My Child Swallowed a Coin or Small Object — What Should I Do?
It can happen incredibly quickly.
Your toddler is playing happily.
You look away for a moment.
Then a coin, bead, or small toy part on the floor has disappeared.
Your child points towards their mouth.
Perhaps they cough once.
And suddenly you are asking:
“Have they swallowed it?”
The reassuring news is that many small, blunt objects that reach the stomach pass naturally through a child's digestive system without causing harm. NHS hospital guidance confirms that coins, small plastic items and small toys commonly pass without intervention. Leeds Teaching Hospitals NHS Trust
But there is an important exception.
Some swallowed objects can cause serious injury even when a child initially appears completely well.
In particular:
BUTTON BATTERIES and MAGNETS need urgent medical assessment.
So the first question is not simply:
“Did my child swallow something?”
It is:
“WHAT did they swallow?”
First: is my child choking?
Swallowing and choking are not the same thing.
If an object has passed through the throat into the oesophagus—the food pipe—the child may still be breathing normally.
If an object blocks the airway, however, the situation changes immediately.
A child who is coughing loudly can usually still move air. Encourage them to continue coughing and stay with them.
But if your child is unable to breathe properly, becomes silent, cannot cough effectively or develops blue or abnormal colouring:
Call 999 immediately and begin appropriate choking first aid.
Do not blindly put your fingers into the child's mouth looking for an object you cannot see. NHS parent guidance warns that doing this can push an object further in. West Yorkshire Healthier Together
What happens after a child swallows an object?
A swallowed object can take several routes.
It may:
pass into the stomach
remain stuck in the oesophagus
or, less commonly, enter the airway rather than the food pipe.
That distinction explains why symptoms matter.
An object lodged in the oesophagus can cause:
- drooling
- difficulty swallowing
- refusing food or drink
- gagging or retching
- pain in the throat or chest.
An object entering the airway may produce:
- sudden coughing
- noisy breathing
- breathing difficulty
- a new change in voice.
Current Alder Hey Children's NHS Foundation Trust guidance includes drooling, respiratory symptoms, new cough or voice change, choking with eating/drinking, food refusal, gagging and vomiting among warning features after a suspected ingestion. Alder Hey Children's Hospital Trust
My child swallowed a coin. Should I panic?
Coins are among the most commonly swallowed objects in childhood.
If a small coin passes into the stomach, it will often continue through the digestive tract naturally.
However, a coin can sometimes become lodged in the oesophagus.
So do not judge the situation purely by the size of the coin.
If your child develops:
drooling
difficulty swallowing
persistent vomiting
chest/throat pain
refusal to eat or drink
or
breathing symptoms
they need medical assessment.
If you are unsure what was swallowed or where it has gone, seek clinical advice.
Does every swallowed coin need an X-ray?
Not necessarily.
Whether imaging is needed depends on the object, symptoms and clinical assessment.
X-rays can usually identify metallic objects, but many plastic objects cannot.
Leeds Teaching Hospitals NHS guidance notes that not every swallowed foreign body requires investigation and that many objects are not visible on X-ray. Leeds Teaching Hospitals NHS Trust
So an X-ray is a clinical tool—not simply a routine requirement whenever something disappears into a child's mouth.
What if my child swallowed a button battery?
This is an emergency.
Button batteries are the small, flat, circular batteries found in everyday household objects such as:
car-key fobs
remote controls
hearing aids
small toys
digital scales
and some cards or electronic devices.
If a button battery becomes stuck in the oesophagus, an electrical reaction can cause severe tissue injury.
And critically:
Your child may initially have few or no obvious symptoms.
GOSH advises parents not to wait for symptoms if a button battery may have been swallowed. GOSH Hospital site
If you know or suspect that your child has swallowed a button battery, go straight to A&E.
Do not wait to see whether it passes.
Do not deliberately make your child vomit.
Do not delay leaving home while searching extensively for the missing battery.
If the battery packaging or the device it came from is immediately available, take it with you—but do not delay getting to hospital to find it. GOSH Hospital site
Why can a “flat” battery still be dangerous?
Parents sometimes assume an old or “dead” battery is harmless.
Don't make that assumption.
GOSH specifically warns that batteries considered flat or dead can still cause injury if swallowed. GOSH Hospital site
So:
Missing button battery + possible ingestion = emergency assessment.
What if my child swallowed a magnet?
Magnets also deserve particular attention.
Modern small, powerful magnets can attract one another through loops of bowel.
If more than one magnet is swallowed—or a magnet is swallowed with another metal object—they can trap tissue between them and cause serious internal injury.
Alder Hey advises parents to attend A&E if a child is suspected of swallowing any magnets. Alder Hey Children's Hospital Trust
Do not wait for tummy pain.
A child can initially appear well.
What about a sharp object?
Sharp or pointed objects also require urgent assessment.
Examples might include:
- pins
- needles
- screws
- fragments of hard material
- sharp toy components.
