Kangaroo Care: Why Does It Work? • Midwifery Today

As researchers studied brain wave patterns of infants in kangaroo care, they found two significant things. First, there was a doubling of alpha waves—the brain wave pattern associated with contentment and bliss. Second, they found that “delta brushes” were occurring. Delta brushes happen only when new synapses are being formed.
