After completing first two rescue breath check if the infant has a pulse by placing your index and middle fingers on the inside of the middle arm, between the shoulder and elbow. 

Difference 4:  Chest Compressions

When performing compressions, place 2 fingers on the breastbone (see video for more detail)-- just below the nipples and make sure not to press at the very end of the breastbone.  Keep your other hand on the infant's forehead, keeping the head tilted back.

Difference 5:  Depth of Compressions

Press down on the infant's chest so that it compresses about 1/3 to 1/2 the depth of the chest.

Before proceeding with Infant CPR:

• Make sure you are not in any danger
• Make sure the victim is not in danger
• Avoid moving the victim unless there is in immediate danger or you are preparing for CPR
• Assess the surroundings for any people who can help
• Make sure you are aware of your location (for ex. floor in the building, etc), to help emergency responders locate you
• Position yourself next to the infant, and determine if the victim is responsive by tapping/flicking the victim on the foot several times
• If unresponsive, and help is available, have the person call 911 and report back to you, if you are alone, (Difference 1) initiate CPR and perform 5 reps of 30 compressions with two rescue breaths in between, once done call 911
