Answer:
Place the heel of one hand on the breastbone -- just below the nipples. Make sure your heel is not at the very end of the breastbone. You may need to use both hands depending on your size and the size of the child.
Keep your other hand on the child's forehead, keeping the head tilted back.
Press down on the child's chest so that it compresses about one third to one half the depth of the chest.
Give 30 chest compressions. Each time, let the chest rise completely. These compressions should be fast and hard with no pausing. Count the 30 compressions quickly: "1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30, off''.
