Keep Baby Warm at Night! Dressing Your Kids for Cold Weather

There is nothing cozier than a crisp fall night! I always looked forward to cooler night time weather, but soon after having kids I constantly wondered “how can I keep my babies warm at night?” As a new mom I wasn’t sure the best way to dress a newborn, infant or toddler to stay warm without putting a blanket in his or her crib!? 

Thankfully after three children I found a solution that works!

Over the years I’ve tried different sleep sacks, onesies and wool outfits and found essentials we can’t live without. With 3 babies, we had to learn how to dress our kids for all different kinds of weather!

We want our baby to be safe at night, but like any first time mom I worried “Is she too hot?” or “Is she too cold?”

So in this post I’m sharing with you three ways to keep your kids warm at night during the winter without blankets or chemicals. I also have a special discount code for one of the sleep sacks, you don’t want to miss it below!

These tips can be used for babies as well as older kids.

Our 3 year old son never kept a blanket on at night! We had to get creative so we weren’t going into his room every hour to adjust his blanket since he was getting cold.

We don’t keep an extremely warm house in the fall and winter months and for safety reasons we didn’t put blankets in the cribs when our kids were infants. 

So what are the best ways to keep your baby warm at night?

Here are the three ways we keep our kids warm in winter. Also note, we try our best to avoid flame retardant pajamas. They are often soaked in chemicals and can impact your children’s health.

First option, the sleep sack.

For warmer weather we love the cotton HALO SleepSack or the Burt’s Bees Baby Organic cotton sack. I like that these are made from 100% cotton and they are the perfect top layer with long sleeved pajamas.

Through the years, we have used sizes ranging from about 1 month old to 2-2.5 years of age.

The sacks are super cozy and since our kid’s did not like to be swaddled it was a good alternative to a blanket. These are the right thickness to be used for fall or spring weather, but once it gets colder you’ll want something warmer. 

A warmer option is the Woolino 4 Seasons Wearable Blanket (2 months to 2 years). They also have it in a toddler size (from 2 to 4 years of age).

Now for Your Special Discount Code!

If you are an Amazon shopper you can purchase the wearable blanket here.

Or you can buy right from Woolino.com and use my special discount code INSPIREDMOTHERHOOD10 to get 10% off your order.

I know, it’s expensive and I hesitated to buy it, but it was SO worth the investment. It is incredibly soft and cozy.

These are so worth the investment!

And we’ve used it with multiple kids. Better yet, we could still probably sell them to someone else when we are done. They have stayed in remarkable shape!

Our children have loved sleeping in their Woolino sleep sacks and now I recommend it to any new mom. You can actually wear them year round and they have held up through multiple kids using them in our family.

Besides the durability and coziness I recommend the Woolino options because the merino wool helps regulate children’s body temperature and we use it year round. We used the toddler size sack until our son was 3.5 years old.

Again if you want to buy from Woolino.com use my discount code INSPIREDMOTHERHOOD10 to get 10% off your order!!

He loved it and again I didn’t have to worry about the blanket falling off him at night. And him waking me up because his blanket was “messed up.” This mama loves her sleep! 

Clever ways to keep your baby or toddler warm at night without needing a blanket! Create a safe sleep environment for your baby.

Another warmer option is the fleece HALO SleepSack. It’s less expensive which is a plus and it’s cozy. Though it could possibly be easier to overheat in because it doesn’t breathe like cotton or merino wool. So we alternated this with the wool sleep sack. 

BONUS TIP: Consider the crib sheets or toddler sheets you are using for your kids.

We typically like Burt’s Bees Baby crib sheets because they are a soft 100% organic cotton jersey material. Plus they won’t break the bank. Though in the winter I’ve used some organic flannel sheets and 100% cotton flannel sheets. It does seem to make the bed extra cozy!

Second option, layer clothing!

We chose this option when our son was first born. He didn’t like being swaddled and I wasn’t sure how to keep him warm at night. So I’d put a snug Burt’s Bees Baby onesie or bodysuit on first, then layer with a warmer sleeper.

We also love the Hanna Andersson pajamas. They are so cozy and a bit thicker. For the spring and fall this was perfect.

For cooler months you may want to consider a merino wool coverall. We used this with our daughter and son. It was snugger than a sleep sack (which made me feel like it was a bit safer) and the wool helped regulate their temperature. So they never got too hot or too cold.

This is the one we used, but I also like the Disana pants and the Engel romper. Again these will be investments, but you can use it for years to come and with multiple kids.

Third option, wool pajamas.

Above I shared our favorite wool sleep sack and wool overall, but the other option is wool pajamas. There are so many to choose from so how do you find the best? We love merino wool because it is breathable and provides natural temperature regulation (see more benefits here). 

It is more expensive than cotton pajamas, but you don’t have to wash it as often and it dries quickly! Instead of buying 10 footed pajamas buy 1 or 2 wool pieces and you are set. Again you can wear the wool night after night without washing it. Also it’s more absorbent than other materials.

So when my son used to leak through his diaper at night, it wouldn’t get all over his crib with the merino wool. And yes we’d wash the wool if got covered in baby fluids!

  1. I am so happy you are following safe advice with no bumpers, toys or blankets in your babies crib. Thank you for doing that. I see too many blogger moms posting pictures with their babies in unsafe cribs I just want to scream.

    1. Oh gosh I thought about that since the picture shows my daughter sleeping on her tummy. Though at this age she was old enough to roll both ways and she always preferred her tummy.

  2. We have always done sleep sacks!! As she is almost 1, I think about letting her sleep with a blanket now, but she just moves around so much I know it won’t stay on her! The slee sacks are perfect!
