In an emergency, seconds count — and a calm, trained caregiver makes the difference. Every parent and caregiver should know the basics of infant choking response, CPR, and when to call for help. This guide is an overview to build awareness and prompt you to get certified; it does not replace a hands-on class, which is the only way to truly learn these skills.
Choking: back blows and chest thrusts
If a baby under one can still cough, cry, or breathe, let them cough — coughing is the most effective way to clear an airway. If they can’t make sound or breathe: lay them face-down along your forearm with the head lower than the chest and give five firm back blows between the shoulder blades; then turn them face-up and give five chest thrusts with two fingers on the breastbone. Alternate until the object clears. If they go unresponsive, start CPR and call 911. Never sweep blindly in the mouth — it can push the object deeper.
Infant CPR basics
If a baby is unresponsive and not breathing normally: call 911 (or have someone call) and begin CPR. Use two fingers (or two thumbs encircling the chest) to compress the center of the chest about 1.5 inches deep, fast (about 100–120/minute). After 30 compressions, give 2 gentle breaths covering the nose and mouth, watching for the chest to rise. Continue 30:2 until help arrives or the baby revives. This is gentler and faster than adult CPR — but practice it in a real class.
When to call 911
Call emergency services immediately for a baby who is not breathing or gasping, unresponsive, turning blue or gray, having a seizure, bleeding severely, showing a serious allergic reaction (facial/throat swelling, breathing trouble), or after a major fall with loss of consciousness or repeated vomiting. Trust your instinct — it’s always right to call when you fear for your baby’s life.
Common situations: fever, falls, burns
Fever: in a baby under 3 months, any temperature of 100.4°F (38°C)+ is an emergency — call right away. Falls: watch for loss of consciousness, repeated vomiting, or behavior changes, which need urgent care. Burns: cool a minor burn under cool (not ice-cold) running water for several minutes, cover loosely, and never apply butter or ointments; seek care for anything beyond a small superficial burn. Poisoning: call Poison Control (1-800-222-1222 in the U.S.) immediately — don’t induce vomiting unless told to.
Build a first-aid kit
Stock and keep accessible: infant acetaminophen (and ibuprofen if over 6 months) with a dosing syringe, a digital thermometer, saline drops and a bulb syringe, bandages and gauze, antiseptic wipes, tweezers, a cold pack, and a card with your pediatrician’s number and Poison Control. Add any prescribed emergency medication and check expiration dates periodically.
The bottom line
Know the choking response (back blows + chest thrusts for under-1), infant CPR (two fingers, 30:2), and the clear triggers to call 911. Keep Poison Control handy and a stocked kit ready. Most importantly: take a hands-on infant CPR and first-aid class and refresh it — reading builds awareness, but practice saves lives.

Frequently asked questions
What do I do if my baby is choking?
For a baby under 1 who can’t cough, cry, or breathe: give 5 firm back blows between the shoulder blades (baby face-down along your forearm, head lower than chest), then 5 chest thrusts (two fingers on the breastbone). Alternate until the object comes out or the baby becomes unresponsive — then start CPR and call 911. If the baby is coughing forcefully, let them cough. Never do blind finger sweeps.
How is infant CPR different from adult CPR?
For infants you use two fingers (or two thumbs encircling the chest) for compressions about 1.5 inches deep, give gentle breaths covering the nose and mouth, and use a 30:2 compression-to-breath ratio (30 compressions, 2 breaths) if alone. The technique is gentler and faster to learn hands-on — a certified class is strongly recommended.
When should I call 911 for my baby?
Call immediately for: not breathing or gasping, unresponsiveness, blue or gray color, a seizure, severe bleeding that won’t stop, a serious allergic reaction (swelling, trouble breathing), a major fall with loss of consciousness or vomiting, or any situation where you fear for the baby’s life. When in doubt, call.
What should be in a baby first-aid kit?
Infant acetaminophen (and ibuprofen if over 6 months) with a dosing syringe, a digital rectal thermometer, saline drops and a bulb syringe, adhesive bandages and gauze, antiseptic wipes, tweezers, a cold pack, infant-safe sunscreen, your pediatrician’s and Poison Control numbers, and any prescribed emergency meds (e.g., epinephrine if advised).
Do I really need a first-aid class?
Yes — reading is not enough for choking and CPR, which require muscle memory under stress. Take a hands-on infant CPR and first-aid course (Red Cross, AHA, or a hospital program). Refresh every couple of years and make sure other caregivers are trained too.
