If it’s snowy or rainy outside, go for a waterproof outer layer. Otherwise, cotton or wool outer layers will keep your baby warm and cozy all day.

If your baby will be playing in the snow, make sure their gloves or mittens are waterproof. In very cold temperatures, like anything below 35 °F (2 °C), it’s best not to stay outside with your baby too long. They can’t regulate their temperatures like we do, and they get cold much faster.

Remember to remove any blankets before putting your baby down for a nap or when they go to bed. Sleep sacks are okay, but loose blankets can be dangerous for your baby to sleep with.

Be sure to leave your baby’s face uncovered so they can breathe in the car seat.

In general, if you feel too warm and need to take off a few layers, your baby probably does, too.

A good rule of thumb is to look at how many layers you’re wearing, and then add one more for your baby. When you and your baby are lounging at home or they’re going to sleep, you can even undress them down to their diaper. [6] X Research source

Make sure the hat doesn’t have any sort of ties or ribbons that could unravel around your baby’s neck, since that could be a choking hazard. [8] X Research source

If you have your baby in a stroller outside, make sure the cover is up to keep them out of the sun.

Babies tend to run slightly cooler than we do, which is why they often need that one extra layer.

In general, your baby’s body temperature should be between 98 and 100 °F (37 and 38 °C).

If you’re adjusting your own outfit by adding or removing layers, you probably need to do the same for your baby.
