What Do Newborns Wear to Sleep? 

One of the hardest things for me to figure out before my baby arrived was what she would actually wear to sleep. There are so many different options, and it can feel overwhelming trying to choose between swaddles, sleep sacks or some variation in between. 

I’ll be honest, I didn’t try every swaddle or sleep sack out there. But I want to share what worked for us and why, so you can decide what might work for you and your baby.

The Newborn Swaddle That Worked For Us 

The Love to Dream Swaddle UP was the first and only newborn sleep sack we used once we got home from the hospital and throughout the newborn stage. 

We tried the simple wrap swaddle from the hospital, but within a few days it was clear that wasn’t how our baby preferred to sleep. She would constantly work her arms out, and it just didn’t feel secure or sustainable for us.

Before trying Love to Dream Swaddle Up, one of my biggest issues with other sleep sacks was the sizing. They were so large on my newborn that she felt completely lost inside them, which made me uncomfortable using them. 

What I loved about the swaddle up is that it allows babies to sleep with their arms up, while still keeping a snug fit around the chest and torso. That snugness helps reduce the startle reflex, but still gives them some freedom to move.

Many babies naturally bring their hands near their face. This is common even before birth and can have a calming effect while supporting early body awareness and sensory development. This is part of how they begin learning to regulate themselves with self-soothing. 

Another huge benefit for me was peace of mind. Using a sleep sack instead of a wrap swaddle meant it couldn’t come undone overnight. I didn’t have to worry about loose blankets in the bassinet, which made me feel much more comfortable from a safety standpoint and honestly helped me sleep better too.

Safe Newborn Sleep

As always, make sure to follow safe sleep guidelines by placing your baby on their back in an empty crib or bassinet with no loose blankets or items.

Who The Love to Dream Sleep Sack Will Work For

• If your baby breaks out of traditional swaddles within minutes
• If your baby seems to prefer sleeping with hands up near their face
• If you’re struggling with the startle reflex constantly waking them
• If you want something quick and simple for middle-of-the-night changes
• If you don’t want to keep buying and trying multiple swaddles

This worked especially well for us because our baby kept breaking out of traditional swaddles and clearly preferred having her hands up near her face. If you’re dealing with frequent wake-ups from the startle reflex, or just want something simple that you don’t have to rewrap in the middle of the night, this is a really good option to try. 

Who The Love to Dream Swaddle Up Might NOT Work For

Some things to consider:

• Babies who strongly resist any feeling of restriction and prefer completely loose sleep
• Babies who strongly prefer arms-down sleep in a traditional swaddle and seem more settled in that position
• Babies who are already rolling consistently, since arms-up swaddles may not be appropriate at that stage
• Moms who prefer to skip swaddles altogether and go straight to arms-out sleep

While the Love to Dream swaddle worked really well for us, I know every baby is different. If your baby prefers a more traditional, snug swaddle with their arms down, the HALO SleepSack Swaddle is another really popular option that many parents love.

When to Stop Swaddling (Quick Guide)

Swaddling can be really helpful in those early newborn weeks, but there does come a point when it’s time to stop.

A good general rule is to stop swaddling once your baby shows signs of rolling. For some babies this can happen as early as 2–3 months, even if they’re not rolling consistently yet.

Here are a few signs it might be time to transition:

• Your baby is starting to roll (or attempting to)
• They’re breaking out of the swaddle frequently
• They seem frustrated or fighting the swaddle
• They’re becoming more active during sleep

Once you notice these signs, it’s usually best to switch to a sleep sack that allows for free arm movement.

For us, this transition felt pretty natural once our baby needed more movement and started rolling.

 What’s Next?

Once our baby outgrew the Love to Dream Swaddle UP, we transitioned to the HALO SleepSack, which we’ve now repurchased in a larger size at 6 months.

At this stage, I can honestly see this being the sleep sack we stick with until we eventually transition to blankets. The HALO SleepSack was an affordable option for us, and it worked really well.

What I like about it is that it still keeps things simple with an easy zipper for night changes, but it’s much less restrictive. It also allows more freedom of movement, which felt important as she started rolling and needing her arms free.

Swaddle vs Sleep Sack: What’s the Difference?

Swaddles are typically more restrictive and designed for the newborn stage to help reduce the startle reflex. Sleep sacks are wearable blankets that allow more movement and are often used as babies get older.

Some products (like the Love to Dream Swaddle UP) fall somewhere in between, offering a snug fit while still allowing some movement.

What to Look for in a Newborn Sleep Sack

When choosing a sleep sack or swaddle for a newborn, a few things really matter:

• A snug (but not tight) fit around the chest to help with the startle reflex
• Safe sizing so your baby isn’t swimming in excess fabric
• Ease of use, especially for middle-of-the-night changes
• Your baby’s natural sleep preference (arms up vs arms down)

Every baby is different, so sometimes it takes a little trial and error but focusing on these basics can make the process a lot less overwhelming.

Common Questions About Newborn Sleep

Do newborns need a sleep sack?

Not necessarily, but many parents find them helpful for safer sleep and easier routines.

Can newborns sleep with blankets?

Loose blankets aren’t recommended for safety so sleep sacks are a safer alternative.

How should I dress my newborn under a sleep sack?

It depends on the room temperature, but typically a simple footed sleeper or onesie underneath is enough. If you are unsure, many companies (like Love to Dream) provide general temperature guidelines based on the particular swaddle or sleep sack you purchase. 

When should I stop using a sleep sack?

Sleep sacks can be used well into the first year (and beyond), as long as your baby is comfortable and the size is appropriate. Many parents continue using them until transitioning to blankets later on.

Reminder

The products I share are based on my personal experience with my baby. What worked really well for us may not be the perfect fit for every baby, since all babies have different preferences and sleep styles.
