Everything you need to keep your baby warm this winter

As temperatures drop, it's natural to feel worried about keeping your baby warm enough, especially newborns who aren't as good at regulating their own temperature as older babies. But it isn't difficult to keep your infant warm if you have the right gear. 

While thick garments are handy for freezing temperatures, on most cool days, it's better to dress your baby in a range of layers. And of course, you need to keep your baby warm at night as well as in the day. 

In this article: Halo Sleepsack Wearable Blanket, Happy Cherry Baby Snowsuit and Burt's Bees Baby Organic Cotton Bodysuits.

What should babies wear outside?

It's important to find a balance between keeping your baby warm and making them too hot. What they need to wear depends on the temperature, but you should always start with a bodysuit as a base layer. On top of this, footies or onesies are ideal — and you can find different thicknesses, depending on the temperature. Hats and mittens are great for cold days, and you can add a snowsuit if it's extremely cold. 

What should babies wear at night?

How much your baby needs to wear at night depends on the temperature of their room rather than what's outside. In a warm room, kept about 75 to 80 degrees, they only need a bodysuit and a light sleep sack. However, in chilly rooms of 60 to 65 degrees, they need a bodysuit, footie pajamas, socks, a hat and a heavy sleep sack. Adjust for temperatures between these extremes, and look out for signs that your baby is getting too hot or cold. 

What you need to keep your baby warm in winter

These are some of the items you need to keep your baby warm this winter: 

  • Bodysuits: Bodysuits are essential base layers that provide the first line of defense against cold. You should have a range of long- and short-sleeved versions. 
  • Footies: Footies, sleepsuits, jumpsuits or whatever else you call them, these garments are versatile and cozy. 
  • Hats: Hats keep babies from losing heat through their bare heads and are perfect for outdoor use. You can also find lightweight hats that are great for indoor wear on cold nights. 
  • Socks: When temperatures drop, simply adding a pair of socks to your baby's outfit can make a big difference.  
  • Mittens: Mittens keep little hands warm while outside or on exceptionally chilly nights. 
  • Snowsuits: Sometimes called bunting suits, these thick, padded onesies are great for babies to wear outside in extremely cold weather. 
  • Footmuffs: Stroller footmuffs act as a kind of blanket to keep your baby warm in a stroller, but unlike loose blankets, they can't be kicked off. 
  • Sleep sacks: Also known as wearable blankets, sleep sacks for babies are perfect for nighttime use. Loose blankets increase the risk of sudden infant death syndrome, but sleep sacks are designed so they can't cover babies' noses or mouths and pose a suffocation risk.
