Gagging is loud, red-faced and alarming, and it is the airway working exactly as designed. Choking is quiet. Almost every parent has these the wrong way round, and it changes what you should do.
Reading is not the same as having done it with your hands. A two-hour paediatric first aid course will teach you more than any article can, and you will not forget it under pressure the way you will forget this. Book one — St John Ambulance and the British Red Cross both run them, and some are free.
The technique below is described because a parent at two in the morning with no course booked still needs something. It is a floor, not a substitute.
This is the single most useful thing on this page, and it is why so many parents retreat to smooth purée long after their baby was ready for texture.
The gag reflex in a baby sits much further forward on the tongue than in an adult. It is triggered easily and often, and its entire purpose is to push food back out before it can reach the airway. It is a protective mechanism doing its job. It looks and sounds horrifying.
What to do: Stay calm, stay close, let them work it out. Do not put your fingers in their mouth. Do not pick them up and turn them over. Interfering can turn a gag into a choke.
What to do: Act immediately. The steps are below. Shout for someone to call 999 while you start.
Noise is good. Silence is the emergency. A child who is coughing loudly is shifting air past the obstruction, and their own cough is more effective than anything you can do. Let them cough. A child who has gone quiet, or who is making a thin whistling sound and cannot cry, needs help this second.
Shout for help. If someone else is there, send them to call 999 immediately while you begin. If you are alone, start the steps — you can call after the first cycle, or put the phone on speaker.
Head lower than their bottom. Support their jaw and head with your hand, keeping your fingers clear of their throat. Sitting down and laying them along your thigh gives you far better control than standing.
With the heel of your hand, strike firmly between the shoulder blades. Up to five times. Firmly — this is not a pat. Check after each one to see whether the obstruction has come out. Stop as soon as it has.
Lay them face up along your thighs, feet towards you, head lower than their chest. Place two fingers in the middle of the breastbone, just below the nipple line. Push sharply inwards and upwards, up to five times. These are sharper and slower than chest compressions.
Alternate five back blows and five chest thrusts. Keep going. If they become unresponsive at any point, begin infant CPR and make sure an ambulance is on its way.
No abdominal thrusts. The Heimlich manoeuvre is not used on babies under one year old — their liver and other organs sit low and unprotected, and abdominal thrusts can cause serious internal injury.
No blind finger sweeps. Never put a finger into the mouth to hook something out unless you can clearly see it and can get it in one movement. Sweeping blindly pushes the obstruction further down.
Do not hold them upside down by the ankles. It does not work and it is dangerous.
The sequence changes. Over one year old, abdominal thrusts are used.
If they are coughing effectively, that is the best thing happening. Do not interrupt it. Stay with them.
Lean them forwards, supporting their chest with one hand so the obstruction comes out of the mouth rather than travelling further down. Five firm blows between the shoulder blades with the heel of your hand.
Stand or kneel behind them. Put your arms around their waist and make a fist just above the belly button. Grasp it with your other hand and pull sharply inwards and upwards. Up to five times.
Alternate five and five. Anyone who has received abdominal thrusts must be checked by a doctor afterwards, even if they seem completely fine — there is a real risk of internal injury.
Most choking incidents involve the same short list of foods, and nearly all of them can be made safe by cutting them differently.
| Food | Why it is a risk | Make it safe |
|---|---|---|
| Grapes, cherry tomatoes, olives, large berries | Round, firm, and exactly the diameter of a small airway. The commonest serious hazard. | Quarter lengthways, not across. Until at least five years old. |
| Whole nuts | Hard, irregular, and cannot be chewed by a child without a full set of molars. | Never whole before five. Smooth nut butter thinly spread, or finely ground. |
| Raw carrot, apple, hard vegetables | Snap into hard chunks that cannot be gummed down. | Cook until soft, or grate raw. |
| Sausages, hot dogs | Cylindrical — a slice is a perfect airway plug. | Quarter lengthways, then chop. |
| Popcorn, marshmallows, boiled sweets, jelly cubes | Inhaled easily, or expand and mould to the airway. | Avoid entirely under four. |
| Bread, especially fresh white | Compresses into a dense sticky ball. | Toast it. Toasted bread breaks up instead of balling. |
| Fish with bones | Fine bones are almost impossible to see. | Check with fingertips twice — before and after cooking. |
| Spoonfuls of thick nut butter | Sticks to the roof of the mouth and the back of the throat. | Spread thinly, or thin it with water, milk or yoghurt. |
Not to answer the door, not to fetch a cloth, not for thirty seconds. Choking makes no sound. There will be nothing to hear.
Never reclined, never in a car seat, never lying down, never propped. A baby must be upright and supported, ideally with their feet resting on something. Feet dangling in mid-air makes a baby less stable, and less stable means less able to deal with food in their mouth.
You cannot see them, and you cannot reach them. Stop first.
An open mouth mid-breath and a piece of food are a bad combination. A tired baby has poorer coordination — and mealtimes that arrive after the tiredness has already set in go badly for several reasons.
Do not load the tray. A baby who can reach six pieces will put six pieces in.
It is worth saying plainly, because fear of choking pushes a lot of families into keeping their baby on smooth purée far longer than they should. Gagging is how a baby calibrates. It happens most between six and nine months and becomes markedly less frequent as they get the hang of it. Avoiding all texture to avoid all gagging delays the very skill that makes eating safe.
