Testing Kangaroo Mother Care for Normal Birthweight Newborns

Prolonged kangaroo mother care during the first 72 hours of life is currently under clinical evaluation for normal birthweight newborns, according to a trial protocol published in the British Medical Journal Open. While skin-to-skin contact is well established for small and preterm infants, researchers are testing whether extending the practice to healthy full-term babies weighing at least 2,500 grams can improve early weight changes and breastfeeding outcomes.

Trial Design across Three Uttar Pradesh Centers

The study involves a multicenter, pragmatic, individually randomized, controlled, open-label superiority trial. Investigators have designed the research to recruit 516 healthy singleton newborns and their mothers following uncomplicated vaginal deliveries at three public health facilities in and around Lucknow, Uttar Pradesh, India. Mother-infant dyads are randomized on a 1:1 basis. Both groups receive a common minimum package of essential newborn care, which includes breastfeeding initiation through uninterrupted skin-to-skin contact during the first hour, routine clinical care, counseling, vaccinations, and advice on hygiene, thermal care, breastfeeding, and danger sign recognition.

In the intervention arm, mothers receive specialized counseling from a trained team to provide at least eight hours of skin-to-skin contact daily during the first three days after birth. The intervention combines this prolonged contact with exclusive breastfeeding while in the kangaroo mother care position. Both mother and infant remain bare-chested, with the baby wearing a cap and socks while a blanket covers the infant’s back and the mother’s chest. Mothers may sit semi-reclined or practice ambulatory care using a binder, and family members are permitted to support the contact sessions to extend their duration.

Thermoregulation and Metabolic Stabilization Needs

At birth, a newborn transitions to independent life through adaptations across multiple organ systems. While cardiorespiratory adaptation occurs rapidly within the first two to six hours, metabolic and thermoregulatory stabilization continues over the subsequent 24 to 72 hours. Uninterrupted skin-to-skin contact during the first hour supports this transition and aids in initiating breastfeeding. Breastfeeding subsequently contributes to thermoregulation, metabolic stability, immune protection, and bonding.

For preterm and low-birthweight infants, prolonged kangaroo mother care improves survival rates by 32 percent, alongside enhancing thermoregulation, metabolic stability, breastfeeding, neurodevelopment, and maternal mental health. Investigators note that evidence for healthy newborns weighing at least 2,500 grams remains limited, though some data suggest prolonged contact may help prevent hypothermia at discharge and manage hyperbilirubinemia. Furthermore, infants positioned in this manner are more likely to self-latch using innate reflexes rather than learned feeding behaviors, which could increase milk intake.

Follow-Up and Feeding Protocols

Mothers participating in the intervention are encouraged to continue skin-to-skin practices according to their comfort level throughout the first 28 days of life. Breastfeeding is conducted on demand and led by the newborn, with mothers receiving instruction on positioning and supporting the breast to allow self-attachment without interference. A trained support team provides practical assistance and records exposure times. For mothers discharged before completing 72 hours in the facility, home continuation is encouraged alongside telephone follow-ups to assess ongoing exposure.
