Choking is every parent’s worst nightmare. It happens in a heartbeat—a stray grape, a small toy, or a piece of hard sweets can transform a quiet afternoon into a life-threatening emergency. Knowing the correct Child Choking First Aid procedures isn’t just a “good-to-have” skill; it is a vital necessity for anyone responsible for the safety of young children.
As London’s leading provider of paediatric first aid training at Practical First Aid, we see firsthand how confidence saves lives. This comprehensive guide outlines the critical steps to take when a child is choking, the physiological differences between infants and older children, and the essential aftercare required.
Understanding the Mechanics of Choking
Before diving into the “how-to,” it is important to understand what is happening inside the body. Choking occurs when a foreign object lodges in the pharynx or trachea, causing a partial or complete airway obstruction.
-
Partial Obstruction: The child can still breathe, cry, or cough. They may be distressed, but are still getting some oxygen.
-
Complete Obstruction: The child cannot breathe, cough, or make any sound. Their face may turn red or blue (cyanosis), and they will eventually lose consciousness.
What is the First Aid for Choking Children?
The primary objective of Child Choking First Aid is to use physical force to increase pressure in the chest and abdomen to “pop” the object out of the airway, much like a cork from a bottle.
Step 1: Assess the Severity
If the child is coughing loudly, encourage them to keep coughing. A strong cough is the most effective way to clear an obstruction. Do not interfere if they are coughing effectively, as you might push the object deeper.
Step 2: The “5 and 5” Approach
If the cough is silent or ineffective, you must intervene immediately using a combination of back blows and abdominal thrusts (for children over one year old).
What are the 6 Action Steps for a Choking Child?
For children over the age of one, the British Red Cross and Resuscitation Council UK recommend a specific sequence of actions.
1. Identify the Obstruction
Check if the child can breathe or speak. If they are clutching their throat (the universal sign for choking) and cannot make sound, proceed to step two.
2. Deliver 5 Back Blows
Lean the child forward. Support their chest with one hand. Use the heel of your other hand to deliver five firm blows between the shoulder blades. The goal is to create a vibration and pressure change that dislodges the object.
3. Deliver 5 Abdominal Thrusts (The Heimlich Manoeuvre)
If back blows fail, stand behind the child. Wrap your arms around their waist. Make a fist and place it just above their belly button (but below the ribs). Grasp your fist with your other hand and pull sharply inwards and upwards.
4. Repeat the Cycle
Continue the cycle of 5 back blows and 5 abdominal thrusts until the object is expelled or the child becomes unresponsive.
5. Call 999 or 112
If the object does not come out after the first cycle, someone should call the emergency services immediately. If you are alone, perform one minute of first aid before stopping to call.
6. Start CPR if Unconscious
If the child loses consciousness, lay them gently on a flat, firm surface. Open the airway and begin Cardiopulmonary Resuscitation (CPR). Start with 5 initial rescue breaths, followed by 30 chest compressions and 2 breaths.
What are the 5 Steps When Helping a Choking Infant?
Infants (under 12 months) require a different approach because their organs are fragile and their anatomy is smaller. Never perform abdominal thrusts on a baby.
1. Position the Infant
Lay the baby face down along your thigh or forearm, supporting their head with your hand. Keep their head lower than their chest so gravity can assist.
2. 5 Back Blows
Deliver five firm back blows between the shoulder blades using the heel of your hand.
3. Flip and Check
Turn the baby over so they are face up on your other thigh. Look in the mouth. If you see the object, remove it carefully. Do not perform a blind finger sweep, as this can push the object further down.
4. 5 Chest Thrusts
If the airway is still blocked, use two fingers in the centre of the baby’s chest (just below the nipple line). Deliver five sharp downward thrusts, similar to CPR compressions but slower and more deliberate.
5. Repeat and Call for Help
Cycle through 5 back blows and 5 chest thrusts. Call 999 immediately if the first cycle fails to clear the airway.
Does a Child Need to See a Doctor After Choking?
Yes. This is a critical point that many parents overlook. Even if the child seems perfectly fine after the object is expelled, medical evaluation is mandatory for the following reasons:
-
Residual Particles: If the child was choking on food (like a nut), small fragments may have been inhaled into the lungs (aspiration). This can lead to pneumonia or an abscess days later.
-
Internal Damage: Abdominal thrusts and chest thrusts are forceful manoeuvres. They can cause internal bruising or damage to organs like the spleen or liver.
-
Airway Irritation: The object may have scratched the throat or caused swelling, which could lead to breathing difficulties later in the evening.
Always take your child to an Urgent Care Centre or A&E following a significant choking episode.
Common Choking Hazards: Prevention is Better Than Cure
While knowing Child Choking First Aid is essential, preventing the incident is the gold standard of child safety.
High-Risk Foods
-
Whole Grapes: These are the perfect size to plug a child’s airway. Always slice them lengthways.
-
Cherry Tomatoes: Like grapes, these should be quartered.
-
Hot Dogs/Sausages: Never cut them into round “coins.” Slice them into thin strips.
-
Hard Sweets and Marshmallows: These do not dissolve quickly and can get stuck easily.
-
Popcorn and Nuts: Generally not recommended for children under the age of five.
Household Objects
-
Button Batteries: These are a double threat—they are a choking hazard and can cause fatal chemical burns within hours.
-
Coins: The most common non-food item swallowed by children.
-
Balloons: A popped balloon can be inhaled and form an airtight seal over the trachea.
-
Small Toy Parts: Always check the age rating on toys (the 0-3 warning symbol).
The Importance of Paediatric First Aid Training
Reading an article is a great first step, but it cannot replace hands-on practice. In a high-stress situation, “muscle memory” takes over. When you attend a Practical First Aid course in London, you get the opportunity to:
-
Practice on Mannequins: Feel exactly how much pressure is needed for a back blow or a chest thrust.
-
Ask Experts: Our instructors are seasoned professionals who can clarify the nuances between infant and child techniques.
-
Gain Certification: Many childcare professionals and New Parents find that having a formal qualification provides immense peace of mind.

FAQs About Child Choking First Aid
What should I do if my child is choking and I am alone?
If you are alone, perform one full minute of first aid (back blows and thrusts) before stopping to call 999. If you have a mobile phone, put it on speakerphone while you continue the life-saving manoeuvres.
Can I use the “LifeVac” or anti-choking devices?
While some suction devices are on the market, the Resuscitation Council UK and the NHS still prioritise manual manoeuvres (back blows and thrusts) as the primary treatment. These manual methods are proven, require no equipment, and can be started instantly.
How do I know if it’s a partial or full blockage?
In a partial blockage, the child will be distressed and likely make a “wheezing” or “crowing” sound. In a full blockage, there is “silent” struggling. If they can’t make any sound, you must act immediately.
The Bottom Line
Mastering Child Choking First Aid is one of the most empowering things a parent or carer can do. By following the 6 action steps—alternating between back blows and abdominal thrusts—you provide the best possible chance for a positive outcome.
However, remember that the “after-effects” of choking can be just as dangerous as the event itself. Always seek medical professional advice if your child has suffered an airway obstruction.
