Heart massage

Undress your child to the belly button.
To locate his heart, place a finger above the sternum. Place the palm of a hand here. Sit well above, the arm perpendicular to his chest. With the arm extended, squeeze the sternum with one hand. Release everything and count to 10 while observing your child. Repeat.
One cycle is composed of 10 heart and 2 mouth-to-mouth massages. You can go up to 10 cycles per minute.
