The short answer
Gagging usually allows a baby to make sounds, cough and breathe. Serious choking may stop effective coughing, crying or breathing. If your baby cannot breathe or cough effectively, call 999 and start infant first aid.

Keep in mind
- Gagging is usually noisy and a baby may still cough and breathe effectively.
- Silence, ineffective coughing or inability to breathe suggests a serious obstruction.
- For babies under one, give back blows and chest thrusts; do not use abdominal thrusts.
- Upright feeding, safe textures and close supervision reduce choking risks.
What might gagging look like?
When you offer a lumpier food for the first time, your baby might pull a face, push their tongue forwards or make a retching sound. Gagging is a protective reflex which helps move food away from the back of the mouth. It can be startling even when your baby is breathing.
A baby who is gagging may cough, make a noise, go red in the face or push the food out. These signs do not on their own mean the airway is blocked. Do not rely only on facial colour: watch their breathing and whether they can cough effectively.
What signs suggest choking?
If food badly blocks the airway, your baby may be unable to cough strongly, cry or make a sound. Struggling to breathe in silence or turning blue is a medical emergency.
An obstructed airway can sometimes let a little air through. A faint sound does not mean that your baby is safe. An ineffective cough or suspected difficulty getting air in should be treated as urgent.
How should you respond to gagging?
If your baby is coughing effectively, crying or breathing, stay close, let them cough and watch carefully. Never put your fingers blindly into their mouth as this could push the food further back.
Do not give back blows or try to pull food out while your baby is coughing effectively. If breathing or sound stops suddenly, or the cough becomes ineffective, move straight to choking first aid.
What should you do if a baby under one is choking?
If your baby cannot breathe, cry or cough effectively, shout for help and ask someone to call 999. If you are alone, get emergency help as soon as possible while continuing first aid.
Support your baby’s head and neck and lay them face down along your forearm or thigh with their head lower than their body. Give up to five sharp back blows between the shoulder blades with the heel of your hand; check whether the object has come out.
If the blockage remains, turn your baby face up, keeping their head lower than their body. Use the two-thumb encircling technique for up to five sharp chest thrusts, supporting the back with your fingers. Repeat the sequence of back blows and chest thrusts if needed.
Never give abdominal thrusts to a baby under one. Do not sweep their mouth with a finger unless an object is clearly visible and easy to remove.
What if your baby becomes unresponsive?
If your baby becomes unresponsive, put them on a firm, flat surface and make sure 999 has been called. If they are not breathing normally, follow the call handler’s instructions. Paediatric basic life support starts with five initial rescue breaths, then CPR according to your training. Remove an object only if it is clearly visible; do not blindly sweep the mouth.
Written guidance cannot replace practical first aid training. Learning infant choking first aid and resuscitation before an emergency can make a real difference.
Is gagging common when starting solids?
When first eating solid foods, babies are learning how to move food around their mouths. Some textures may trigger more gagging; one episode does not mean that the food should never be offered again.
The aim is to offer a texture your baby can manage and to recognise the difference between gagging and airway obstruction. Frequent distressing gagging, coughing with swallowing or difficulty eating deserves professional advice.
What can you try today?
Before offering food, make sure your baby is sitting upright with good support for their head and trunk. Stay alongside them for the whole meal; never feed them when lying down, moving around or travelling in a car.
Avoid hard raw foods, whole grapes, whole nuts, and large round or sticky pieces. Prepare foods in suitable shapes and textures, and consider taking an infant first aid course.
When should you seek medical help?
Call 999 for an ineffective cough, inability to breathe or cry, blue discolouration or unresponsiveness. Even when the object has come out after choking first aid, seek medical assessment.
If your baby regularly coughs during meals, finds swallowing difficult, refuses feeds or has growth concerns, speak to your GP or health visitor. The cause cannot be established from a written description alone.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- Call 999 if your baby cannot cough effectively, cry or breathe.
- Blue lips, severe breathing problems or unresponsiveness require emergency assistance.
- Get medical advice after choking first aid even if the obstruction clears.
- Repeated coughing or difficulty swallowing at meals needs GP assessment.
