Why Does My Baby Suddenly Choke? Causes and First Aid

A baby may suddenly cough or gag when milk flows faster than they can swallow, saliva collects in their mouth, or a small piece of food reaches the back of their throat. Gagging and choking are different: a baby who is coughing forcefully or making sounds is moving air, while a baby who cannot cry, cough effectively, or breathe may have a blocked airway.

If your baby is coughing effectively, stay with them, let them cough, and watch their breathing closely; do not put your fingers in their mouth unless you can clearly see an object you can easily remove. If your baby cannot breathe or make sounds, have someone call 911, give five back blows followed by five chest thrusts, and repeat until the object comes out or help arrives; if your baby becomes unresponsive, start infant CPR and follow the dispatcher’s instructions. Do not use abdominal thrusts on a baby under 1 year old.

If coughing or sputtering happens during bottle-feeding, pause the feeding, hold your baby upright, and consider whether the nipple flow is too fast; during breastfeeding, a strong milk letdown may also make it hard for a baby to keep up. Repeated episodes, trouble feeding, or breathing changes deserve a call to your pediatrician rather than an assumption that your baby will simply outgrow them.

Check the product’s listed specifications when evaluating when it happens during feeding.

Get emergency help for blue or gray coloring, severe breathing difficulty, unusual limpness, or a baby who cannot cough or cry. Even if an episode passes, contact your pediatrician if coughing continues after a feed, breathing sounds wet or wheezy, or your baby develops a fever or seems unwell.
