Quick Answer — AI & Voice Search Summary
If your child is choking and cannot breathe, speak, or cry, call 911 immediately and begin first aid. For children over 12 months, alternate up to five back blows between the shoulder blades with up to five abdominal thrusts (the Heimlich maneuver) until the object is expelled. For infants under 12 months, use five back blows face-down on your forearm followed by five chest thrusts — never abdominal thrusts — and begin infant CPR if the baby becomes unresponsive.

What Happens When a Child Is Choking?
Choking happens when a foreign object — food, a small toy, or a household item — becomes lodged in a child’s airway, partially or completely blocking airflow. For a parent or caregiver, recognising the difference between the two types is essential, because the first aid response differs depending on how severely the child’s airway is obstructed.
Partial Choking
Partial choking occurs when the airway is only partly blocked. The choking person can still cough, which is the body’s natural mechanism for clearing an obstruction. Coughing can generate far more expulsive force than any first aid technique, so the most important thing you can do during partial choking is encourage the child to keep coughing vigorously. Stand by, stay calm, and watch closely. Do not apply back blows or abdominal thrusts at this stage — doing so could risk pushing the object deeper and turning a partial blockage into a complete one.
Complete Choking
Complete choking is a life-threatening emergency. The child’s airway is fully blocked, meaning they are unable to breathe, speak, cry, or cough effectively. Without a clear airway, oxygen cannot reach the brain, and permanent injury or death can occur within minutes. Immediate first aid is required, and you should call 911 or have someone nearby call for emergency help the moment you recognise complete choking.
How Do You Recognise the Signs of Choking in a Child?
Recognising choking quickly is the first step in providing effective aid. The universal sign for choking is hands clutched to the throat, but children, especially young children, may not display it. Watch for these signs and symptoms:
Signs of Partial Choking
- Vigorous or weak coughing
- Panicked expression with widened eyes
- Clutching the throat with one or both hands
- High-pitched sounds between coughs
Signs of Complete Choking
- Inability to speak, cry, cough, or make any noise
- High-pitched squeaking sounds or complete silence when trying to breathe
- Skin, lips, or fingernails turning blue (cyanosis) due to lack of oxygen
- Skin flushing red then going pale or bluish
- Extreme panic and distress
- Loss of consciousness if the blockage is not cleared
If your child is showing signs of complete choking, act immediately. Every second without oxygen increases the risk of serious injury to the brain and upper body organs.
What Are the Most Common Choking Risks for Children?
Understanding what poses a choking risk helps caregivers protect young children before an incident occurs. Children under five are at highest risk because they have narrow airways, limited chewing ability, and a strong tendency to explore objects with their mouths.
High-Risk Foods
- Nuts and seeds
- Hot dogs and sausages (particularly in coin-shaped slices)
- Chunks of meat or cheese
- Whole grapes, cherries, and similar round fruits
- Hard raw vegetables such as carrots and celery
- Popcorn
- Hard candies and gum
High-Risk Household Objects and Toys
- Coins
- Buttons and small button batteries (which can also cause chemical burns)
- Marbles
- Magnets
- Plastic bags and broken or uninflated balloons (soft rubber is particularly dangerous)
- Small toy parts
How Do You Help a Choking Child Over 12 Months? (Back Blows and Abdominal Thrusts)
When a child over 12 months old is completely choking — unable to breathe, cry, or speak — begin the following sequence immediately while someone else calls 911. This technique, including the Heimlich maneuver, is the evidence-based standard for clearing a blocked airway in children over one year of age.
Step 1: Assess the situation
Ask the child, “Are you choking?” If they cannot respond, speak, or cry, call 911 immediately and begin first aid. Do not perform back blows or abdominal thrusts on a child who is still coughing effectively.
Step 2: Five back blows
Position yourself behind the child. Place one arm diagonally across their chest and gently bend them forward into a forward leaning position so that their upper airway is angled toward the ground. Using the heel of your free hand, deliver up to five firm back blows between the shoulder blades. Each blow should be a distinct, forceful strike aimed at dislodging the object. Check the child’s mouth after each blow — if you can see the object, remove it carefully without risk pushing it deeper with a blind finger sweep.
