What Exactly are the Benefits of Kangaroo Care and how do they Work?

Many medical studies have been performed to establish exactly what the benefits of Kangaroo Care are for both mother and baby (preterm and full term). These studies have consistently proven immense benefits and demonstrated exactly what those benefits are and how they happen - you can find links to many of these studies below and we can summarise their findings as follows:


Improved Neurodevelopmental Outcomes - Infants cared for with Kangaroo Care have better mental development.

"Infants who receive Kangaroo Care score higher on the Mental Development Index and Psychomotor Development Index of the Bayley Scales of Infant Development both at 6 months and 12 Months when compared with infants who received conventional Care." (1) 

"Skin to Skin Contact accelerates brain maturation" (2) 

"Kangaroo Care positively influenced brain networks and synaptic efficacy up to adolescence." (3)


Improved Physical Developmental Outcomes - Infants cared for with Kangaroo Care grow more quickly and establish physiological self regulation more quickly. 

"Kangaroo Care infants gained more weight per day (typical MD 3.7 g, 95% CI 1.9 to 5.6; 10 trials, 1072 infants), and length (typical MD 0.29 cm, 95% CI 0.27 to 0.31; two trials, 251 infants) and head circumference (typical MD 0.18 cm, 95% CI 0.09 to 0.27; three trials, 369 infants) per week than controls [non-KMC*]" (4) 

"...evidence suggests that the kangaroo position has a positive influence on the motor activity in newborns…" (5) 

"Kangaroo Care increases sleep time, including time spent in quiet sleep. At term, preterm infants who have received Kangaroo Care during their stay in the NICU demonstrate longer periods of quiet sleep and alert wakefulness, shorter periods of active sleep, and more organized sleep-wake cyclicity when compared with infants who did not, suggesting more rapid improvement in state organisation. These infants are also more alert and responsive, and less irritable and fussy." (6)


Easier Establishment of Breastfeeding and Longer Duration of Breastfeeding - Mothers who practise Kangaroo Care find breastfeeding more easy and infants cared for with Kangaroo Care are 8 times more likely to breastfeed within 60 minutes post birth and breastfeed for longer. 

"Babies breastfed more successfully during Skin to Skin Contact immediately postbirth than if they were held swaddled in blankets, probably because of the extra tactile, odor, and thermal cues provided by Skin to Skin Contact" (4) 

"Kangaroo Care is associated with a longer duration of breastfeeding, higher volumes of milk expressed, higher exclusive breastfeeding rates…" (6)

"Mothers of Kangaroo Care infants were more likely to be breastfeeding at discharge ...Compared with conventional care, Kangaroo Care was associated with an increase in the likelihood of exclusive breastfeeding at discharge" (4) 

"Infants who are allowed uninterrupted Skin to Skin Contact immediately after birth and who self-attach to the mother's nipple may continue to nurse more effectively. Effective nursing increases milk production and infant weight gain" (4) 


Improved Psychological and Emotional Wellbeing for Mother - Kangaroo Care causes the release of the (relaxation) hormone Oxytocin and a reduction in the (stress) hormone cortisol in mothers.  

"Skin to Skin Contact through sensory stimuli such as touch, warmth, and odor is a powerful stimulant, which among other effects releases maternal oxytocin… Skin to Skin Contact also lowers maternal stress levels...Oxytocin antagonizes the flight-fight effect, decreasing maternal anxiety and increasing calmness and social responsiveness...Skin to Skin Contact outcomes for mothers suggest improved bonding/attachment... other outcomes are increased sense of mastery and self-enhancement, resulting in increased confidence." (4)

"Mothers who have had the opportunity to provide Kangaroo Care for their infants describe feelings of being needed, increased confidence in knowing their infants and a sense of their role as a mother." (6)

"...analysis showed the positive effects of Kangaroo Care on the rate of maternal mental health scores. There were statistically significant differences between the mean scores of the experimental group and control subjects." (7)


Enhanced Bonding and Attachment - Mothers and fathers who practise Kangaroo Care feel a stronger attachment and bond with their infants and are better able to interpret infant cues.

"Near the time of discharge home, mothers were observed to look at and touch their infant more frequently, show more positive affect and be more adaptive to their infant’s signals than did mothers who had not provided Kangaroo Care. When followed after discharge, these same mothers, as well as fathers, provided a better home environment and were more sensitive to their infant." (8)

"...maintenance of the maternal milieu following birth is required to elicit innate behaviors from the neonate [newborn*] and the mother that lead to successful breastfeeding, and thus survival. Separation from this milieu results in immediate distress cries (Alberts 1994) and "protest-despair" behavior. Human infants placed in a cot cry 10 times more than Skin to Skin Care infants." (6)
