How to keep your baby warm in winter weather

When temperatures drop, babies rely on caregivers to protect them from the elements. Infants can’t regulate their body temperature as well as older children. Before taking a baby outside in cold weather, dress them in layers to keep them warm.

Layers allow for adjustments, so your baby doesn’t overheat. The base layer should be snug, such as a onesie and leggings. You can layer a long-sleeved outfit over that, such as a sweater and pants. Top it off with a warm jacket, hat, mittens and booties.

Warm blankets are also key, whether you’re taking your baby out in the stroller or keeping them cozy at home in a wearable blanket.

Winter baby clothing

Winter bodysuits

Onesies or baby bodysuits for cold weather feature long sleeves. A cotton or bamboo long-sleeved onesie is breathable and perfect for layering. For sleeping, a one-piece footed sleeper keeps your baby warm and covered from neck to toe.


Baby leggings are perfect for pairing with onesies, long-sleeved shirts, sweaters or all of the above to cover the bottom half of your baby. Leggings are snug enough to fit under pants, dresses or snowsuits.


Baby sweaters come in pullovers, cardigans and zippered styles. Wool is the warmest material for sweaters, and it is also safe for sensitive skin. Plus, the natural fiber is moisture-wicking. There are many cute styles of baby sweaters.


A warm jacket is a must-have for winter. Buy one that will fit over the other layers, including bulky sweaters. Puffer jackets and fleece jackets are the most common baby coats. Puffers are thicker and must be taken off before strapping your child into a car seat. Both types of jackets keep babies warm and are easy to take on and off.


Also called jumpsuits, snowsuits are the warmest option for babies. And there doesn’t need to be snowy conditions to put your baby in this one-piece. They’re also a great buffer against the cold. They offer full coverage and include a hood. The warmest ones are down-filled and feature fleece lining. Appropriate for outdoor excursions, don’t leave your baby in one too long indoors, or they might overheat.

Winter baby accessories


Baby beanies are by far the most popular style of hats for babies. They can be pulled over your baby’s ears, which are prone to frostbite, and fit snugly around the head. Fleece and wool beanies are the warmest materials. If you’re taking your baby indoors on errands, you can easily remove their hat to keep them from overheating.


Keep little digits warm and safe from frostbite with mittens. The mitten’s material and whether or not it’s lined will determine how warm they are. In addition to hats, this accessory can be easily removed when you take your baby indoors to prevent overheating. Baby mittens have an elastic or Velcro closure at the wrist.


Lastly, winterproof your baby down to its toes with cozy booties. Booties are a cross between slippers and shoes, like a more structured sock. Fleece is a popular material for this footwear. Select booties feature leather or pleather exteriors. Buy booties that cover the ankle. Some may feature rubber or non-slip soles for toddlers.

Baby blankets


If your baby is under a year old, the American Academy of Pediatricians does not recommend that they sleep with blankets to reduce the risk of Sudden Infant Death Syndrome (SIDS). Instead, on chilly nights put your baby in a wearable blanket that won’t suffocate or get tangled around your baby.

Bunting bag

To keep your baby warm and safe on extra chilly days, a bunting bag attached to a stroller or car seat zips up like a little sleeping bag.
