Most parents know that whole grapes, popcorn, hard candy and small toys can be choking hazards.
But choking hazards are not limited to the items we usually see on warning lists.
A crayon can snap. A wheel can separate from a toy. A balloon can pop. A button can fall from clothing. A small game piece meant for an older sibling can quietly roll beneath the couch.
The item may not have looked dangerous when we first brought it home. The risk appeared when it broke, detached, deflated or ended up within reach of a child who still explores with their mouth.
Health Canada specifically identifies small or broken crayons, coins, pen caps, jewellery, hair clips, screws, buttons and keys as common choking hazards for children under three. Small toys, balls and loose or broken toy parts also need to be kept away from young children.
This does not mean we need to become afraid of everything in our homes.
It means we can learn how to look beyond the name of an item and consider its size, shape, condition and what could happen if it breaks.
One of the most helpful questions we can ask is:
What happens if this breaks?
That simple question can help us notice many of the unexpected choking hazards parents and caregivers often overlook.
What Makes an Everyday Item a Choking Hazard?
Health Canada explains that small objects present choking, ingestion and inhalation hazards to young children.
Any toy likely to be used by a child under three should be large enough that the toy itself, and any part that could reasonably detach from it, does not create a small-parts hazard. This includes eyes, wheels, decorations, puzzle pegs, batteries and other attachments.
When looking at an item, consider whether it:
Is already small enough to fit inside a young child’s mouth
Is round, smooth or shaped in a way that could block the airway
Can snap, crumble or break into smaller pieces
Has parts that could loosen or detach
Is made from brittle plastic that could break when dropped
Contains an accessible battery or magnet
Can become soft, flexible or compressed
Can expand after being swallowed
Belongs to an older child but may be accessible to a younger sibling
Is being used by a child who still frequently mouths non-food items
Age recommendations are important, but they are only one part of the picture.
A child’s developmental stage and behaviour matter too. Some children continue mouthing toys and household objects beyond age three. Small items should remain out of reach for as long as that behaviour continues.
Choking and Swallowing Hazards Are Not Always the Same
Choking happens when food or another object blocks the airway and prevents air from moving effectively.
An ingestion hazard causes injury after an item has been swallowed.
Some objects can be both.
Button batteries, small powerful magnets and water beads may be small enough to become choking hazards, but they can also cause serious internal injuries even when they pass through the airway and the child continues breathing.
That distinction matters.
A child who swallowed one of these objects may appear well at first. Breathing normally does not mean the risk has passed.
We will cover these higher-risk items in more detail below.
How to Use a Small-Parts Tester
A small-parts tester, sometimes called a choke tube, is based on the small-parts cylinder used in Canadian product testing.
The cylinder helps identify objects that have a size and shape that may create a choking or ingestion hazard for young children. If an item can be fully enclosed inside the tester, it should be kept away from children under three and older children who still mouth objects.
To use one:
Place the object or detached piece into the tester.
Do not force or compress it unless that is how the object would reasonably behave.
Check whether the entire item fits inside.
Repeat the test with any part that could detach or break away.
The tester is a helpful screening tool, but it cannot identify every hazard.
An item does not automatically become safe because it remains partly outside the cylinder. Long objects, flexible balloon pieces, accessible batteries, magnets and materials that swell after swallowing can still present serious risks.
The tester is one part of a broader safety check, not a guarantee.
Unexpected Choking Hazard #1: Crayons and Art Supplies
Crayons do not always look like choking hazards.
A full-sized crayon may appear too long to fit completely inside a child’s airway. However, regular crayons can snap into shorter pieces, and those broken pieces may be small enough to enter a young child’s mouth.
Health Canada includes small or broken crayons on its list of common household choking hazards for children under three.
Larger crayons, including jumbo, egg-shaped and palm-style crayons, may be easier for little hands to grasp and harder to place fully inside the mouth when they are intact.
However, no crayon is chew-proof or unbreakable.
For children who still mouth objects:
Choose art supplies labelled for their age group
Stay close and attentive while they use them
Remove crayons that have cracked or broken
Check the floor and seating area when the activity is finished
Store all art supplies out of sight and reach between activities
Pause the activity if the child repeatedly tries to chew or eat the materials
Try the activity again when the child is better able to use the product as intended
Other small art materials can also become choking hazards, including:
Marker caps
Pencil erasers
Chalk pieces
Beads
Googly eyes
Pom-poms
Sequins
Small stamps
Decorative gems
Pieces of modelling material that have hardened
A product labelled “non-toxic” has been assessed for toxicity. That label does not mean the item cannot become a choking hazard because of its size or shape.
Health Canada recommends choosing products labelled for children’s use, following the instructions on the label and remaining attentive while children use arts and crafts materials.
Unexpected Choking Hazard #2: Loose or Broken Toy Parts
A toy can be age-appropriate when it is intact and become hazardous after it is damaged.
