Before my son was born, I had never heard of a baby sleep sack. I was sure I’d be a Master Swaddler. I read about all of the benefits of swaddling. I knew it could help my son sleep longer and more soundly. I practiced swaddling with square blankets and stuffed bears.
And then, my beautiful, wiggly son was born. In reality, I didn’t have the bandwidth to become a swaddle expert on my wiggling newborn. I couldn’t get them tight enough that it helped at all. I had a fleece HALO sleep sack, but my son was born during a heat wave in May, and it was much too hot for him to wear it. One night, days after he was born, my mom and I had been awake for hours trying to console my newborn. Finally, we turned on our AC, wrapped him in the HALO sleep sack, and placed him in the pack n play. I swear he instantly fell asleep. Instantly. It was real-life magic. From then on, I’ve been sold on the baby sleep sack.
Three years later and my son is still wearing a sleep sack. Though it looks a little different than the newborn ones, it serves the same purpose– to help my kiddo sleep better. Here are my favorite ones to date.

Best baby sleep sacks-- before they're rolling
These one-step pre-assembled swaddles helped my son sleep much longer, which meant I could sleep much longer, which made everything better.
Before babies are rolling, it is safe to wrap up their arms so they sleep more soundly. As soon as they can roll, it’s no longer safe (but you can still use sleep blankets! Read more below).
Perfect for cold weather. Toys and games that allow them to work their muscles, grow their brains, and practice independence.
Great for wiggly newborns.
Can easily be used with hands in or out.
Magic Mom Hack
You can easily adjust the HALO sleep sacks with “wings” to just wrap around their torso once your baby starts rolling, if it still fits.
Weighted front section. It has a super cool weighted bean bag on the chest of it, which mimics the closeness to mom.
Wraps high around shoulders. My son slept best when his arms and shoulders were also in the swaddle, so this one was perfect.
Wiggle-proof. Since this one is all one piece, even the wiggliest of wiggly babies can’t bust out of this one.
Great for babies who don’t like to be completely wrapped up. Some newborns do better when in a swaddle blanket but don’t want to be so restricted.
Promotes self-soothing. This design allows babies to move their hands to their face without breaking free of the swaddle.
Weighted sleep suit. Known to help babies sleep more soundly.
For infants 3-6 months old who are not rolling. The Merlin’s Magic Sleepsuit can be worn when a baby is 12 pounds and 3 months old (check out their sizing guide here). However, they are no longer safe to use once a baby is rolling over. My son started rolling at 2.5 months old so we never got to use these ourselves. I recommend waiting to purchase this until your kiddo hits the recommended size limit.
Best baby sleep sacks-- after they are rolling
Design perfect for babies who need a safe blanket and no longer need to be swaddled.
Perfect for warm weather.
There are only a few years where our kiddos will permit us to rope them into (adorable) family costumes, so we have to take advantage of that while we can. There are an infinite number of costumes on the market for kids, but many of them need to be hand washed.
Raise your hand if you’ve got time to hand wash costumes.
There are some wonderful doctor toys for kids on the market now that can help you bring a doctor’s office right into your home. These toys can help children gain some control by allowing them to take a step into the driver’s seat, so to speak. Plus, they can practice empathy and creativity as well.
