Studies show that newborns are soothed by the sound of a human heartbeat, which they grew accustomed to hearing in the womb. Let your baby experience this comforting sound often by lying with him on your chest, skin to skin. Or sit in a chair and let his head rest against the left side of your chest, which psychologist Lee Salk and others have noted is the side on which most mothers intuitively hold their babies anyway. Notice how the sound and feel of your beating heart can calm your newborn.
