The airway is partly open and working. Stay right there, keep them calm, and let them cough. Coughing is the most effective way to clear the airway.
Don't slap the back, don't hold them upside down, and don't sweep a finger through the mouth blindly. Any of these can turn a partial blockage into a complete one.
Alternate the two moves until the object comes out or the child stops responding. Never do abdominal thrusts on a baby under 1; their liver and spleen sit too high and are easy to injure.
If no one has called 911 yet, call now on speaker. Before giving breaths, look in the mouth. Remove the object only if you can actually see it. Never do a blind finger sweep; it can push the object deeper.

Watch once now, before you ever need it. Hands positioned wrong is the most common mistake.
This is the scenario you'll actually see at your dinner table, probably this week. A baby learning to eat gags constantly. It looks alarming and it's completely normal. The gag reflex sits farther forward in a baby's mouth than in yours, on purpose. It's the built-in safety system pushing food forward before it gets anywhere near the airway.
The rule that keeps you calm: loud and red, let them go ahead. Silent and blue, it's up to you. If you jump in during normal gagging, you can startle the baby into inhaling the food and cause the emergency you were trying to prevent.
Before it ever happens
Almost every choking death in young children is preventable. Prevention comes down to three things: starting solids when your baby is actually ready, preparing food correctly for their age, and keeping the right objects out of reach.
The AAP recommends introducing solid foods around 6 months. The calendar matters less than the readiness signs: your baby can sit with minimal support, has steady head control, opens their mouth and leans in for food, and has lost the tongue-thrust reflex that automatically pushes food back out. A baby who meets those milestones has the motor coordination to manage food safely. A baby who doesn't, doesn't, regardless of age.
Start with textures that dissolve or mash easily and progress as chewing skills develop. Whether you do purees, baby-led weaning, or a mix matters far less than food size and texture. Both approaches are safe when the food is prepared correctly.
"I did baby-led weaning with my own daughter, and I still practiced back blows on a mannequin the week before we started. Not because I expected to need them. Because the version of me that knows the steps cold is calmer at the dinner table, and a calm parent lets normal gagging resolve instead of turning it into an emergency."— Dr. Brandon
The dangerous foods share a shape: round, firm, slippery, or exactly airway-sized. A grape is almost a perfect anatomical plug for a toddler's trachea. These rules apply until at least age 4, when chewing and swallowing mature.
| Food | What to do |
|---|---|
| Grapes, cherry tomatoes | Quarter lengthwise. Never serve whole, never just halve. |
| Hot dogs, sausages | Slice lengthwise first, then into small pieces. No coin-shaped rounds. |
| Whole nuts, seeds | Not before age 4. Ground or as smooth butters only. |
| Nut butters | Thin with water or spread paper-thin. Never by the spoonful. |
| Popcorn, hard candy, gum | Not before age 4. No safe way to modify these. |
| Raw carrot, raw apple | Grate, thinly slice, or cook soft for babies and young toddlers. |
| Marshmallows | Skip them for young children. They mold to the airway. |
General rule for toddlers: pieces no bigger than half an inch, served to a child who is seated and supervised. No eating in the car, no eating while walking or running, no throwing food into the mouth. Most of the choking events I see didn't happen at a calm dinner table.
In older infants and toddlers, small objects cause a large share of choking events: coins, marbles, button batteries, pen caps, small toy parts, and broken balloon pieces. Latex balloons deserve special mention because a torn piece conforms to the airway and is very hard to dislodge. The quick screen: anything that fits through a toilet paper tube can block a small child's airway.
A swallowed button battery is an emergency even if your child looks completely fine. It can burn through the esophagus in as little as two hours. Go to the ER immediately. Don't wait for symptoms, don't induce vomiting, don't wait to call your pediatrician first.
For parents who want the source, not the summary
In October 2025, the American Heart Association and the American Academy of Pediatrics jointly published the first full revision of CPR and emergency care guidelines since 2020. The choking guidance changed in a way worth knowing about.
What changed: for children over 1, the old advice was abdominal thrusts alone. The new sequence leads with 5 back blows, then alternates with 5 abdominal thrusts. The infant sequence (back blows alternating with chest thrusts) stays the same, now specifying the heel of one hand for the chest thrusts.
Honest read on the evidence: this change isn't driven by a big new trial. High-quality pediatric choking data barely exists, for the obvious reason that you can't randomize choking children. The committee weighed observational data suggesting back blows work well, plus a practical argument: making the child sequence mirror the infant one means one pattern to remember under stress. Reasonable people could have kept the old sequence. I follow the new one, and it's what I'd do with my own kid.
Only if you can clearly see the object and easily grab it. A blind finger sweep can push it deeper and turn a partial blockage into a complete one.
They can have a role as a last resort when back blows and thrusts haven't worked. They are not a replacement for the standard first aid sequence, and having one in the drawer is not a substitute for knowing the steps.
Call your pediatrician after any real choking event, even one that resolved. And seek care urgently if there's drooling, trouble swallowing, a lasting cough, or noisy breathing afterward; those can mean something is still lodged lower down.
If you remember nothing else
Save the card and send it to whoever watches your kid: grandparents, babysitters, your partner. The steps only help if the person in the room knows them.
