Saul Perez, 20, holds his newborn child as he participates in the "Kangaroo Mother" program at the National Maternity Hospital in San Salvador May 11, 2011. The "Kangaroo Mother" program is a technique used for the care of babies who were born premature and underweight. Doctors say the body-to-body contact helps to increase the baby's weight and fosters a better relationship between the newborn and his mother, for better growth development. In the National Maternity Hospital of El Salvador, 13,335 women gave birth in 2010 and 18% of children born prematurely, according to data from the Maternity Hospital of El Salvador. [Photo/Agencies]
