A Pilot Randomized Controlled Trial of the Effects of Daily Skin-to-skin Contact (PRCTS2S)

Skin-to-skin contact will be performed for two hours daily for three consecutive days in the first week of life, usually in the afternoon. This time interval will allow all pre-intervention sample collection to begin 1 hour after the infant's feeding schedule in the afternoon. After pre-intervention measures of axillary temperature, heart rate, respiratory rate, and oxygen saturation by pulse oximetry (SPO2) are obtained; cotton balls placed in the diaper for urine collection will be removed and stored in an appropriate container. Salivary oxytocin and cortisol will be collected per protocol below. Mothers will be requested to sit in reclining chairs with a front opened blouse or hospital gown. Infants will be removed from the incubator and placed naked except for a diaper and hat directly onto the skin between the mother's breasts and covered with a blanket. All infants will be monitored. After the two hours of SSC is completed, the infant will be returned to the incubator.
