Infant CPR and Choking First Aid: What Every Parent Must Know

The most common thing parents say after a child’s breathing emergency is, “I didn’t know what to do — I panicked.” Panic is normal. Preparation is what replaces it with action. This is a clear, step-by-step guide to infant choking first aid and CPR for babies under 12 months old. Read it, bookmark it, and share it with every caregiver who watches your baby — and then, importantly, take a hands-on class. The American Heart Association and Red Cross run them everywhere, and nothing replaces practicing on a mannequin with an instructor watching your hands.

In any breathing emergency, the priority is to get help coming and act fast — this article is a guide, not a substitute for certified training or emergency medical care.

A Note on Age

The techniques here are for infants under 1 year. Once your child turns one, the protocol changes slightly (child CPR), so if you care for an older child, take a class that covers it — the key differences are summarized in a table below.

Why Infants Stop Breathing or Choke

Babies explore the world with their mouths, and they have tiny airways that block easily. Common choking hazards include small toys or parts; coins, buttons, and (especially dangerous) button batteries; foods like hot dogs, whole grapes, nuts, popcorn, hard candy, and blobs of peanut butter; latex balloons; and household items like pen caps. The AAP advises keeping small objects away from infants and cutting food into pieces no larger than half an inch — more in our guide to choking hazards and food safety.

Unlike adults, infants rarely have a primary heart problem. When a baby’s heart stops, it’s almost always because they stopped breathing first — from choking, suffocation (unsafe sleep, soft bedding), drowning (even in an inch or two of water), a respiratory infection, electric shock, or trauma. That’s the key insight: if you restore breathing quickly, the heart often follows.

Is the Baby Actually Choking?

This is the crucial first judgment. If your baby is coughing forcefully, crying, or making noise, their airway is only partly blocked — let them cough, stay close, and be ready, but don’t interfere, because coughing is the most effective way to clear it.

If your baby is silent, cannot cry or cough, is making weak high-pitched squeaks, or is turning blue, the airway is fully blocked. Act immediately with the steps below.

Choking First Aid: Back Blows and Chest Thrusts

This is the sequence for a conscious, choking infant. (Never use abdominal thrusts — the Heimlich — on a baby under 1; it can injure their organs.)

1. Position the baby. Hold them face-down along your forearm, head lower than the chest, supporting the head and jaw with your hand (never covering the mouth). Rest your arm on your thigh for support.
2. Give 5 back blows. With the heel of your free hand, deliver five firm blows between the shoulder blades — strong and controlled, enough to jolt the object loose.
3. Turn the baby face-up. Supporting the head and neck, roll them along your other arm, keeping the head lower than the chest.
4. Give 5 chest thrusts. Place two fingers in the center of the chest, just below the nipple line, and push down about 1.5 inches (4 cm) in five quick, distinct thrusts to force air (and the object) up.
5. Repeat cycles of 5 back blows and 5 chest thrusts until the object comes out, or the baby becomes unconscious.

If a Choking Baby Becomes Unconscious

If the baby goes limp and unresponsive, everything shifts to CPR:

1. Call for help. If someone is with you, have them call 911 (or your local emergency number) immediately. If you’re alone, do CPR for 2 minutes first, then call.
2. Lower the baby to a firm, flat surface — the floor or a table — on their back.
3. Look in the mouth. If you can clearly see the object, remove it with a gentle finger sweep. Never do a blind sweep — you can push it deeper.
4. Start CPR, beginning with chest compressions. The compressions themselves may dislodge the object.

Infant CPR: Unresponsive, Not Breathing

For a baby who is unconscious and not breathing (or only gasping):

1. Check responsiveness and breathing. Tap the sole of the foot and shout; look for chest movement. Take no more than 10 seconds. If unresponsive and not breathing normally, begin CPR.
2. Call for help. If someone is with you, they call 911 while you start. If you’re alone, do 2 minutes of CPR first, then call.
3. Position the baby on a firm, flat surface, and bare the chest so you can place your hands correctly.
4. Give 30 chest compressions. Two fingers in the center of the chest, just below the nipple line. Push down about 1.5 inches (one-third the depth of the chest) at a rate of 100–120 per minute (the tempo of “Stayin’ Alive”), letting the chest fully recoil between each so the heart can refill.
5. Give 2 gentle breaths. Open the airway to a neutral or slight “sniffing” position — do not tip an infant’s head far back, as it can block the airway. Cover the baby’s mouth and nose with your mouth, and give a small puff over about 1 second, just enough to make the chest visibly rise. If it doesn’t rise, reposition the head and try again; if it still doesn’t, treat it as choking.
6. Repeat cycles of 30 compressions and 2 breaths until the baby moves or breathes, trained help takes over, or you’re too exhausted to continue.

Infant vs. Child CPR: The Key Differences

After the Baby Recovers

If your baby starts breathing and responding again: gently place them on their side (the recovery position) to keep the airway clear and let fluids drain; still call 911 and get them evaluated even if they seem fine, because objects can lodge in the lungs and CPR can cause internal injury; keep them warm; and stay with them, watching their breathing and color until help arrives.

Prevention Is the Best First Aid

Choking: keep small objects out of reach, cut food small, avoid high-risk foods, and check toys for small parts. Suffocation: follow safe sleep — always on the back, firm mattress with a fitted sheet, a bare crib, and no bed-sharing (especially if you smoke, drink, or take sedating medication). Drowning: never leave a baby alone near water even for a second, empty tubs and buckets right away, and use toilet locks. And the biggest one: learn these skills before you ever need them. Our newborn safety checklist and bath safety guide round out the home basics.

Take a Hands-On Class

Reading this is a start; bookmarking and sharing it is smart. But nothing replaces practicing on a mannequin with a certified instructor watching your hands. The American Heart Association, the Red Cross, and many hospitals offer infant CPR classes — find one and take it, then refresh it when your baby becomes a toddler, since the skills change. Most parents will never need infant CPR. But if you do, you won’t have time to look it up; you’ll have only your hands and your memory. Make sure your hands know what to do.

Quick Reference

Choking & conscious: 5 back blows (face-down, head low) → 5 chest thrusts (face-up, two fingers, center chest) → repeat until the object is out or the baby is unconscious.

Choking & becomes unconscious: call 911 (or after 2 min if alone) → look in mouth, remove only if visible → start CPR with compressions.

Unconscious & not breathing: tap & shout → call 911 (or after 2 min if alone) → 30 compressions (2 fingers, ~1.5 in, 100–120/min) → 2 gentle breaths (mouth & nose, chest rises) → repeat.

Stop when: the baby moves or breathes, trained help takes over, or you physically can’t continue.
