Pediatric first aid is the immediate care given to infants and children who are injured or suddenly ill, using techniques specifically adapted for smaller bodies. Children are not just small adults. Their narrower airways, thinner skin, lower blood volume, and different body proportions all require modified approaches to choking, CPR, burns, and other emergencies. Knowing these differences can be the factor that keeps a minor injury from becoming a serious one.
Why Children Need Different First Aid
Several key physical differences make standard adult first aid techniques inappropriate, or even dangerous, for children. A child’s airway is significantly narrower than an adult’s, which means it blocks more easily and requires gentler rescue breaths during resuscitation. Children also have less total blood in their bodies, so even what looks like a small amount of bleeding can lead to shock much faster than it would in an adult. Their skin is thinner and burns more quickly at lower temperatures. And because their organs are less protected by muscle and fat, internal injuries can occur from forces that an adult body would absorb without trouble.
These aren’t minor footnotes. They change nearly every first aid technique you’d use, from how hard you press during chest compressions to how you clear a blocked airway.
CPR for Infants and Children
Cardiopulmonary resuscitation follows the same basic principle at any age: push hard on the chest to keep blood circulating, and deliver breaths to supply oxygen. But the mechanics change dramatically based on the child’s size.
For infants under one year, you use just two fingers placed on the breastbone to deliver chest compressions. Press down about 1.5 inches, which is roughly one-third to one-half the depth of the infant’s chest. For children between one and eight years old, you switch to one or two hands (depending on the child’s size) and compress about 2 inches deep. In both cases, the ratio is the same: 30 compressions followed by 2 rescue breaths. When giving those breaths, use only enough air to make the chest visibly rise. Overinflating a child’s lungs can cause injury.
If you’re alone with a child who isn’t breathing, perform CPR for two minutes before calling emergency services. This differs from the adult protocol, where you call first. The reason is that cardiac arrest in children is usually caused by a breathing problem rather than a heart problem, so those initial minutes of CPR are critical.
How to Help a Choking Child
Choking is one of the most common pediatric emergencies, and the response depends entirely on the child’s age.
Babies Under One Year
Never use abdominal thrusts (the Heimlich maneuver) on an infant. Instead, sit down and lay the baby face down along your forearm or thigh, supporting their head and neck with your hand. Deliver up to five firm back blows with the heel of your hand between the shoulder blades, checking after each one to see if the object has come out. If the airway is still blocked, turn the baby face up along your thighs with their head lower than their body. Place two fingers in the center of their chest, just below the nipple line, and give up to five sharp chest thrusts. Alternate between back blows and chest thrusts until the object clears or help arrives.
Children Over One Year
For older children, start with back blows. Lean the child forward (or lay a small child face down across your lap) and deliver up to five back blows. If that doesn’t work, move to abdominal thrusts: stand or kneel behind the child, place your fist between their navel and ribs, and pull sharply inward and upward. Repeat up to five times, checking between each thrust. Avoid pressing on the lower ribcage, as this can cause internal damage.
Treating Burns
Because children’s skin is thinner, burns tend to be deeper and more serious than they would be on an adult exposed to the same heat source. The immediate response is the same regardless of severity: cool the burned area under cool running water for a full 20 minutes. This remains effective if started within three hours of the burn, but sooner is always better.
Never apply ice to a child’s burn. Ice can damage already injured tissue and trigger hypothermia in small children. Avoid butter, toothpaste, or any home remedy. Once cooled, loosely cover the burn with plastic cling wrap laid lengthwise over the area. Don’t wrap it around a limb or digit, as swelling can make a tight wrap dangerous. Don’t apply cling wrap to the face.
A burn that blisters, looks white or waxy, or covers an area larger than the child’s palm needs professional medical attention. Burns on the face, hands, feet, joints, or genitals also warrant a trip to the emergency department regardless of size.
Managing Seizures
Febrile seizures, triggered by a rapid rise in body temperature, are the most common type of seizure in young children. They look alarming but typically stop on their own within a couple of minutes. Your job is to keep the child safe while the seizure runs its course.
Place the child on their side on a soft, flat surface where they can’t fall. Move hard or sharp objects out of reach. Loosen any tight clothing. Start timing the seizure from the moment you notice it. Do not restrain the child, try to hold them still, or put anything in their mouth. Once the seizure stops, stay close, keep them on their side, and comfort them as they come around.
Call emergency services if the seizure lasts longer than five minutes, if the child has repeated seizures, or if the child doesn’t seem to be recovering quickly after a shorter episode.
Severe Allergic Reactions
Anaphylaxis can be harder to recognize in young children, especially those who can’t yet describe what they’re feeling. In infants, watch for sudden drooling, going pale and floppy, or a noticeable change in the character of their cry. Older children may complain of a tight throat, show hives or facial swelling, or start wheezing.
If a child has a prescribed epinephrine auto-injector, use it immediately. The junior version is designed for children roughly 15 to 44 pounds (about 7.5 to 20 kg), generally those under five years old. Inject it into the outer thigh, through clothing if necessary, and hold it in place for several seconds. Then call emergency services, even if the child seems to improve. Anaphylaxis can return after the medication wears off.
Poisoning and Ingestion
Young children explore with their mouths, making accidental poisoning a constant risk around household cleaners, medications, and even certain plants. If you suspect a child has swallowed something toxic, do not try to make them vomit. Inducing vomiting can cause additional damage, especially with caustic substances.
If the child has collapsed, is having a seizure, is struggling to breathe, or can’t be woken up, call 911 immediately. For situations that seem less urgent, you can call Poison Control at 1-800-222-1222 or use their online tool at poison.org. Both are free, staffed by experts, and available around the clock. Have the container or product label nearby so you can describe exactly what the child ingested and approximately how much.
Building a Pediatric First Aid Kit
A well-stocked kit tailored for children should go beyond the basics found in a standard adult first aid box. Include adhesive bandages in multiple small sizes, sterile gauze pads, medical tape, child-safe scissors, a digital thermometer, disposable gloves, a cold pack, and a list of emergency phone numbers including Poison Control. If your child has a known allergy or medical condition, keep their auto-injector or relevant medication in the kit along with a medical alert bracelet or necklace as a backup.
The CDC recommends keeping at least a two-week supply of any specialized medical items your child uses, such as syringes, nasal cannulas, or specific bandaging supplies. Store the kit somewhere adults can reach quickly but children cannot access on their own, and check it every few months to replace expired items.
Consent and Legal Protections
A common concern for caregivers, teachers, and bystanders is whether they’re legally allowed to provide first aid to someone else’s child. In emergency situations, the doctrine of implied consent applies: if a parent or guardian isn’t present and a child needs immediate care, the law assumes that a reasonable parent would consent to life-saving treatment. This principle is reinforced by the Emergency Medical Treatment and Labor Act, which requires that anyone, regardless of age, receive emergency screening and stabilization at a hospital.
Good Samaritan laws in most states provide additional protection for bystanders who act in good faith to help an injured child, as long as they don’t act recklessly or beyond their training. If you’re in a role where you regularly supervise children, whether as a teacher, coach, or childcare provider, completing a certified pediatric first aid course gives you both the skills and the legal standing to act with confidence.