NHS Healthier Together guidance places swallowed large or sharp objects among situations requiring urgent hospital assessment. West Yorkshire Healthier Together
Do not attempt to push a suspected sharp object down by giving large amounts of food.
Seek medical advice.
Should I make my child vomit?
No.
Do not deliberately make a child vomit after swallowing a foreign object.
Bringing the object back through the oesophagus can potentially cause further problems.
This is particularly important with button batteries and sharp objects.
Follow the advice given by the emergency or poison/medical service managing your child's specific situation.
Should I give my child food or drink?
This depends on what has been swallowed and whether urgent removal might be required.
If you suspect a button battery, GOSH advises against giving food or drink while you take the child for emergency assessment. GOSH Hospital site
For an ordinary low-risk object that has already been medically assessed and is believed to have passed into the stomach, advice may be different.
Do not assume the same rule applies to every swallowed object.
Should I search through my child's poo?
Usually not.
Parents understandably want proof that the coin or toy has passed.
However, current NHS hospital guidance says that routinely searching through a child's stools is generally unnecessary and unhelpful. Leeds Teaching Hospitals NHS Trust
If clinicians ask you to monitor the passage of a particular object, follow their instructions.
How long can an ordinary object take to pass?
Healthier Together states that many uncomplicated swallowed objects pass through the digestive system in approximately 3–5 days. Healthier Together
But this is not a reason to watch and wait with a:
battery
magnet
large object
sharp object
or a symptomatic child.
Those are different scenarios.
My child seems completely fine. Can something still be wrong?
Yes—and this is particularly important with button batteries.
A child can initially appear relatively well despite a potentially dangerous ingestion.
That is why management depends partly on what the object is, rather than simply how the child looks.
If a button battery or magnet is missing and ingestion is possible, do not wait for:
pain • vomiting • drooling • breathing difficulty.
Seek urgent assessment.
What happens in hospital?
The clinical team will ask:
What was swallowed?
When did it happen?
How large was it?
Could there have been more than one?
Does the child have symptoms?
Imaging may be required.
For suspected button-battery ingestion, GOSH explains that an X-ray is commonly used to determine the battery's location and approximate size. GOSH Hospital site
If an object is lodged in the oesophagus or poses a significant risk, it may need to be removed with an endoscope while the child is appropriately anaesthetised.
Not every swallowed object requires an operation.
Is this an ENT problem?
It can be.
Foreign bodies high in the throat, airway or upper oesophagus may involve ENT and other paediatric specialist teams.
Depending on where the object is located, management may involve:
Emergency Medicine • Paediatrics • ENT • Paediatric Surgery • Gastroenterology
rather than one speciality alone.
The priority is getting the child to the appropriate emergency service, not trying to choose the specialist yourself.
When should parents seek urgent help?
Go to A&E urgently if your child has swallowed—or may have swallowed:
- a button battery
- a magnet
- more than one magnet
- a sharp object
- a large object
- an object whose nature you cannot safely identify and there are concerning symptoms.
Also seek urgent assessment if your child develops:
- choking
- difficulty breathing
- noisy breathing
- excessive drooling
- inability or reluctance to swallow
- repeated gagging or retching
- vomiting
- significant throat, chest or abdominal pain
- blood in vomit or stool
- marked drowsiness or appears significantly unwell.
These warning features are consistent with current UK paediatric safety-netting guidance. West Yorkshire Healthier Together
If your child cannot breathe properly, call 999.
Preventing swallowed objects at home
Young children explore with their mouths.
Prevention therefore matters.
Pay particular attention to:
remote controls
car keys/key fobs
musical cards
hearing-aid batteries
small electronic toys
loose batteries
magnetic construction toys
and older siblings' small toys.
Battery compartments should be securely closed.
Keep spare—and used—button batteries completely out of children's reach.
Be especially cautious with small high-powered magnetic balls. Alder Hey Children's Hospital Trust
Swallowed objects in children across London and Essex
If your child has swallowed something, the useful sequence is:
WHAT was it? → Are they BREATHING? → Are they SWALLOWING? → Battery/magnet/sharp object?
Mr Gaurav Kumar, Consultant ENT Surgeon, assesses children with paediatric ENT, airway and swallowing-related problems across London, East London, Romford, Ilford, Redbridge, Brentwood, Chelmsford and surrounding areas of Essex.
Suspected dangerous foreign-body ingestion belongs in urgent/emergency care, not a routine ENT appointment.
The key message for parents
Most small, blunt objects that successfully reach the stomach pass naturally.
But never apply that reassurance to every swallowed object.
Remember:
BUTTON BATTERY = A&E NOW
MAGNET = A&E
SHARP/LARGE OBJECT = URGENT ASSESSMENT
CAN'T BREATHE = 999
And do not wait for a child to become visibly ill before seeking help after a suspected button-battery or magnet ingestion.
