body, the signs can be subtle - and often mistaken for teething or a tummy bug.
Hollie’s key warning signs were:
- Excessive dribbling (more than normal teething)
- Arching of the back or signs of pain in the chest/stomach
- Pale or grey skin
- Refusing food or drink
- Vomit that looks dark or smells acidic or metallic
Katrina adds that some children don’t vomit at all. “They may just seem off-colour, clingy, or point to their throat or chest,” she explains. “If you suspect your child has swallowed a button battery - even if you didn’t see it happen - go to A&E immediately or call 999.”
And remember: don’t give your child food, drink, or make them sick. The battery’s chemical reaction can worsen with fluid.
A miracle recovery
After emergency surgery, Ralphie spent his first birthday on life support. “We thought we’d be home by the weekend,” Hollie says. “But it was nearly three weeks before we left hospital. He had to be fed through a tube, and it took months of reconstructive surgery to repair the damage.”
Today, Ralphie is a happy, healthy little boy - a miracle, as his doctors call him. “He’s here for a reason,” Hollie says. “I’m using my voice because he couldn’t use his. If sharing our story stops just one family going through what we did, it’s worth it.”
Prevention starts at home
As both Hollie and Katrina agree, awareness is everything. Button battery injuries are 100% preventable - if we know what to look for.
Here’s what every parent and carer can do:
- Check your home. Walk around and make a list of anything that might contain a button battery - including decorations, gadgets, and bathroom items.
- Test for safety. Toys should meet UK safety standards and have a screw-secured battery compartment. Avoid cheap, unbranded toys that don’t.
- Store spares safely. Keep new and used button batteries in a sealed container, out of children’s reach and sight. Even “dead” batteries can still cause severe burns.
- Check before you buy. Be alert when buying gifts. Look out for easy-access batteries or spare ones included in the packaging.
- Spread the word. Share this message with friends, family, and anyone who looks after your children. The more people know, the more lives we can save.
As Katrina puts it: “The question I always ask is - button batteries, where are yours?”
“Trust your gut”
If there’s one thing Hollie wants every parent to take away, it’s this: trust your instincts.
“You know your child better than anyone,” she says. “If something doesn’t feel right, even if everyone tells you it’s fine, listen to that little voice inside. It might just save their life.”
Button battery safety might not be something you think about every day - but after hearing Ralphie’s story, it’s impossible to ignore.
Please, take a few minutes today to check your home. Share this article with your friends. And help us spread the word about a hidden danger that no family should ever have to face.
Because when it comes to child safety, a little awareness goes a very long way.