Watch for:
Wheels separating from toy vehicles
Eyes, noses or decorations coming loose from stuffed toys
Squeakers coming out of bath toys
Puzzle pegs detaching
Brittle plastic cracking after a fall
Small accessories separating from dolls or action figures
Buttons, switches or decorative pieces becoming loose
Battery compartments that no longer close securely
Silicone or rubber pieces tearing after repeated chewing
Health Canada advises caregivers to repair or discard weak and broken toys and to check regularly for loose parts, broken pieces and sharp edges.
A quick toy inspection does not need to be complicated.
Every so often:
Gently pull on attached pieces
Look for cracks, splits or bite damage
Check seams and fasteners
Confirm that battery doors close securely
Remove toys with missing pieces
Check whether the product has been recalled
Follow the manufacturer’s cleaning and replacement instructions
This is especially important with second-hand toys because safety requirements may have changed and original instructions or warning labels may be missing.
Unexpected Choking Hazard #3: Toys Belonging to Older Siblings
The toy may not belong to the baby or toddler, but it can still end up in their hands.
Common examples include:
Small building bricks
Mini figures
Doll shoes and accessories
Marbles
Dice
Board-game pieces
Puzzle pieces
Toy jewellery
Craft beads
Small bouncy balls
Collectibles
Train-set accessories
Tiny pretend-food pieces
Parts from science or construction kits
This does not mean older children cannot enjoy toys designed for their age.
It means we may need a plan that allows them to play while keeping small pieces away from younger siblings.
Helpful strategies include:
Creating a designated small-parts play area
Using a table rather than the floor
Storing sets in containers with secure lids
Counting important pieces before and after play
Completing a floor check when playtime ends
Keeping older children’s toys in a room or area the younger child cannot access
Explaining why small pieces need to be put away without placing responsibility entirely on the older child
Water beads and magnetic toys intended for an older sibling require extra caution because they may cause serious internal injury if swallowed.
Unexpected Choking Hazard #4: Balloons and Broken Balloon Pieces
Balloons are soft, colourful and common at birthday parties, which can make them seem harmless.
However, uninflated balloons and pieces of broken balloons can be inhaled and block a child’s airway. Because balloon material is flexible, it may conform to the airway and be difficult to remove.
Health Canada recommends that balloons be used for decoration rather than play, that adults inflate them and that uninflated or broken balloon pieces always be kept away from children.
During parties and celebrations:
Keep unused balloons in a closed container
Have an adult inflate them
Do not allow children to chew or suck on balloons
Pick up every piece immediately if a balloon pops
Check beneath furniture and decorations
Dispose of deflated balloons rather than placing them in a toy bin
Ask guests and caregivers to help watch for pieces on the floor
Balloon safety matters beyond the toddler years. Health Canada notes that balloon pieces have caused choking deaths in children older than nine.
Unexpected Choking Hazard #5: Everyday Household Objects
Many choking hazards are not toys at all.
They are the objects we carry, use and set down throughout the day.
Examples include:
Coins
Buttons
Hair clips
Jewellery
Pen caps
Keys
Screws
Nuts and bolts
Bottle caps
Earbud tips
Removable zipper pulls
Small pieces of hardware
Loose craft supplies
Candy and gum
Decorative stones
Pieces from seasonal decorations
These items often appear in places children can reach:
On an entryway table
Inside an open purse
Beneath a couch
Beside a bed
On a bathroom counter
In a junk drawer
On the floor near a desk
Inside a visiting family member’s bag
In the cup holder or floor area of a vehicle
One of Health Canada’s recommendations is to scan the home from a child’s point of view by getting down to floor level and looking for hazards.
It is a simple strategy because adults and children see the same room very differently.
From the floor, we may notice the coin under the chair, the missing toy wheel beside the baseboard or the crayon piece that rolled beneath the cabinet.
Unexpected Choking Hazard #6: Button Batteries
Button batteries are found in many ordinary household products, including:
Remote controls
Key fobs
Watches
Hearing aids
Thermometers
Flameless candles
Toys
Bathroom and kitchen scales
Musical cards
Small lights and electronic decorations
A swallowed button battery can become lodged in the esophagus and cause severe internal burns in as little as two hours.
The battery does not need to leak to cause damage, and a child may not have immediate symptoms.
A suspected button battery ingestion is a medical emergency.
Go to the nearest emergency department immediately. Do not wait for symptoms to appear.
Our complete guide, Button Battery Safety: What Every Parent and Caregiver Should Know, explains where these batteries may be hiding, how to secure battery compartments and what to do if one may have been swallowed.
Health Canada also recommends keeping new and used batteries out of sight and reach, checking battery compartments regularly and choosing products with secure compartments whenever possible.
Unexpected Choking Hazard #7: Small Powerful Magnets
Small powerful magnets may be found in:
Building sets
Magnetic puzzles
Board games
Dolls and action figures
Alphabet magnets
Toy jewellery
Clothing accessories
Novelty desk toys
Adult magnet sets
Household products
Small magnets should never be placed in the mouth.
