Baby Choking Emergency Signs

Severe choking can be silent. Treat inability to breathe, cry, or make sound, an ineffective cough, blue or gray color, limpness, or loss of responsiveness as an emergency. Do not wait for a complete checklist, a video call, or a pediatrician appointment when the airway may be blocked.
Summary
Call the local emergency number and begin the infant choking response you learned in a current certified course, following the dispatcher. If the baby becomes unresponsive, use your trained infant CPR sequence and an AED if directed and available. Do not perform a blind finger sweep, shake the baby, suspend the baby by the feet, give water or food, or drive alone instead of activating emergency services when urgent help is indicated.
Separate forceful cough from ineffective cough
A forceful cough with audible air suggests the baby is moving air; remain close, keep observing, and avoid interfering with a blind finger sweep. An ineffective or absent cough together with inability to breathe, cry, or make sound signals a possible severe obstruction. Blue or gray color, limpness, or loss of responsiveness makes the situation immediately urgent. If you cannot confidently determine airflow, call emergency services and follow the dispatcher rather than offering water, more food, or an improvised remedy.
Prepare a trained emergency response
Every regular caregiver should take a current certified infant first aid and CPR course, know the local emergency number, and understand where the phone and address details are kept. Practice on a training manikin, never on a real baby. During suspected severe choking, call emergency services and use the age-appropriate sequence learned in training while following the dispatcher. If the baby becomes unresponsive, transition to the trained infant CPR response and use an AED if directed and available.

Avoid actions that waste time or cause harm
Do not put fingers blindly into the baby's mouth, shake the baby, hold the baby upside down by the feet, or give water, oil, or more food. Do not film the event, search social media, or wait for a clinic appointment when breathing may be blocked. Do not drive alone instead of activating emergency services when urgent help is indicated. After any choking episode that required intervention, or when coughing, breathing, swallowing, voice, behavior, or color remains abnormal, follow emergency or pediatric advice even if the object seems to have come out.
