First Aid for a Choking Infant (Under 1 Year Old)

Published: October 19, 2026Updated: October 19, 2026

Choking occurs when an infant's airway is partially or completely blocked by food, liquid, or a small foreign object. Recognizing the signs of severe obstruction and administering rapid back blows and chest thrusts can save an infant's life. This guide outlines the emergency steps recommended by pediatric emergency guidelines to clear an infant's airway safely.

Quick Summary

Alternate five firm back blows with five chest thrusts while keeping the infant's head lower than their chest until the obstruction clears or emergency help arrives.

Step-by-Step Guide

1

Assess the Severity of the Obstruction

Quickly observe whether the infant can cry, cough, or breathe. If the infant has a strong, forceful cough or is crying loudly, do not interfere, as coughing is the most effective way to clear the airway. If the infant cannot make sounds, has a silent or weak cough, struggles to breathe, or begins turning blue, intervene immediately for a severe airway obstruction.

Important: Never perform a blind finger sweep inside an infant's mouth, as this can push an unseen object deeper into the windpipe.

2

Call for Emergency Medical Services

Shout for someone nearby to call 911 (or your local emergency number) immediately and retrieve an automated external defibrillator (AED) if available. If you are entirely alone with the infant, begin the physical relief steps first and perform approximately two minutes of care before pausing briefly to call emergency services yourself.

3

Position the Infant Face Down

Lay the infant face down along your forearm, resting your arm on your thigh or lap for stability. Support the infant's head and lower jaw with your hand, ensuring you do not compress the soft tissues under the chin or twist the neck. Ensure the infant's head is angled downwards, positioned lower than their chest, allowing gravity to assist in dislodging the object.

4

Deliver 5 Firm Back Blows

Using the heel of your free hand, deliver up to five distinct, firm back blows between the infant's shoulder blades. Each blow should be delivered with enough force to attempt to dislodge the foreign object. Pause briefly after each blow to see if the blockage has cleared.

5

Turn the Infant and Deliver 5 Chest Thrusts

If the object does not dislodge, sandwich the infant safely between your forearms and turn them face up, keeping the head lower than the torso. Place two fingers or your thumbs in the center of the chest on the breastbone, just below the imaginary line connecting the nipples. Deliver up to five quick, downward chest thrusts, compressing the chest about 1.5 inches deep (approximately one-third the depth of the chest).

Important: Do not perform abdominal thrusts (the Heimlich maneuver) on an infant under one year old, as this can cause severe damage to the liver and other abdominal organs.

6

Repeat the Cycle Until Clear

Continue alternating between five back blows and five chest thrusts without interruption. Stop only if the object is successfully expelled, the infant begins crying or breathing normally on their own, or the infant becomes unresponsive. If the dislodged object becomes clearly visible and loose in the mouth, you may carefully sweep it out using a pinky finger.

7

Transition to Infant CPR if Unresponsive

If the infant becomes limp or unresponsive, gently place them onto a firm, flat surface and immediately begin infant CPR. Perform 30 rapid chest compressions, then open the airway and look inside the mouth; only remove an object if it is clearly visible. Provide two gentle rescue breaths covering both the infant's nose and mouth with your mouth, and continue cycles of CPR until emergency responders arrive.

Important: If you are alone and have not yet called emergency services, provide two minutes of CPR before stepping away to call 911.

Frequently Asked Questions

Why are abdominal thrusts (Heimlich maneuver) not used on infants?
Infants have fragile, developing anatomy where the rib cage does not fully protect the upper abdominal organs. Applying abdominal thrusts can cause severe internal bleeding or laceration to the liver and spleen. Back blows and chest thrusts create adequate airway pressure without risking abdominal organ rupture.
What should I do if my baby is choking on liquid?
Infants frequently gag or cough when milk or formula flows too quickly. If the baby is coughing, sputtering, or crying, their airway is still functional; keep them upright or lean them slightly forward so they can clear it naturally. Only perform back blows and chest thrusts if the infant stops making sound, turns blue, or cannot breathe.
Does my baby need to see a doctor after a choking episode if they seem fine?
Yes. Even if the infant coughs up the item and appears completely recovered, a medical evaluation is recommended. A physician must examine the child to ensure that no foreign fragments were aspirated into the lungs and that the physical maneuvers did not cause soft-tissue or skeletal trauma.
What are the most common choking hazards for infants?
Common infant choking hazards include small, round, or firm foods such as whole grapes, hot dog rounds, nuts, hard candy, and raw vegetables. Non-food items like coins, small toy parts, button batteries, and uninflated latex balloons also present severe choking risks.
