Newborn Care in Cold Weather

By Dr. Zahoor Hussain Daraz

Are newborns more sensitive to cold than adults?

Yes, and it's not a small difference. A newborn has a lot more skin surface for their weight than you do, and their body hasn't learned to regulate temperature the way yours has after decades of practice. They lose heat fast.

Here's the check I give every parent: don't judge by the hands and feet. Cold hands are normal — blood is being kept for the core organs, not the fingers. What actually matters is the chest or the back of the neck. Slip two fingers under the clothing and feel there. If that's cold, your baby is cold. Pair that with pale skin, a bluish tinge around the lips, unusual fussiness, or a baby who's suddenly less interested in feeding, and it's time to warm them up and pay attention.

Are newborns immune to colds?

No — the opposite, actually. Newborns are born with some antibodies passed on from the mother during pregnancy, and breastfeeding adds more, but that's partial protection, not immunity. Their immune system hasn't met most common viruses yet, which is exactly why a mild cold in an older sibling or a visiting relative can knock a newborn harder. This is also why I tell parents to be cautious about a stream of visitors in the first few weeks — it's not about being unfriendly, it's that a newborn's defenses are still under construction.

Can a newborn catch a cold from their mother — and can I still care for my baby if I have one?

Yes, they can catch it, and yes, you can still care for them — this is the question that worries mothers most and the answer is almost always: keep going, just be careful. Wash your hands before you touch the baby, especially before feeding. A mask while you're holding or nursing them cuts down what you're breathing near their face. What you shouldn't do is isolate yourself from your baby out of guilt — breastfeeding while you have a cold is generally fine and actually passes on some antibodies.

Watch the baby, not just yourself. A cold in a newborn can look different from a cold in you.

How dangerous can cold weather actually get for a newborn?

Genuinely dangerous, which is why I don't like softening this. Newborns can develop hypothermia faster than older children, and it doesn't always look dramatic at first — a baby who's too cold often just gets quiet and sleepy rather than crying about it, which is exactly why parents miss it. Keep the room between 20–22°C. A cheap room thermometer is worth more than guessing by feel, because a room that feels comfortable to an adult moving around can be too cool for a baby lying still.

How do I know if my newborn is cold?

Skip the hands and feet test — they run cold on a perfectly warm baby, it's just circulation prioritizing the core. Feel the chest or the back of the neck instead, with two fingers slipped under the clothing. If that skin feels cool, your baby is cold, even if the room feels fine to you. Other signs to watch alongside that: skin that looks pale or slightly mottled, a baby who's fussier than usual or unusually quiet, and reduced interest in feeding. Warm them gradually — skin-to-skin contact under a blanket works faster and more evenly than piling on layers all at once.

Day to day — what does winter care actually look like?

Layering, not one heavy layer. A cotton onesie, a sleeper over it, and a swaddle or sleep sack on top works better than one thick blanket that can bunch up or get kicked off. In houses that rely on a bukhari or central heating, the air dries out fast — a humidifier in the baby's room helps more than people expect, especially for a newborn's nose and skin.

One thing I say in almost every winter consultation here: keep the kangri away from the baby, and don't use a hot water bottle directly against their skin either. Both are common in Kashmiri homes and both have caused burns I've had to treat. If you want a warm bed, warm it before the baby goes in — a hot water bottle wrapped in a thick towel, placed under the sheet and removed before you lay the baby down.

Bringing a newborn home from the hospital in winter

Dress them in the layers above before you leave, and bring a blanket for the car seat rather than a thick padded snowsuit — bulky suits stop the car seat straps from sitting properly against the body, which matters more in a crash than people realize. Have the house warm before you arrive, not warmed up after.

Can I take my newborn outside in winter?

For the first few weeks, I'd keep outings short and skip them on the coldest or windiest days. After that, short trips are fine as long as your baby is layered and their face isn't exposed to direct wind for long. What I actually tell parents to avoid isn't the cold air itself — it's the temperature swing. Going from a warm, heated room straight into freezing air and back again repeatedly in one outing is harder on a newborn than steady cold.

What should a newborn wear in winter?

Onesie, sleeper, sleep sack or swaddle, a soft hat, and socks or booties. Mittens if their nails are catching their face. What I'd skip: a coat or jacket indoors — it's one of the most common reasons I see babies brought in "too warm," sweaty, with a heat rash. Coats are for outside, and they come off the moment you're back in.

What should a newborn wear in summer?

Lighter layers, but don't strip them down to nothing — the same weak temperature regulation that makes newborns lose heat fast in winter also makes them overheat fast in summer. A single layer of breathable cotton is usually enough indoors; a light cap outdoors helps in direct sun. A good rule: dress your baby in roughly the same number of layers you're comfortable in, maybe one extra, not more. Skip synthetic fabrics that trap heat and sweat. If your baby's back or chest feels damp and hot rather than just warm, they're overdressed — take a layer off.

Should a newborn's milk be warmed, or is cold milk okay?

I generally recommend room-temperature or warmed milk, mainly because most babies simply take it better — a lot of newborns will refuse or fuss at milk straight from the fridge. It's not a safety issue so much as a comfort and feeding-efficiency one; a baby fighting cold milk tends to feed less and fuss more. If you're warming a bottle, stand it in warm water rather than using a microwave, which heats unevenly and can leave hot spots that won't feel hot to your wrist test but will scald your baby's mouth.

Cold and flu season — what should actually make you call the clinic

A stuffy nose and some sneezing in a newborn is common and usually not urgent — babies are new to breathing air full of dust and germs and it takes adjustment. What should get you calling immediately: bluish lips or face, breathing that looks like real effort (the chest pulling in with each breath), a fever in a baby under 3 months, unusual lethargy where they're hard to wake or keep awake, or refusing feeds. Don't wait these out.

If anything here doesn't fit your baby specifically, that's what consultations are for — come in and let's look at them properly rather than guessing over a screen.
