Your mother-in-law says a daily malish will make the baby gol-matol. Your paediatrician shrugged when you asked. And you're sitting there at 10pm with a bottle of oil, wondering whether this is tradition or something that actually does something.
Yes, there is real research here. Most of it is positive. Studies on preterm and low-birth-weight babies consistently show faster weight gain in massaged infants compared to those who weren't massaged, with earlier hospital discharge. For healthy, full-term babies the evidence is thinner and the weight effect is smaller. But malish does other things — better sleep, calmer babies, a stronger skin barrier — that make it worth doing regardless of the scale.
At a glance
- The strongest evidence is in preterm and low-birth-weight babies, where massage is linked to faster weight gain and earlier discharge.
- For healthy full-term babies, the weight effect is small and inconsistent — don't massage only for weight.
- The likely mechanism is vagal stimulation and better feed absorption, not the oil "feeding" the skin.
- Massage does not replace feeding. A baby who isn't gaining needs a paediatrician, not more oil.
- Firm, slow, consistent strokes beat light tickling — pressure matters more than the oil brand.
- 15 minutes, twice a day, is the pattern most studies used.
What does the research actually show about malish and weight gain?
The bulk of the good work comes from neonatal units — India, Iran, the US, Taiwan. Preterm babies who received structured massage (usually moderate-pressure stroking plus gentle limb movement, 15 minutes, two or three times a day) gained weight faster than control babies on identical feeds. Same milk. Different weight gain. So it isn't that massaged babies eat more.
Reviews pooling these trials have landed on the same direction repeatedly. Indian NICUs took it seriously enough that structured infant massage is part of care in many units now, particularly alongside kangaroo mother care. If you've sat outside an SNCU in a district hospital and watched a nurse teach a mother the strokes, you've seen this evidence being used.
The full-term picture is muddier, and I'd rather say so. Healthy babies at home are already gaining well, feeding on demand, being held constantly. There's less room for improvement, and the studies show it — some find a modest effect, some find none. If your six-week-old is on her growth curve, malish is not going to move her to a higher percentile.
Why would rubbing a baby change their weight?
The explanation researchers keep coming back to is the vagus nerve. Moderate-pressure touch stimulates it, which nudges the release of gut hormones — insulin and gastrin among them — that improve how efficiently a baby absorbs and stores what they've already been fed. There's a stress-hormone angle too. Calmer babies burn fewer calories on crying and restlessness, and sleep more deeply.
The oil plays no part in any of that. Nothing in the mechanism depends on which oil you use, or whether oil is used at all. Oil reduces friction so you can stroke firmly without dragging thin skin — that's its job. In India it also does real barrier work, which matters when winter air is dry and the tap runs hard water. But that's a skin benefit, not a weight one.
What the evidence supports — and what it doesn't
| Claim you'll hear | What the evidence actually says |
|---|---|
| "Malish makes preterm babies gain faster" | Reasonably supported. Consistent across multiple neonatal trials. |
| "Malish makes a healthy baby chubby" | Weak. Small or no effect in full-term babies already growing well. |
| "Massage helps babies sleep better" | Supported, and the effect parents notice most. |
| "The oil gets absorbed and nourishes the baby" | Not how it works. Skin absorbs very little; oil's role is barrier and glide. |
| "Massage can fix poor weight gain" | No. Poor gain is a feeding or medical issue — see a paediatrician. |
| "Harder strokes = faster growth" | No. Moderate pressure, not force. A baby should stay relaxed, not brace. |
A step-by-step malish routine you can start tonight
This is the order I settled on after fumbling through the first few weeks with my own, and it's what I send friends when they message at midnight. About 15 minutes, once you stop second-guessing yourself. Do it before the evening bath, so the oil comes off in the wash and you finish with moisturiser on clean skin.
- Pick the window. Roughly 45 minutes after a feed, when baby is awake and calm — not screaming-hungry, not milk-drunk. Late afternoon or early evening works best for the sleep knock-on.
- Warm the room, not the baby. 26-28°C, fan and AC off, doors shut. In a Nagpur summer that means waiting till the sun is off the balcony; in a Delhi winter, midday, near the window, before the smog haze sets in.
- Warm the oil in your palms. About a teaspoon at a time. Rub your hands together for five seconds. Never heat oil directly.
- Patch test first, if it's a new oil. A coin-sized dab on the inner forearm, wait 24 hours, check for redness.
- Legs first. Long strokes from thigh to ankle, one hand after the other, like gently milking. 6-8 strokes per leg. Legs are the least invasive place to start, so baby settles.
- Feet and toes. Thumb circles on the sole, a light squeeze down each toe.
- Arms, same pattern. Shoulder to wrist, 6-8 strokes each. Open the little fist and stroke the palm.
- Tummy, clockwise only. Flat fingers, gentle clockwise circles around the navel — that's the direction the bowel runs. Skip entirely if the cord stump hasn't healed.
- Chest. Both hands from the centre outward, like smoothing a page. No pressure over the breastbone.
- Back. Turn baby onto her tummy across your legs. Long strokes from neck to bottom. Most babies love this one.
- Watch the pressure. Enough that you see the skin move under your hand — not enough to see it whiten. If baby stiffens or turns away, ease off.
