While you can dress your baby in a short-sleeve onesie as long as they’re very well layered, try to use long-sleeved onesies for the best coverage.
For the warmest pants, look for ones with that extend and cover the feet.
For example, once your baby has a long-sleeve onesie on, put on a pair of pants and a light, fleece sweater.
If you have a newborn, you’ll also need to wrap them in a blanket.
The hood should completely cover your baby’s ears as well. If it doesn’t, put a fleece hat on your baby’s head under the hood.
To make it easier to get your baby into their car seat in the winter, keep the seat in the house. Buckle the baby into it and lay the blanket over them. Then you can quickly carry the baby in the car seat to the car once you’re ready to go.
Choose a hat that has a Velcro strap and use it to secure the hat under your baby’s chin. This way they’re less likely to pull the hat off.
Avoid trying to put gloves on your older baby since it will be too difficult to get the individual fingers into them. If your newborn’s onesie has hand covers near the cuffs, fold them over the hands for an extra layer of protection.
It may be hard to find thick winter boots for small babies, so you may need to put several layers of socks under their booties if you can’t find boots.
Don’t use the temperature of your baby’s hands or feet to determine if they’re cold since these are normally a little cooler than the rest of the body.
The American Academy of Pediatrics recommends waiting until your baby turns 1 before putting a blanket in their crib. You can make your baby’s crib a little warmer by putting a flannel fitted sheet on the mattress in winter.
