If your baby is choking RIGHT NOW, scroll to the first aid section below or call SAMU 192 (Brazil's emergency number).
Choking is one of the most terrifying experiences for any parent — and knowing what to do in those first seconds can save your child's life. In this guide, I will walk you through step-by-step first aid for choking, how to tell the difference between choking and gagging (which is normal!), which foods pose the greatest risk, and how to prevent it. If you are starting solid food introduction, this is essential reading. For general pediatric care information in Brazil, see our expat guide to pediatric care.
FIRST AID: Baby Choking
If the baby CANNOT cough, cry, or breathe, act IMMEDIATELY. If unconscious, call SAMU 192 and begin CPR.
Baby UNDER 1 Year Old
Place baby face-down on your forearm
Support the baby's head with your hand, keeping the head lower than the chest. The chin can rest between your thumb and index finger.
Give 5 firm back blows
Using the heel of your hand, deliver 5 blows between the shoulder blades. Be firm but not excessive.
Turn baby face-up
Support the head and neck, keeping the head lower than the chest.
Give 5 chest thrusts
Using 2 fingers (index and middle) on the center of the chest, just below the nipple line. Compress about 4 cm (1.5 inches) deep.
Alternate: 5 back blows + 5 chest thrusts
Repeat until the object comes out, the baby coughs/cries, or becomes unconscious.
Child OVER 1 Year Old — Heimlich Maneuver
Stand or kneel behind the child
Wrap your arms around the child's waist.
Position your fist
Place your fist (thumb side in) between the belly button and the base of the breastbone (pit of the stomach).
Perform abdominal thrusts
Grasp your fist with the other hand and press inward and upward with quick, firm movements.
Repeat until the object is expelled
Continue until the foreign body comes out or the child becomes unconscious.
If the Child Becomes Unconscious
Call SAMU 192 IMMEDIATELY (or ask someone to call).
• Place baby/child on a firm, flat surface
• Begin CPR: 30 chest compressions + 2 rescue breaths
• After each cycle, look inside the mouth — if you can see the object, remove it with a finger sweep
• NEVER blindly sweep for an object you cannot see — you may push it deeper
• Continue CPR until SAMU arrives
Emergency numbers in Brazil:
• SAMU: 192 (ambulance / medical emergency)
• Bombeiros (Fire Department): 193
Nearest pediatric ERs: Hospital Sabara (Higienopolis), Hospital Albert Einstein (Morumbi)
What You Should NEVER Do During Choking
- • NEVER blindly put your finger in the mouth — you may push the object deeper
- • NEVER hold the baby upside down by the feet and shake
- • NEVER give water or any liquid during choking
- • NEVER perform abdominal thrusts (Heimlich) on a baby under 1 year — risk of liver injury
- • If the baby is coughing forcefully, DO NOT intervene — coughing is the most effective defense mechanism

Talk to the PediatricianChoking vs. Gagging: How to Tell the Difference
This is the most common question from parents starting solid food introduction. The gag reflex is a NORMAL protective mechanism in babies — and it is very different from actual choking. Understanding the difference prevents unnecessary panic while ensuring you recognize a true emergency.
| Sign | Gagging (NORMAL) | Choking (EMERGENCY) |
|---|---|---|
| Sound | Loud — coughing, retching, gagging sounds | Silent — little or no sound |
| Coughing | Strong, effective cough | No cough or very weak cough |
| Skin color | Red face (normal during gagging) | Blue/purple (cyanosis) — especially lips and extremities |
| Breathing | Can breathe between gag episodes | Cannot breathe |
| Crying | May cry afterward | Cannot cry |
| Eyes | Watery eyes (normal) | Wide eyes, panicked expression |
| What to do | Do not intervene — let baby resolve it | Act immediately — first aid + call SAMU 192 |
Gagging Is Normal (and Expected!)
The gag reflex is especially active between 6 and 8 months, when babies start exploring solid foods. It is a protective mechanism that pushes large food pieces forward, preventing them from reaching the airway. Over time, this reflex becomes less sensitive. Do not remove food from the baby's mouth during a gag — this can interfere with feeding development. Stay calm, maintain eye contact, and show the baby your confidence.
Most Common Causes of Choking in Babies and Children
According to the Brazilian Pediatric Society (SBP), the American Academy of Pediatrics (AAP), and the American Red Cross, the most common causes include:
Foods
- • Whole grapes and cherry tomatoes
- • Hot dogs/sausages (cylindrical shape)
- • Popcorn
- • Whole peanuts and tree nuts
- • Raw carrots and hard apple pieces
- • Hard candy and gum
- • Large chunks of meat
- • Marshmallows
Small Objects
- • Coins
- • Button batteries
- • Small toy parts
- • Buttons
- • Pen caps
- • Marbles
- • Deflated balloons
Milk (Feeding)
- • Incorrect position during breastfeeding
- • Forceful milk flow (oversupply)
- • Bottle nipple hole too large
- • Baby lying completely flat
- • Gastroesophageal reflux
- • Feeding while sleeping or crying
Foods: Dangerous Shape vs. Safe Shape
The problem is rarely the food itself — it is the shape and preparation. The table below shows how to prepare foods safely for each stage of food introduction:
| Food | Dangerous Shape | Safe Shape |
|---|---|---|
| Grapes | Whole or halved (cross-cut) | Quartered lengthwise or mashed |
| Hot dogs | Round slices (cylindrical shape) | Cut lengthwise into thin strips |
| Carrots | Raw coins or hard sticks | Cooked until soft (mashable with fork) |
| Apples | Raw hard pieces | Cooked, baked, or finely grated |
| Peanuts/nuts | Whole or in large pieces | Smooth butter/paste or finely ground — always watch for food allergies |
| Cherry tomatoes | Whole | Quartered lengthwise |
| Meat | Large, tough chunks | Shredded, ground, or soft strips |
10 Tips to Prevent Choking
Prevention is the best strategy. These recommendations are based on guidelines from the AAP, SBP, and the American Red Cross:
Always supervise meals
Never let a baby or young child eat alone. Active adult supervision is the single most effective measure against choking.