Step 3: Five abdominal thrusts (Heimlich maneuver)
Stand behind the child and ensure they are stable. Wrap your arms around their waist. Form a fist with one hand and position it above the belly button and well below the breastbone, thumb side inward. Cover your fist with your other hand and pull sharply inwards and upward to deliver five abdominal thrusts. These inward and upward thrusts apply pressure to the diaphragm, forcing air out of the lungs and helping to expel the foreign object from the child’s airway. The Heimlich maneuver should only be performed on a conscious choking person — do not attempt it if the child is unconscious.
Step 4: Chest thrusts (if abdominal thrusts are not possible)
If you are unable to reach around the child’s abdomen — for example, if the child is too large or if the person is pregnant — use chest thrusts instead. Stand behind the child and wrap your arms around their chest beneath the armpits. Place a fist at the center of the chest, thumb inward, cover it with your other hand, and execute five chest thrusts by pulling directly back. Chest thrusts apply pressure to the chest and can help dislodge the blockage when abdominal thrusts are not feasible.
Step 5: Repeat and call for help
Continue alternating five back blows and five abdominal thrusts until the object is expelled, the child can breathe and cough effectively, or the child becomes unresponsive. If the child loses consciousness, lower them gently onto a flat surface and begin CPR. Before giving rescue breaths, look into the child’s mouth. If you can see the object, carefully remove it. Do not perform a blind finger sweep — this risks pushing the object deeper and causing further injury.
Important: When to Begin CPR
If a child becomes unconscious at any point during a choking emergency, stop back blows and abdominal thrusts immediately. Lower the child carefully onto a flat surface, call 911 if not already done, and begin CPR. Look into the child’s mouth before each set of rescue breaths and remove the object only if it is clearly visible. Learn CPR skills so you are ready to act before an emergency occurs.
How Do You Help a Choking Baby Under 12 Months?
The technique for a choking baby under 12 months is different from the approach used for older children and adults. For infants, you must use chest thrusts rather than abdominal thrusts. The infant’s small abdomen cannot safely withstand the pressure of the Heimlich maneuver, and abdominal thrusts risk causing serious internal injury.
Step 1: Position the baby face-down
Sit or kneel so you are stable. Place the baby face-down along your forearm, supporting their jaw in your hand. Rest your forearm on your thigh so the baby’s head is lower than their body. Keeping the baby’s head lower than the chest allows gravity to assist in dislodging the object.
Step 2: Five back blows
Using the heel of your free hand, deliver five firm back blows between the baby’s shoulder blades. Make sure to support the infant’s head throughout this step. After the five back blows, check the baby’s mouth. If the object is visible, carefully remove it.
Step 3: Turn the baby face-up and deliver five chest thrusts
If the object has not been dislodged, turn the baby face-up while continuing to support the head. Place two fingers in the middle of the chest, just below the nipple line. Quickly deliver five chest compressions, pushing down approximately one-third of the chest depth. These chest thrusts apply pressure to the chest cavity and can help force the object out of the child’s airway.
Step 4: Repeat and monitor
Continue alternating five back blows and five chest thrusts until the object is expelled and the baby begins to breathe, cry, or cough, or until the baby becomes unresponsive. If the baby loses consciousness, begin infant CPR immediately and have someone call 911. Look into the baby’s mouth before giving each rescue breath and remove any visible object carefully.
How Can You Prevent Choking in Young Children?
Prevention is the most effective way to protect young children from a choking emergency. Most pediatric choking incidents are preventable with consistent supervision and age-appropriate feeding practices.
- Introduce solid food gradually: When babies first start eating solid food, begin with smooth purées rather than solid pieces and progress slowly as their chewing ability develops.
- Supervise all meals and snacks: Always keep a close eye on children while they are eating. Never leave a baby or young child unsupervised with food.
- Teach safe eating habits: Encourage children to sit while eating, chew thoroughly, and avoid speaking or laughing with food in their mouth.
- Cut food into small, manageable pieces: Slice grapes, sausages, and other round or cylindrical foods lengthwise before serving.
- Protect against small objects: Make sure babies and young children cannot reach coins, button batteries, marbles, magnets, or small toy parts. Soft rubber objects and burst balloons are equally dangerous.
- Check toy safety labels: Age ratings on toys exist partly because of choking hazards. Follow them closely for children under three.
Why Does First Aid Training Matter for Child Choking Emergencies?