When more than one powerful magnet is swallowed, the magnets can attract each other through different sections of the digestive tract. This can cause blockages, twisting or tearing of the intestinal walls.
Symptoms may not appear immediately.
Health Canada advises seeking immediate medical attention whenever someone has swallowed, or may have swallowed, one or more magnets, even when they appear well.
Regularly inspect toys containing magnets and discard the product if a magnet is loose or if a magnetic piece is small enough to be swallowed.
Unexpected Choking Hazard #8: Water Beads
Water beads may also be called:
Sensory beads
Jelly beads
Hydro orbs
Crystal soil
Gel beads
Orb beads
They may be found in sensory activities, art kits, vase fillers, gardening products, foot baths and stress balls.
Dry water beads can be extremely small. After absorbing liquid, they can grow much larger.
If swallowed, a bead may continue expanding inside the body and cause a potentially life-threatening bowel obstruction. Beads can also roll away during play and remain hidden beneath furniture or in adjoining rooms.
Health Canada recommends that caregivers of children under five avoid keeping water beads in the home or classroom, even when they are intended for an older child or adult.
If a child may have swallowed a water bead, contact your provincial or territorial Telehealth service promptly for guidance. Seek emergency help for difficulty breathing, swallowing or other urgent symptoms.
Unexpected Choking Hazard #9: Worn Pacifiers, Teethers and Baby Products
Products designed for babies still need to be checked for wear.
Repeated sucking, chewing, cleaning and temperature changes can weaken materials over time.
Inspect pacifiers, teethers and other frequently mouthed products for:
Cracks
Tears
Holes
Swelling
Stickiness
Discolouration
Loose handles
Separating layers
Missing pieces
Bite damage
Changes in texture
Discard products that show signs of deterioration or no longer match the manufacturer’s instructions for safe use.
Do not attempt to permanently repair a damaged pacifier or teether with glue or tape. A repaired area may fail again or introduce another loose component.
Unexpected Choking Hazard #10: Food and Treats Found Outside Mealtimes
Food choking hazards are not only found on a high-chair tray.
A child may discover:
Hard candy that fell from a bag
Gum left on a table
Popcorn beneath a couch
Nuts from an older sibling’s snack
Whole grapes in an accessible lunch container
Dry pet food in a bowl
Food-shaped craft or sensory items
A food may be prepared appropriately during a supervised meal but become a different risk when a child finds it while crawling, walking or playing.
Keep young children seated upright and actively supervised whenever they eat. Avoid offering food while they are walking, playing, riding in a moving vehicle or sitting in a moving stroller.
For practical food-preparation guidance, read How to Safely Serve Grapes, Oranges, and Strawberries by Age and Stage.
A Five-Minute Choking Hazard Check
You do not need to search your entire home at once.
Choose one room and take five minutes.
Get Down to Your Child’s Level
Look beneath:
Furniture
Cabinets
Rugs
Play equipment
Beds
Tables
Car seats and vehicle seats
Check the Objects Within Reach
Ask:
Is this already small?
Could part of it come off?
Is it cracked, worn or damaged?
Does it contain a battery or magnet?
Could it roll into another room?
Does my child still put objects in their mouth?
What could happen if this breaks?
Check the Storage
Confirm that small objects are:
Out of sight and reach
Inside a secure container
Separated from toys intended for younger children
Counted and cleaned up after older-child activities
Stored safely at grandparents’ homes, childcare spaces and other places your child visits
Check for Recalls
Before using second-hand products or continuing to use an older toy, check Health Canada’s recalls and safety alerts database.
Remove recalled products and follow the instructions provided in the recall notice.
What Should You Do If a Child Is Choking?
Choking can be quiet.
If the child can cough strongly, breathe, cry or make sounds, encourage them to keep coughing and watch them closely.
Do not perform a blind finger sweep. Reaching into the mouth when you cannot clearly see and easily remove the object may push it farther back.
If the child cannot breathe, cough effectively, cry or make sounds:
Call 911
Begin the age-appropriate choking first aid you have been trained to perform
Follow the emergency dispatcher’s instructions
Begin CPR if the child becomes unresponsive
For a responsive infant younger than 12 months, review Infant Choking First Aid: The 5 + 5 Rule Explained.
A written article can help reinforce the steps, but it cannot replace practising CPR and choking first aid with a qualified instructor.

Preparation Is Not About Removing Every Risk
Children learn by exploring, creating and playing.
The goal is not to remove every activity or make our homes perfect.
It is to notice the risks that matter, make practical adjustments and update our spaces as children grow.
Sometimes that means choosing a larger crayon.
Sometimes it means throwing away a toy with a loose wheel.
Sometimes it means moving an older sibling’s building set to the kitchen table.
And sometimes it simply means stopping for a moment to ask:
What happens if this breaks?
That question helps us look beyond the label and recognize hazards before they become emergencies.
We cannot prevent every unexpected moment, but we can give ourselves the knowledge and skills to respond with greater confidence.
You’ve got this!
