Skin-to-skin contact — sometimes called kangaroo care or koala care — is one of the most well-researched interventions in newborn care, and one of the simplest. It requires no equipment, no special skills, and no preparation. Just a bare chest and a baby.
Yet for something so straightforward, its effects are remarkably far-reaching — on breastfeeding establishment, milk supply, your baby's physiology, and the bond between you.
What is skin-to-skin contact?
Skin-to-skin contact means placing your newborn directly on your bare chest — tummy down, cheek turned to one side — with a blanket over their back for warmth if needed. The baby is undressed except for a nappy. Your body warmth, heartbeat, breathing rhythm, and scent all work together to regulate your baby's systems.
It can happen in the delivery room immediately after birth, in the NICU with premature babies, during the early weeks at home, or any time throughout your breastfeeding journey when you want to support supply or reconnect.
What does skin-to-skin do for breastfeeding?
It triggers the hormones that start milk production
Physical contact with your newborn — particularly skin-to-skin — stimulates the release of oxytocin and prolactin. Prolactin is the primary hormone responsible for milk production. Oxytocin triggers the let-down reflex (the release of milk during feeding). Both are strengthened by skin-to-skin contact, particularly in the early days when supply is being established.
It activates your baby's feeding instincts
Newborns placed skin-to-skin on their mother's chest after birth will, if left undisturbed, typically move toward the breast and self-attach within the first hour. This is known as the breast crawl, and it's a demonstration of the instinctive feeding behaviours that skin-to-skin activates. Studies consistently show that early skin-to-skin is associated with higher rates of breastfeeding initiation and longer breastfeeding duration.
It supports milk supply throughout your journey
The benefits don't end after the first hour or the first week. At any point in your breastfeeding journey, increased skin-to-skin contact can support supply — particularly useful if supply has dipped, during a difficult patch, or when transitioning back to work and wanting to maximise at-home feeds.
It improves latch
Babies who have regular skin-to-skin contact are often better at self-attaching and feeding effectively. The proximity and familiar scent of the breast means they're primed to feed, and the relaxed physical state that skin-to-skin induces makes efficient latch more likely.
What does skin-to-skin do for your baby?
The effects on your baby extend well beyond breastfeeding:
Temperature regulation
Newborns have limited ability to regulate their own body temperature. Your chest is a remarkably effective incubator — it warms a cold baby and cools a warm one, adjusting as needed. This is why skin-to-skin is standard care in NICUs for premature babies who can't maintain their own temperature.
Heart rate and breathing stabilisation
Newborns in skin-to-skin contact show more stable heart rates and more regular breathing patterns than those kept in a crib. Your breathing rhythm and heartbeat provide an external cue that helps your baby's own systems regulate.
Blood sugar stabilisation
Early skin-to-skin and breastfeeding help stabilise newborn blood glucose levels, reducing the risk of neonatal hypoglycaemia. This is particularly relevant in the first hours after birth.
Reduced stress
Cortisol (the primary stress hormone) is measurably lower in babies who have regular skin-to-skin contact. The physical closeness and familiar sounds of your heartbeat and voice are calming in a way that a crib cannot replicate.
Microbiome development
Your skin carries bacteria that help colonise your baby's microbiome — the community of microorganisms that plays a foundational role in immune development. Skin-to-skin contact is one of the ways this beneficial colonisation happens.
What does skin-to-skin do for you?
The hormonal effects of skin-to-skin contact aren't one-directional. Holding your baby skin-to-skin:
- Reduces maternal cortisol — the physical act of holding your baby is calming, and cortisol levels in mothers decrease during skin-to-skin contact
- Boosts oxytocin — the bonding hormone that also supports milk let-down
- May reduce risk of postnatal depression — multiple studies show an association between regular skin-to-skin contact and lower rates of postnatal depression, though the relationship is complex
- Supports bonding — particularly relevant for parents who had a difficult birth, a caesarean, or early separation from their baby
Partners can do skin-to-skin too
Skin-to-skin isn't limited to the birthing parent. Partner skin-to-skin provides the same temperature regulation and calming benefits for the baby. It also helps partners feel more connected and confident in the early days when breastfeeding can feel like an activity they're excluded from.
This is particularly useful when the feeding parent needs to rest — a partner can do skin-to-skin to settle a baby between feeds without disrupting supply or feeding cues.
When to do skin-to-skin
Immediately after birth
If it's safe for mother and baby, immediate skin-to-skin in the delivery room — before the baby is weighed, bathed, or dressed — is associated with the best outcomes for breastfeeding initiation. If immediate skin-to-skin isn't possible (due to caesarean, NICU admission, or other medical factors), it can be started as soon as mother and baby are stable.
During the first weeks at home
The newborn period is the most important window, but there's no deadline. Regular skin-to-skin throughout the early weeks continues to support supply, latch, and bonding.
When supply dips or feeding is difficult
Increasing skin-to-skin contact during a difficult patch — supply concerns, a latch regression, a baby who has become distracted or fussy at the breast — can help reset the feeding relationship and stimulate supply.
During cluster feeding
Skin-to-skin during cluster feeding sessions can make a long evening of intense feeding more comfortable and sustainable. See our guide to cluster feeding for more on managing these phases.
Practical tips for skin-to-skin at home
- Make it comfortable for you — use a nursing pillow for arm support, have water within reach, and sit in a position you can sustain for 20–30 minutes
- It doesn't have to be a dedicated activity — you can read, watch television, or rest while doing skin-to-skin
- Aim for at least 20–30 minutes — this is long enough for the hormonal effects to activate, though even shorter periods have benefits
- Keep baby safe — ensure your baby's airway is clear (cheek to one side, not face-down), don't fall asleep in a chair or sofa with a newborn on your chest, and follow safe sleep guidelines
Frequently asked questions
Does skin-to-skin help with milk supply?
Yes. Skin-to-skin stimulates prolactin and oxytocin, both of which are directly involved in milk production and let-down. It's particularly effective in the early days of establishing supply, and can help at any point when supply needs support.
How long should skin-to-skin sessions be?
There's no fixed minimum, but most research has been done on sessions of at least 30–60 minutes. Even shorter periods have benefit. Longer is generally better during the newborn phase.
Can I do skin-to-skin after a caesarean?
Yes — many hospitals now support immediate or early skin-to-skin in the operating theatre for uncomplicated caesareans. If this isn't possible during surgery, it can begin in recovery as soon as you're both stable. Talk to your midwife or obstetrician about their facility's approach.
Is skin-to-skin still beneficial after the newborn phase?
Yes, though the most well-documented effects are in the first weeks. Older babies still benefit from the closeness and it continues to support the breastfeeding relationship. There's no age at which it becomes unhelpful.
Can skin-to-skin help if I'm pumping rather than breastfeeding directly?
Yes. Skin-to-skin with your baby before and during pump sessions can improve let-down and output by stimulating oxytocin. Some mums find that looking at a photo or video of their baby achieves a similar effect if direct contact isn't possible during pumping.