- Stop when baby says stop. Arching, crying, turning the head away — end the session. A 6-minute massage a baby enjoys beats a 15-minute one she endures.
- Bath, then moisturise within three minutes. Pat dry, don't rub, and seal damp skin while it's still slightly wet.
Which oil, and does it matter for weight?
For weight gain, no. For skin, yes. Walk into most Indian homes and you'll find one of three bottles: coconut, sesame or mustard. Coconut is the safest all-rounder for most babies and has decent barrier data behind it. Sesame is the classic Ayurvedic choice for winter and for cooler-natured babies — the one your nani reaches for in December. Mustard I'd avoid on newborns. It's a known irritant on thin skin, and that warming sensation parents like is exactly the problem. We've written about the differences in more detail in the Janma Journal if you want the long version.
Two rules whichever you pick. Unrefined and unscented. And stored somewhere it won't go rancid — not the shelf above the stove, which is where half of us keep it. Rancid oil smells sharp and can irritate skin, so sniff the bottle before every malish.
What to expect, honestly
Three weeks of doing it daily before you judge anything. What parents tell me about first isn't the scale — it's that the evening got easier. Baby settles faster. Wakes less between 10pm and 2am. The fussy hour softens. Weight, if it moves at all in a healthy full-term baby, moves quietly over months, and you won't be able to separate it from normal growth.
I know that's not the answer the malish-makes-them-fat crowd wants. But malish earns its place in your day on calm, sleep, skin and the sheer amount of skin-to-skin contact it builds in. The weight-gain evidence is a genuine bonus, strongest exactly where babies need it most.
After the massage: the skin part
Oil during malish, moisturiser after the bath. Different jobs. Oil lets your hands glide; a balm or lotion holds water in. If your baby's skin is dry, eczema-prone, or going through a north Indian winter, that post-bath step is the one that does the most to support her skin's natural barrier and comfort dry, sensitive skin. Fragrance-free. Thick enough to leave a slight sheen. Safe to use head to toe, every day.
When to see a doctor
Book a paediatrician appointment if your baby: hasn't regained birth weight by two weeks; is crossing downward across growth-chart centiles; has fewer than six wet nappies a day; feeds listlessly or falls asleep within minutes at every feed; or has a rash, redness or bumps that appear after starting a new oil and don't settle in 48 hours. Poor weight gain always deserves a real assessment — thyroid issues, reflux, tongue-tie, and feeding-position problems are all common and all treatable by a doctor, and none of them respond to massage.
If you'd like a post-bath moisturiser that's gentle enough for daily malish-and-bath routines on newborn skin, our Hydra Healing Moisturizing Balm was made for exactly that.
In summary
- Massage is linked to faster weight gain mainly in preterm and low-birth-weight babies, not healthy full-term ones.
- Moderate, firm pressure is the active ingredient — light tickling strokes showed little benefit in trials.
- Aim for 15 minutes before the evening bath, about 45 minutes after a feed, in a warm draught-free room.
- Skip the tummy until the cord stump has healed, and patch test any new oil 24 hours before use.
- See a paediatrician for any baby not gaining weight — massage supports growth, it never treats a feeding or medical problem.
Frequently asked questions
Does baby massage really increase weight?
In preterm and low-birth-weight babies, yes — multiple trials show faster weight gain with structured massage on identical feeds, plus earlier hospital discharge. In healthy full-term babies the effect is small and inconsistent. Massage is worth doing for sleep, calm and skin, but it won't push a well-growing baby to a higher percentile, and it never replaces addressing a feeding problem.
How many times a day should I massage my baby for weight gain?
Most research protocols used 15-minute sessions, two to three times a day. At home, once daily before the evening bath is realistic and enough for a healthy baby. Consistency matters more than frequency — three weeks of one daily massage beats a sporadic three-a-day week. Stop any session early if your baby arches, cries or turns away.
Which oil is best for baby massage to gain weight?
No oil has been shown to increase weight — the pressure of the strokes is what the research links to gain, not the oil. Choose based on skin instead: coconut is the safest all-rounder, sesame suits cooler weather and Ayurvedic practice, and mustard is best avoided on newborns because it can irritate thin skin. Always patch test a new oil.
Can massage help a baby who isn't gaining weight at all?
No, and treating it as the fix delays real help. Poor weight gain usually points to a feeding, latch, reflux, tongue-tie or medical issue that needs a paediatrician's assessment. Massage can be part of care alongside that, especially for preterm babies in hospital, but it is a support, never a treatment. Get the weight check done first.
Should I massage my baby before or after a bath?
Before. Massage with oil, then bathe so the excess oil comes off, then moisturise damp skin within about three minutes. Doing it the other way leaves an oily film that traps sweat and dust — a real problem in Indian humidity. Wait roughly 45 minutes after a feed before starting so your baby isn't full or hungry.
At what age can I start malish for a newborn?
Once the umbilical cord stump has fallen off and healed, usually around two weeks, you can massage the whole body — and skip the tummy entirely until then. Before that, gentle limb and back strokes are fine. Start with short 5-7 minute sessions and build up as your baby shows she enjoys it.