Child should be seated upright while eating
Never offer food while the child is lying down, walking, running, or in a car. Use a high chair.
Cut food correctly
Round foods should be cut lengthwise (not cross-cut). See the table above for safe shapes by age.
Respect age-appropriate foods
Solid food introduction starts at 6 months. Avoid high-risk foods (popcorn, whole nuts, hard candy) until at least 4 years old.
Correct position during feeding
Keep the baby semi-upright during breastfeeding or bottle-feeding. Never feed completely flat. If you have breastfeeding difficulties, seek guidance.
Keep small objects out of reach
Keep coins, button batteries, marbles, balloons, and small parts away from children. A practical rule: if it fits inside a toilet paper roll, it is a choking risk for children under 3.
Age-appropriate toys
Follow age labels on toys (INMETRO in Brazil, CPSC in the US). Keep older siblings' toys separate from the baby's.
Teach proper chewing
Encourage your child to chew slowly and swallow before putting more food in the mouth. Model this during family meals.
Avoid distractions during meals
No TV, tablets, or active play during meals. Laughing, crying, or running with food in the mouth significantly increases the risk. See our guide on picky eating for distraction-free meal tips.
Take a first aid course
Every caregiver — parents, grandparents, nannies — should know how to perform choking first aid. See course options below.
Baby-Led Weaning (BLW) and Choking: What the Science Says
Baby-Led Weaning (BLW) — where babies eat finger foods from the start of food introduction — raises many safety concerns. Here are the facts:
Scientific Evidence on BLW and Choking
• BLISS Study (2016): BLW with proper guidance did NOT increase choking risk compared to traditional spoon-feeding.
• Systematic review (Pediatrics, 2018): No difference in choking incidence between BLW and traditional feeding when parents received guidance on safe foods.
• Gagging IS more frequent with BLW, which can alarm parents, but it is different from choking and is actually protective.
• Conclusion: BLW is safe when done correctly — with age-appropriate food shapes, constant supervision, and knowledge of first aid.
BLW Safety Rules
- • Foods should be soft enough to mash between your fingers (thumb and index finger test)
- • "Finger food" shaped sticks, about the size of an adult index finger, for babies 6 to 9 months
- • Avoid round, hard, and slippery foods
- • Baby should always be seated upright in a high chair, never reclined
- • Supervise every meal from start to finish
- • All caregivers should know choking first aid
When to Go to the Emergency Room After Choking
Even if your baby appears to have recovered, there are situations that require medical attention. If in doubt, learn when to take your baby to the pediatrician.
Warning Signs After a Choking Episode — Go to the ER
- • Persistent coughing or wheezing that does not resolve
- • Difficulty breathing or noisy breathing
- • Fever in the hours following the choking episode
- • Refusing to eat after the episode
- • Excessive drooling (may indicate a foreign body stuck in the esophagus)
- • Chest or throat pain
- • Repeated vomiting
- • Suspicion that the object was swallowed but not expelled (may be in the esophagus or stomach)
If the child swallowed a button battery or a sharp object, go to the ER IMMEDIATELY — these are surgical emergencies.
First Aid Courses in Sao Paulo
Knowing the theory is important, but practicing the maneuvers in person makes all the difference. I recommend that every family take a pediatric first aid course. In Sao Paulo, there are excellent options (some offer courses in English):
Hospital Albert Einstein
Offers Basic Life Support (BLS) courses for non-professionals, with a focus on pediatric emergencies. Some classes available in English.
Hospital Sabara (Children's Hospital)
A leading pediatric hospital that periodically offers first aid workshops for parents.
Cruz Vermelha Brasileira (Brazilian Red Cross - SP)
First aid courses with a specific module on choking in babies and children. In-person with mannequin simulation. Courses in Portuguese.
Corpo de Bombeiros (Fire Department - SP)
Free first aid courses open to the community. Check the nearest fire station for schedules. Courses in Portuguese.
My Advice as a Pediatrician
I know that the fear of choking is one of the biggest anxieties for parents, especially during the food introduction phase. But do not let fear hold you back: with information and preparation, you can offer food safely and confidently.
During consultations, I guide each family on age-appropriate food cuts, demonstrate choking first aid maneuvers, and answer all questions about safe feeding. If your baby is at the developmental stage of exploring solid foods, let us talk. If you are new to Brazil, our English-speaking pediatrician page has more information.
Remember: preparation and calm are your best tools. And when in doubt, SAMU 192.