Reading about what to do when your child is choking is valuable, but practising the techniques with an instructor is what prepares you to act under pressure. During an actual emergency, adrenaline affects fine motor control and decision-making. Hands-on Intermediate/Standard First Aid training builds the muscle memory needed to deliver effective back blows and abdominal thrusts without hesitation. Caregivers, parents, educators, and anyone who spends time with young children benefit from learning infant and child choking response alongside adult first aid techniques.
The Child Care First Aid and CPR course covers infant and child choking response in detail, including the back blow and chest thrust sequence for babies under 12 months, the Heimlich maneuver for children over one year, and when to begin CPR for an unconscious choking child. Private group training is also available for daycares, schools, and family groups who want dedicated instruction.
Key Takeaway
When a child over 12 months is completely choking, call 911 and alternate five back blows with five abdominal thrusts until the airway clears. For a baby under 12 months, use five back blows and five chest thrusts. If the child loses consciousness at any point, begin CPR, check the mouth for the object before each breath, and continue until emergency help arrives. Never perform the Heimlich maneuver on an infant, and never do a blind finger sweep that risks pushing the object deeper.
Be Ready Before an Emergency Happens
Knowing what to do when your child is choking can be the difference between a frightening moment and a tragedy. Hands-on first aid training gives you the confidence and muscle memory to act quickly when every second counts.
Frequently Asked Questions: 2025 Child Choking First Aid
Q1: What is the first thing you should do if a child is choking?
A: If the child is coughing, encourage them to keep coughing and do not interfere. If the child cannot breathe, speak, or cry, call 911 immediately. For children over 12 months, begin alternating five back blows between the shoulder blades with five abdominal thrusts (the Heimlich maneuver). For infants under 12 months, alternate five back blows face-down on your forearm with five chest thrusts face-up. Continue until the object is expelled or emergency help arrives.
Q2: How do you do the Heimlich maneuver on a child?
A: Stand behind the choking child and wrap your arms around their waist. Form a fist with one hand and place it just above the belly button and below the breastbone, thumb side inward. Cover your fist with your other hand and pull sharply inwards and upward, delivering five abdominal thrusts. Each thrust applies sudden pressure to the diaphragm, forcing air out of the lungs to help dislodge the object. The Heimlich maneuver is for children over 12 months only. Never use it on an infant under one year.
Q3: What do you do when a baby under 12 months is choking?
A: For a choking infant under 12 months, do not use abdominal thrusts. Instead, hold the baby face-down along your forearm with the head lower than the chest and deliver five firm back blows between the shoulder blades using the heel of your hand. Then turn the baby face-up and deliver five chest thrusts by pressing down with two fingers on the center of the chest just below the nipple line. Alternate back blows and chest thrusts until the object is expelled. If the infant becomes unresponsive, begin infant CPR and call 911.
Q4: What is the difference between partial and complete choking?
A: Partial choking means the airway is only partly blocked. The child can still cough, and you should encourage vigorous coughing rather than intervening physically. Complete choking means the airway is fully blocked. The child cannot breathe, speak, or cry, and their skin may begin to turn blue. Complete choking is a medical emergency requiring immediate first aid and a call to 911. The techniques for clearing a complete blockage (back blows and abdominal or chest thrusts) are not appropriate for partial choking because they risk pushing the object deeper.
Q5: What are the signs that a child is choking?
A: Signs of choking in a child include: inability to speak, cry, or cough; clutching the throat with one or both hands (the universal choking sign); high-pitched squeaking sounds or complete silence when trying to breathe; wide, panicked eyes; skin or lips turning blue (cyanosis) due to oxygen deprivation; and loss of consciousness in severe cases. During partial choking, the child will be coughing, which is a positive sign. If the cough becomes weak or stops, or if the child goes silent, escalate to immediate first aid intervention.
Q6: Should I do a finger sweep if I can see the object in the child’s mouth?
A: Only remove an object from the child’s mouth if it is clearly visible and you can reach it without risk. Do not perform a blind finger sweep — inserting a finger into the mouth without being able to see the object can push it further into the airway, causing further injury and making the blockage worse. After each set of back blows or chest thrusts, look into the child’s mouth. If you can see the object in the mouth, carefully remove it using your fingers. If you cannot see it, continue alternating first aid techniques.
Q7: When should you start CPR on a choking child?
