The majority of choking injuries and fatalities occurs in children aged 0–4,<ref>{{Cite journal |last1=Chang |first1=David T. |last2=Abdo |first2=Kaitlyn |last3=Bhatt |first3=Jay M. |last4=Huoh |first4=Kevin C. |last5=Pham |first5=Nguyen S. |last6=Ahuja |first6=Gurpreet S. |date=May 2021 |title=Persistence of choking injuries in children |url=https://linkinghub.elsevier.com/retrieve/pii/S0165587621000781 |journal=International Journal of Pediatric Otorhinolaryngology |language=en |volume=144 |pages=110685 |doi=10.1016/j.ijporl.2021.110685|pmid=33819896 |s2cid=233036815 }}</ref> highlighting the importance for widespread dissemination of the appropriate anti-choking techniques for these age groups.

For infants under 1 year-old, the American Heart Association recommends adapted procedures.<ref>{{Cite journal |last=Wilkins, Lippincott Williams |date=2010-11-02 |title=Editorial Board |journal=Circulation |volume=122 |issue=18_suppl_3 |pages=S639 |doi=10.1161/CIR.0b013e3181fdf7aa|doi-access=free }}</ref> The size of the children's body is the most important aspect in determining the correct anti-choking technique. So the [[Choking#techniques in the first aid protocol against choking|normal first aid techniques against choking]] would be tried in children who are too large for the babies' procedures (or they would be tried as a less appropriated attempt if the rescuer is unable to perform the techniques for babies).

First aid for choking infants alternates a cycle of special back blows (five back slaps) followed by special chest thrusts (five adapted chest compressions). [[File:Heimlich Infant.png|thumb|'''Left:''' 'Back blows for infants', the baby receives the slaps being carefully held and slightly placed upside-down; a support under the chest is recommended.

It is recommended that the baby receive them being slightly leaned upside-down on an inclination. There exist several ways to achieve this:

According to a widely propagated modality: the rescuer sits down on a seat with the baby, and supports the baby with a forearm and its respective hand. The baby's head must be carefully held with that hand (approximately by the face), and kept in a normal position, facing forward, not inclinated. Then the baby's body can be leaned forward upside-down along the rescuer's thighs, and receive the slaps.

As an easier alternative: the rescuer can sit on a bed or sofa, or even the floor, carrying the baby. Next, the rescuer should support the baby's body on the own lap, to lean the baby a bit upside-down at the right or the left of the lap. The baby's head must be in a normal position, facing forward, frontally, and not inclinated. It is always convenient that the baby's chest is supported against something. Then the rescuer would slap the back of the baby.

If the rescuer cannot sit down: at least it is possible to attempt the manoeuver at a low height and over a soft surface. Then the rescuer would support the baby with a forearm and the hand of that side, holding carefully the baby's head with that hand (approximately by the face, but always trying that the baby's head keeps in a normal position, facing forward, not inclinated). The baby's body would be leaned upside-down in that position to receive the slaps. In situations with rescuers who cannot do all of that (as rescuers with disabilities and others), they can still try the normal back blows, supporting the baby's chest with one hand, bending the baby's body, and then giving firm slaps with the other hand.

In the ''chest thrusts manoeuver'', the baby's body is placed lying face up on a surface (it can be the rescuer's thighs, lap or forearm). Then, the rescuer does the compressions pressing with only two fingers on the lower half of the bone that is along the middle of the chest from the neck to the belly (on the chest bone, named [[sternum]], on its part that is the nearest to the belly). Abdominal thrusts are not recommended in children less than one year old because they can cause liver damage.<ref name=":4">{{Cite journal |last=Wilkins |first=Lippincott Williams & |date=2010-11-02 |title=Editorial Board |journal=Circulation |language=en |volume=122 |issue=18 suppl 3 |pages=S639 |doi=10.1161/CIR.0b013e3181fdf7aa |issn=0009-7322 |doi-access=free}}</ref>

The back blows and chest thrusts are ''alternated in cycles'' of five back blows and five chest compressions until the object comes out of the infant's airway or until the infant becomes unconscious.<ref name=":4" />

If choking is unresolved despite these rescue attempts, it is vital that somebody calls to the [[List of emergency telephone numbers|emergency medical services]] and continue first aid until they arrive. An infant can fall unconscious soon, then an anti-choking resuscitation for infants is required (read next).

