Kangaroo care or kangaroo mother care (KMC) is the name given for carrying a newborn baby in continuous skin-to-skin contact, snuggled against a parent’s chest and ideally fed exclusively on breast milk. When carried in skin-to-skin contact with his mother, the newborn baby feels safe and calm and instinctively searches for the breast to latch and breastfeed. Not only is kangaroo care very helpful to breastfeeding success, it has many other advantages for the newborn by reducing stress and promoting healthy brain development—factors particularly important for the vulnerable premature baby. Kangaroo care is recognised as the best start in life for premature babies by the World Health Organisation 1.
Why kangaroo care?
In the uterus a baby is constantly nourished and firmly held, sounds are muffled, lights are dimmed, his fragile skin is protected by fluid and his lungs and brain can steadily prepare for independent life. By contrast, it is very stressful for a premature baby to find himself thrown into a world of bright lights, harsh sounds and separation from mother. In the neonatal care unit (NICU) babies may twitch, change colour, have an uneven heart rate and breathing, and may be tense, fussy, get very tired and they are aware of being separated from their mother. Although technology can assist the little prem baby who needs help with breathing, temperature regulation, loss of fluids and other medical care; by holding your baby close to you in kangaroo care, the conditions closest to those back in the uterus can be recreated. This helps premature babies stabilise their heart rate, breathing and temperature, it reduces their stress levels which helps them establish breastfeeding sooner and grow faster.
When can kangaroo care start?
The sooner a baby can have kangaroo care, once they have received any urgent medical interventions, the sooner it helps their little bodies adapt to life outside the womb. Kangaroo mother care can stabilise babies faster than an incubator and provides the stimulation to their senses needed for healthy brain development such as feeling safe and warm, smelling and looking at their mother, tasting breast milk, or hearing their mother’s heart beat. Premature babies can begin to breastfeed from 28 weeks gestation but kangaroo care can get started before this, even while your baby still needs oxygen or intravenous fluids, and will help to get breastfeeding established earlier. See Breastfeeding a Premature Baby for more information about breastfeeding.
Many places will only allow SSC [skin-to-skin contact] once your prem is “stable”, a particular weight and off all monitors and machines. This is a a problem as babies quickly stabilise in skin-to-skin contact but they can take days to stabilise in an incubator.
Advantages of kangaroo care
#1 More stable
In kangaroo care the feelings of safety and security provided by the mother’s body allow the baby’s body functions to regulate. In skin-to-skin care the baby’s heart rate, blood pressure and temperature stabilise, oxygen saturation is more stable, breathing is better with less episodes of apnoea, and baby experiences better quality sleep than in incubator care. And so a premature baby is less stressed and better able to digest food to grow 2 3 4.
A mother’s chest regulates a baby’s body temperature more consistently than an incubator. Breasts can warm a baby if he is too cold and cool him down if he is too warm (Bergman, 2010).
#2 More sleep
Sleep is very important to the premature baby for their brain development, emotional health and memory. The premature baby sleeps soundly on his mother but he cannot sleep properly in an incubator (Hold Your Prem, Bergman, 2010). Holly Richardson explains:
During kangaroo care, a premature baby’s overall growth rate increases. This is in part due to the baby’s ability to sleep, thus conserving energy and putting caloric expenditure toward growth. According to Dr. Ludington, during the last six weeks of pregnancy, babies sleep twenty to twenty-two hours per day. In a typical NICU, however, they spend less than two hours total in deep, quiet sleep. Most of that comes in ten or twenty second snatches. With kangaroo care, the infant typically snuggles into the breast and is deeply asleep within just a few minutes. These babies gain weight faster than their non-kangarooed counterparts, and it is interesting to note that they usually do not lose any of their birthweight.
#3 Less crying, less stress, more attachment
Crying is extremely stressful for a premature baby and uses up precious calories. Crying increases a baby’s heart rate and blood pressure, this can open a valve between the two sections of the baby’s heart, so that deoxygenated blood can be sent to the brain instead of the lungs. By raising the blood pressure, crying can also cause a brain bleed, a common problem in premature babies. By caring for a baby in kangaroo care, there is less crying, and the baby is better able to cope with any stress that he does encounter 5.
