Choking baby (under one year old)

Dr Lynn Thomas, OStJ, BSc, MB.BS, MA, FRCPClinically reviewed: 05/10/2026

As you start weaning your baby, and they become more active, they may be at risk of choking.

What is choking?

When a baby is choking, their airway is partly or completely blocked meaning that they may be unable to breathe properly. As you start weaning your baby and they begin eating solid foods or playing with small objects, they may be at risk of choking.

Signs and symptoms

A choking baby may:

  • be unable to breathe, cry, or cough

  • show signs of distress.

If your baby is under one year old, this advice will help you to know what to do if they choke.

What to do when a baby is choking

  1. 1

    If you think a baby is choking, then they need your help straight away. If they can breathe, are making noises, or coughing, then they may be able to clear their own airway.

    If a baby cannot breathe, cry, or cough, they may be choking and you will need to give five back blows.

    • Lay the baby face down along your thigh and support their head

    • Give up to five back blows between the shoulder blades

  2. 2

    If back blows fail to clear the obstruction, give up to five chest thrusts.

    • Turn the infant onto their back and lay them on your knees or on a firm surface

    Place both thumbs on the breastbone one finger’s breadth below the nipple line, with the fingers encircling the baby's chest, and push sharply with a downwards motion. Repeat up to five times.

  3. 3

    Call 999 or 112 for emergency help if the obstruction hasn't cleared.

    Take the baby with you to make the call.

    Keep repeating up to five back blows and up to five chest thrusts until help arrives, or the obstruction is cleared (e.g. the baby starts coughing, loud breathing or crying), or the baby becomes unresponsive. If the baby becomes unresponsive , carry out a Primary Survey (DRABC) assessment and start baby CPR if required.

    All babies who have received chest thrusts should be seen in hospital.