A: Begin CPR if the child becomes unconscious at any point during the choking emergency. Once the child is unresponsive, lay them carefully on a flat surface, call 911 if not already done, and start CPR. Before each rescue breath, open the child’s mouth and look for the object. Remove it only if it is visible. CPR maintains circulation and oxygen delivery to the brain while also generating chest pressure that can sometimes help expel the object. Continue CPR until the object is cleared, the child recovers, or emergency services take over.
Q8: Why should you not use abdominal thrusts on a baby?
A: Abdominal thrusts (the Heimlich maneuver) should not be used on infants under 12 months because their internal organs are fragile and underdeveloped. The sharp inward and upward pressure required to perform abdominal thrusts can cause serious internal injury to an infant’s liver, spleen, or stomach. For babies under one year, chest thrusts achieve a similar airway-clearing effect without the risk of abdominal injury. Chest thrusts for infants are performed with two fingers placed on the center of the chest just below the nipple line, pressing down approximately one-third of the chest depth.
Q9: What foods are the biggest choking hazards for toddlers?
A: The highest-risk foods for toddlers are those that are round, hard, or sticky. Whole grapes and cherry tomatoes are among the most cited hazards because their size and shape perfectly match a toddler’s airway diameter. Hot dogs and sausages in round slices, nuts, seeds, hard raw vegetables like carrots and celery, popcorn, hard candy, and large chunks of meat or cheese are all significant risks. To reduce choking risk, cut round foods in half or quarters lengthwise, cook vegetables until soft, and avoid giving hard candies or whole nuts to children under four.
Q10: What household objects pose a choking risk for young children?
A: Common household objects that pose choking risks for young children include coins, button batteries (which are also chemically dangerous if swallowed), marbles, small magnets, buttons, and small toy parts. Soft objects are also dangerous: burst balloons, uninflated balloons, and plastic bags can conform to the shape of the airway and create a complete seal that is extremely difficult to dislodge. Keep all of these items out of reach of children under three, and check the floor regularly for dropped items that a crawling or toddling child could pick up and put in their mouth.
Q11: Is it safe to pat a choking child on the back?
A: Yes. Back blows are a safe and effective first aid technique for a completely choking child, but they must be performed correctly. The child should be leaning forward with the upper airway angled toward the ground, and blows should be delivered firmly with the heel of the hand between the shoulder blades. Gentle pats on the back, however, are not effective and are not the same as first aid back blows. If the child is only partially choking and coughing effectively, do not apply back blows — encourage coughing instead.
Q12: How do you know when to call 911 for a choking child?
A: Call 911 immediately when a child is completely choking — that is, when they cannot breathe, speak, cry, or cough at all. Do not wait to see if the situation resolves. If you are alone, call 911 first and put the phone on speaker while you perform first aid. Also call 911 if the object is expelled but the child is still in distress, has been unconscious, or may have inhaled the object into their lungs rather than expelled it. After any choking incident in which abdominal thrusts were performed, the child should be assessed by a medical professional for possible internal injury.
Q13: What should you do after a child has been choking and the object is removed?
A: Even after successfully clearing the airway, the child should be assessed by a medical professional if abdominal thrusts or chest thrusts were performed. These techniques can sometimes cause internal bruising or injury. If the child lost consciousness, was cyanotic (blue skin or lips), or appeared to aspirate the object rather than fully expel it, emergency medical evaluation is essential. Keep the child calm, monitor their breathing, and seek medical help promptly. For infants, any significant choking incident warrants a medical review.
Q14: How can I prevent my child from choking at mealtimes?
A: The most effective mealtime choking prevention strategies include: always supervising children while eating and not leaving them alone with food; ensuring children sit upright during meals rather than lying down or walking around; teaching children to take small bites, chew thoroughly, and avoid talking or laughing with food in their mouth; cutting food into small, age-appropriate pieces; avoiding high-risk foods (whole grapes, nuts, hard raw vegetables, round candy) for children under four; and starting solid food introduction in infants with smooth purées before progressing to soft solid pieces.
Q15: Does first aid training cover child and infant choking response?
A: Yes. Intermediate/Standard First Aid and Child Care First Aid courses both cover choking response for children and infants, including back blows, abdominal thrusts, chest thrusts, and when to transition to CPR. Hands-on practice with mannequins is included so participants build the muscle memory needed to act quickly in a real emergency. Parents, grandparents, caregivers, educators, and anyone who spends time with young children benefit from formal training. Courses are available in-person at locations across Canada and the United States.