===== Unconscious infants =====
An ''unconscious'' infant has to be placed face-up on a firm and horizontal surface (as the floor). The baby's head must be in a straight position, facing frontally, because tilting it too much backwards can close the access to the trachea in infants.

A rescuer can then ask for any of the known anti-choking devices, and try it on the unconscious baby. There can be difficulties because of the little size of the infant. The obstruction can be dislodged, but remaining into the mouth, which would need a manual removal. If the baby cannot breath then, or stays in a cardiac arrest, the rescuer must perform a normal cardiopulmonary resuscitation (CPR), as it is described below, but only alternating the 30 compressions and the 2 rescue breaths.

[[List of emergency telephone numbers|Emergency medical services]] must be called, if this has not been done yet.

It can be also convenient that any rescuer asks for a defibrillator near (an AED, as those devices are very common today), just in case it is necessary to treat the baby's heart.

Until emergency services arrive, the American Heart Association<ref name=":4" /> recommends starting (even<ref name=":9" /><ref name=":11" /> with no more delay) an anti-choking cardiopulmonary resuscitation (CPR) adaptive to infants less than one year old (described below). It is a cycle of resuscitation<ref>{{Cite book |last=American Red Cross |title=CPR/AED and First Aid |pages=33 |chapter=Choking – Special Situations}}</ref> that alternates compressions and rescue breaths, like in a normal CPR, but with some differences: 
The rescuer begins by making 30 ''compressions,'' pressing with only two fingers on the lower half of the bone that crosses the middle of the chest from the neck to the belly (on the chest bone, named [[sternum]], on its part that is the nearest to the belly), at an approximate rhythm of nearly 2 per second.

At the end of the round of compressions, the rescuer looks into the mouth for the obstructing object. And, if it is already visible, the rescuer makes a ''try to extract it'' (usually using a finger sweep). The rescuer must not confuse a foreign object with the epiglottis: a cartilaginous flap of the throat. It is possible to try to extract the object without seeing it, always carefully: taking it with the fingers, or using a toothpick (maybe, because almost any other tool would be too wide for a baby), but the current protocols do not recommend extracting the object if it is not visible (a blind extraction), because of the risk to sink it deeper by accident, and because the compressions could move the object outside by themselves (in some cases). A rescuer that already knows that the choking object is a bag (or similar) does not need to see the object before trying to extract it (because there is no risk of sinking it much deeper, and it is easy to detect by using the touch carefully). Anyway, if any removal is tried and takes too much time, it may require alternating it with the chest compressions at some moments, without hindering to the extraction. And, being the object extracted or not in this step, this CPR procedure must pass to the next action and continue until the babies can breathe by themselves or emergency medical services arrive.

In the next step of the CPR, the rescuer makes ''a rescue breath'', covering the baby's mouth and nose simultaneously with the own mouth, and puffing air inside a first time. After that first rescue breath, it is recommended ''tilting the baby's head'' up and down, trying to open a space for the air in that manner, but leaving it approximately straight again, and then giving ''an additional rescue breath'', for the second time''.'' The rescue breaths usually fail while the object is still blocking, but then the rescuer has only to continue with the next step. Anyway, they can enter and reach the lungs, and then the chest of the baby would be seen rising. If a rescue breath arrived there, it is because the object has been moved to an unknown position that leaves some open space, so it can be useful making the next rescue breaths more softly to avoid moving the object to a new blocking position again, and, in case of those soft rescue breaths are not successful, increasing the strength of blowing in the next ones. The bodies of the babies are delicate, and, when the airway is not clogged, only a little strength in blowing is enough to fill their lungs. The baby's colour would improve after some successful rescue breaths. After the rescue breaths, the rescuer has to return to the 30 initial compressions, repeating the same resuscitation cycle again, continually, until the choking baby regains consciousness and breathe normally, or until the object is extracted but a defibrillation is needed to solve a cardiac arrest (read below).

''Defibrillation'' can also be needed, because a choking infant that is already unconscious can suffer a cardiac arrest at any moment, due to several possible causes.<ref name=":13" /> So it is convenient to ask around for a defibrillator (AED device), for trying a defibrillation on a baby that remains in cardiac arrest after having extracted the stuck object (only if the object has been extracted). Those defibrillators are easy to use, as they emit their instructions with voice messages. One of the pads of the defribrillator (any of them) is attached to the baby's chest, and the other pad to the baby's back.
