What should a baby wear under a sherpa jumpsuit?

Dress for where you are going

The jumpsuit is the part that comes off. Once you reach a warm house, a heated shop or a wedding hall, your baby will be in whatever is underneath, possibly for hours. So the question is really: what would they need indoors at the place you are visiting? Dress them for that, then add the sherpa for the journey.

That also keeps things simple when the outing changes. If you end up sitting in a cold courtyard for longer than planned, you can keep the jumpsuit on; if you walk into a room with a gas heater roaring, you take it off and they are still properly dressed.

The layers underneath also need to suit the car seat, because they are what your baby wears under the harness on the drive. Keep them thin enough for the straps to sit snugly.

A simple three-part formula

• Next to the skin: a bodysuit with poppers, short or long sleeved depending on how cold the day is.
• Middle: a two-piece knit set such as the Oatmeal Teddy Ribbed Top & Jogger Set, or a footed sleepsuit such as the Sky Blue Teddy & Stars Footed Sleepsuit for a younger baby.
• Outside: the sherpa jumpsuit, zipped up, hood up only while you are outdoors.
• Extras on bitter days: socks if the jumpsuit has open feet, a thin hat under the hood, and mittens.
• One base layer is enough on most days. A vest under a bodysuit under a knit set under sherpa is usually more than a baby needs outside the far north.

Three real days, three answers

• A midday drive across Lahore in January: sleepsuit underneath, sherpa on for the walk to and from the car, off once buckled in with a blanket over the harness instead.
• An evening pram walk in Islamabad: bodysuit, knit set, sherpa jumpsuit, thin hat, and a blanket tucked in at chest height.
• A December evening at a Karachi relative’s house: bodysuit and knit set are usually enough. The sherpa can stay at home unless a cold wind is blowing off the sea.

What to leave out underneath

• Chunky cable sweaters. Sherpa plus a thick sweater is a lot of bulk, sleeves get tight at the elbow and babies overheat quickly once you are indoors. Save the heavy knit for days without the jumpsuit.
• Hoodies. Two hoods bunch up behind the neck and push the head forward in the pram.
• Stiff trousers or anything with a big belt, buckle or bow at the back, which will press into your baby when they lie down.
• Clothes with long cords or ties that could loop around fingers or catch on pram parts.

Try the fit with the layers on

Before a cold snap, put the jumpsuit on over the layers you will actually use. The zip should close without straining, your baby should be able to bend their arms and knees, and the hood should sit on their head, not over their eyes. If it is tight with a knit set underneath, a sleepsuit may be the better middle layer, or you may need the next size; our size guide lists height ranges for each. Our Cream Puppy Sherpa Hooded Jumpsuit comes in 0–3M to 18–24M.

Once you are out, feel the back of your baby’s neck from time to time. If it is sweaty, unzip or take a layer off. Our guide to dressing a baby for winter in Pakistan goes through the signs your baby is too hot.
