How to Keep Your Newborn Warm Without Overheating
Bringing your newborn home comes with a lot of questions, and one that comes up often is: “How do I keep my baby warm without risking overheating?”
Have you ever been out in winter wearing so many layers that halfway through you start thinking, “I definitely overdid it,” because you’re getting too warm (and maybe a little cranky)? Newborns can’t regulate their body temperature the way we can, so they rely on us to keep them comfortable.
Here are some simple ways to help your baby stay cozy and safe.
Dress in Layers
Think about how you dress yourself. Wearing layers feels more comfortable and helps you adjust easily and the same goes for your baby.
Start with:
A soft, breathable cotton onesie as the base layer
Add a light sleep sack or wearable blanket on top
As a general rule, dress your baby in one more layer than you’re wearing for the same temperature
This helps keep your baby warm without trapping too much heat.
Choose the Right Fabrics
This is a big one. Natural, breathable fabrics like cotton, bamboo, or muslin are great for helping regulate your baby’s temperature. These materials wick away moisture and prevent overheating.
Try to avoid polyester or fleece for sleep, since they tend to trap heat and make it harder for your baby to cool down if they get too warm.
Skip Hats and Mittens Indoors
They’re adorable (we know) but hats and mittens are usually unnecessary inside. Babies release heat through their heads and hands, so covering those areas can actually cause overheating.
Save the hats for outdoor walks or chilly outings, and let your baby’s body naturally regulate their temperature indoors.
Keep the Room at a Comfortable Temperature
Your baby’s nursery should stay between 68°F and 72°F.
A few tips:
Use a simple room thermometer to monitor the temperature
If needed, use a space heater with a thermostat to keep things consistent (just keep it far from the crib)
Avoid placing the crib next to windows, vents, or direct heat sources where the temperature can fluctuate
Watch for Signs of Overheating
Keep an eye out for signs your baby might be too warm:
Damp hair or sweating
Flushed cheeks
Fast breathing
Heat rash
You can also gently touch the back of your baby’s neck or chest. If they feel sweaty or hot, remove a layer and check the room temperature. Don’t panic, small adjustments usually fix the problem quickly.
Follow Safe Sleep Guidelines
Safe sleep practices are just as important for your baby’s comfort and safety:
Always place your baby on their back to sleep
Keep the crib free of pillows, blankets, and toys
Use a firm, flat mattress with a fitted sheet only
Following these guidelines helps reduce the risk of overheating and supports safer sleep.
A Gentle Reminder
If your little one seems cozy, isn’t sweating, and is sleeping well, you’re doing a great job. Trust your instincts, keep things simple, and know that you’re providing exactly what your baby needs.
