How to Dress Baby for Winter Sleeping

Newborn Sleep Infant Sleep Product Information

Winter. The months when we hibernate indoors and share plenty of cuddles with our minis. It's about this time of year; that we get many questions about how to keep baby warm in winter at night, and rightly so, it's confusing. You don't want to underdress or overdress them. If just that sentence has you spinning, we got you.

Ideal room temperature for a baby to sleep

Let's start at the very beginning; your fresh newborn babe will most likely be in the same bedroom sleeping soundly (fingers crossed) right next to you. Or you have a wee baby sleeping in a crib in their own nursery. The ideal temperature for a nursery/bedroom while sleeping is 65°F - 69°F degrees, regardless of the season. We know that's not achievable for everyone, so our TOG rated range of newborn sleepwear ensures your baby is dressed appropriately for varying temperatures.


So, you have your room temperature sorted, now what?

You guessed it: what is a TOG? If you're new to this and wondering what the heck a TOG is, let alone getting your head around swaddling, we have your back.

A TOG stands for Thermal Overall Grade and is a unit of measurement for insulation and warmth of sleepwear and bedding. Put simply, the lower the TOG rating, the lighter the fabric. The higher the rating, the more padded and insulated it is.

With TOG-rated sleepwear, you do not need additional blankets in your child's sleep space. TOG rated fabrics are an essential tool that helps take the guesswork out of choosing your baby's right winter sleeping garment.

All ergoPouch sleepwear is TOG-rated and made from breathable, natural fibers such as soft organic cotton with 5% elastane, which allows for stretch in all directions across the chest. As your baby cannot regulate their temperature like adults can, the layers they wear to sleep are integral to ensuring they are at just the right temperature.

What TOG is right for winter?

For winter, we suggest dressing your baby in a Swaddle or Sleeping Sack with a 1.0 TOG or 2.5 TOG rating.

  • 1.0 TOG = suitable for a room temperature of 70 degrees Fº – 75 degrees Fº
  • 2.5 TOG = suitable for a room temperature of 63 degrees Fº – 73 degrees Fº

Now, let’s get to it: how to dress baby for sleep in winter!

Start with a 2.5 TOG Cocoon Swaddle Sack (Ideal for room temps between 63Fº -73Fº). If you have the heating on and your room is warmer in winter, opt for the 1.0 TOG (best for 70Fº -75Fº).

Ok, let's quickly run through Swaddling.

We swaddle our babies to avoid the sudden flailing of their arms and head that swiftly snaps them awake, undoing all that hard work it took to get them to sleep. That flailing movement is known as the Moro, or startle reflex. It is a jerk in their bodies that can occur every 20 minutes in some babies. It is entirely normal and begins in the first trimester in utero. A loud noise, a sudden bright light, movement or even a parent laughing can trigger the reflex.

Swaddling calms this jerking movement while keeping your mini comfortable and content. You can read more about swaddling. Your baby should be swaddled with their arms in for sleeping until they're rolling; learn about transitioning to arms-out sleeping.

Our Cocoon Swaddle Sack is a zip-up, no-fuss swaddle in stretchy organic cotton. It's hip-friendly, diaper-change friendly, and it transforms into a sleeping sack. It is designed to be both easy to use and difficult to escape from. A Cocoon Swaddle Sack removes the need for a blanket. Made in sizing 0000, 0-3m, 3-6m and 6-12months. Excellent for newborns either swaddled or arms out once rolling (see above blog for more info).

We know babies and children sleep better in natural fibers for the simple reason that they improve breathability and keep your little one's body at an even temperature, resulting in safe and content sleep for your mini.

2. Layer up for winter

Additional layers are an essential item for chilly nights and days, for that matter. Wondering how to layer baby clothes for winter? As a baby sleeps around 16 hours a day, you'll find you don't need to dress them in their day clothes vs nightclothes – a comfortable Long Sleeve Romper that is easily put on and removed is all you need. Your baby would wear their Romper underneath their Swaddle. Our sweet little Rompers are perfect for mixing and matching and TOG rated to boot. Each Romper is made from a beautifully soft, organic cotton fabric, making them breathable and comfortable.

When the colder winter months come around, it's sufficient to put your baby in a Long Sleeve 1.0 TOG or 0.2 TOG Long Sleeve Romper and place a 2.5 TOG Cocoon Swaddle Sack or 1.0 TOG Cocoon Swaddle Sack on top (room temp dependant). This will ensure your baby comfortable and won't overheat. And remember, when you use our Rompers and Cocoon Swaddle Sacks, you don't need to use any blankets.

Our new Baby Tuck Sheet is a TOG-rated, safe alternative to blankets suitable from birth. Designed to use over the top of a swaddle or sleeping bag, the Baby Tuck Sheet is a firm-fitting mattress sleeve that provides added security and comfort for a newborn during sleep. Each side of the Baby Tuck Sheet is TOG-rated; simply flip the sheet over to adjust the warmth and follow our Bedding Temperature guide (included) for help layering.

And that's it, our uncomplicated guide for how to dress your baby for winter and keep them warm at night. Fun fact, you will revive a FREE Room Thermometer with every Cocoon Swaddle Bag. This little beauty measures the temperature of your babe's room and recommends the right TOG and Layers. Did we mention it's free? And oh-so-helpful for sleep-deprived brains.

It's imperative to dress your child correctly to accommodate their room temperature while they're sleeping, as their little bodies are not as great at regulating temperature as our adult ones. Following our handy What to Wear Guide will take the guesswork out for you.


Mama to Mama (and Dad) Tips

  • To check your baby's temperature, just put your hand on their chest, tummy or back. This is the best way to feel if they are too hot or too cold, rather than feeling their hands or feet. Often your baby's feet or hands will feel cooler than their core temperature;
  • A baby who's too warm may have damp hair or be sweaty, flushed and have a fast pulse. In this case, remove a layer of clothing, and you can even try moving your baby to another room that's a bit cooler;
  • A baby who's too cold may not want to feed, may become lethargic and difficult to wake. There are warnings that a baby being too hot or too cold can increase the risk of SIDS. It's imperative to dress your baby correctly to accommodate their room temperature while they're sleeping;
  • Often your baby's feet or hands will feel cooler than their core temperature, which is normal! As a baby is developing their circulatory system, their body gives their vital organs priority when it comes to blood. As babies and children use their extremities to get rid of heat when they feel too hot, don't make the mistake of covering hands and feet during sleep;
  • Babies control their temperature mainly through their head. The best way to stop them overheating is to place them on their back with the head and face uncovered;
  • Sleep baby on their back;
  • Keep head and face uncovered;
  • Position baby’s feet at the bottom of the crib;
  • Use a tightly fitted sheet only that tucks under the mattress (try our new Baby Tuck Sheet); and
  • You've done some hard work growing and birthing a baby (understatement); treat yourself to a little bit of luxury with our Matchy Matchy Robe, ideal for winter days. 100% bamboo jersey fibers, pockets for mum-things, and in matching prints to your boo.