For prematures they need mother EVEN more to stabilise. Instead they are taken to ICU, given sugar, put in incubator with bright lights, loud sounds, with strange smells of disinfectant etc. They cry and we have MADE THEM WORSE by separating them from mum.
Bonding and attachment
The increased bonding in kangaroo care helps long term emotional health 6.
#4 Better digestion, more growth
In kangaroo care the premature baby has less of the stress hormones somatostatin and cortisol. Presence of somatostatin slows down the gut and so the baby’s growth rate. Cortisol increases blood pressure which can contribute to the brain bleeds common in premature babies (Bergman, 2010). In addition, skin-to-skin contact may promote the release of digestive hormones 7.
In skin-to-skin contact, the baby is in a relaxed mode so all her hormones prepare her gut to absorb food maximally. SSC babies can grow at 30g per day which is twice the rate of an incubator baby. Skin-to-skin care will mean less time in hospital.
See Breastfeeding a Premature Baby for more references on weight gain.
#5 Optimal brain development
Brain growth is as important as physical growth for the premature baby. What a baby feels, senses and digests is vital to his healthy brain development. Being cared for in a brightly lit baby care unit and separated from his mother in an incubator is very different to being carried in a uterus with all his needs met naturally. Kangaroo care allows the developing baby to feel, touch, hear, smell his mother, taste her breast milk and feel safe. These are all sensations that “fire and wire” the brain correctly which ultimately determine a baby’s emotional development. The close presence and touch of parents are therefore vital for a premature baby’s brain to develop normally. Breast milk also contains 200 or more “non protein nitrogens” to correctly build the human brain and gut and provide immunity. Cows’ milk, in contrast has only 2% of these non protein nitrogens (Bergman, 2010). See Breastfeeding a Premature Baby and Human Milk Fortifiers more information about nutrition for a premature baby.
#6 Helps breastfeeding and health
Carrying your baby in kangaroo care has many advantages to breastfeeding; breastfeeding usually starts more easily 8, more breast milk is produced, feeds are more frequent, there is better digestion and faster weight gain. Breastfeeding also supports a significant decrease in diseases such as pneumonia, septicaemia and necrotising enterocolitis 9 10. See Breastfeeding a Premature Baby for further information.
#7 Advantages for parents
Kangaroo care can help parents bond and interact with their baby, feel empowered and more confident because they are able to help with their baby’s care. Skin-to-skin contact releases more oxytocin which helps with feeling calm and with mother’s milk supply. Mothers can feel less depressed, less stressed and better able to cope with having a premature baby when they care for their baby by this method 11 12.
#8 Financial savings
Kangaroo care can create substantial financial savings to families and health care facilities thanks to less reliance on technology, parents carrying out much of their baby’s care and shorter hospital stays 13.
How to do kangaroo care
A baby wearing only a nappy and held under mothers clothes next to her breasts allows full skin-to-skin contact for kangaroo care. The more skin-to-skin care your baby can have the better. Jill Bergman advocates firm holding or “containment” as feather-light touch or stroking can irritate a baby’s sensitive skin. Jill and Nils Bergman explain how to do kangaroo care:
Your baby only needs a tiny nappy and cap.
Wash your hands well every time you come to your baby. Use plain soap without any perfumes.
Mum, take off your bra but keep your shirt on, it is easiest if you have one that buttons down the front. Put your baby inside, against your skin.
Sit in a chair with cushions so you can lean back a bit and be comfortable. It is best for your baby if you are half lying, half sitting. The angle of 30-40 degrees helps her breathing. Place your baby on your chest facing you with her legs curled up in the foetal position. This is best for her hips. Put her tiny hands near her face for self-soothing. She has been doing that for months in the womb already. You can hold your hands underneath and behind her.
Cover her and yourself. Your body will automatically warm up if your baby is cold or will cool down if your baby is hot.
Your baby can be held in skin-to-skin contact as long as you want, for part or all 24 hours per day. It is important for your baby to go through a full sleep-wake cycle which is usually about 60 minutes as a minimum to get the full benefits of SSC, and to get her biological systems stabilised.
Special carriers are available so you can walk around with your baby in kangaroo mother care e.g. the KangaCarrier shirt.
Kangaroo mother care is an important part of the care of a premature baby whatever the medical setting. Not only does it help stabilise a baby’s body systems and promote breastfeeding, it has important benefits for a baby’s brain development and emotional health.
