14 Best Baby and Toddler Sleep Sacks for a Night of Sweet Dreams
February 9, 2021
It’s natural to want to keep baby cozy and warm, but putting a blanket in baby’s crib before their first birthday is a big safety no-no, since it can pose a suffocation hazard and increase the risk of SIDS. But that doesn’t mean your little one has to be cold. Wearable blankets—aka sleep sacks—replace loose bedding while still keeping your child warm. They come in different designs (with zippers or secure wraps, sleeved or sleeveless) and fabrics and can safely be worn from infancy through toddlerhood. So which sleep sack should you get for your kiddo? Here, we’re serving up the best options for every stage of baby’s life.
The Halo SleepSack is by far the one that most parents swear by. It unzips from the bottom for quick and easy middle-of-the-night diaper changes, and the roomy sack design provides plenty of space for rambunctious baby kicks. It comes in a wide variety of sizes and colors and even offers a style with foot holes for little walkers.

The SwaddleMe is a baby sleep sack-swaddle hybrid that makes swaddling newborns a breeze, thanks to the brilliant wing-wrap design and hook and loop fasteners. Made from 100 percent cotton, this swaddle sack creates a tight swaddle that keeps baby warm and cozy and helps prevent an infant’s startle reflex. Available in a wide range of colors and patterns, the SwaddleMe comes in a pack of three so you’re sure to always have at least one clean one on hand.

The Merlin’s Magic Sleepsuit is essentially a super-cushioned, footless one-piece for babies who are ready to break out of the swaddle (often around 3 months of age). The sleepsuit works by muffling the small movements that would otherwise wake them up, thereby resulting in a longer period of uninterrupted sleep for baby (and mom).

The Nested Bean Zen Sack is a lightly weighted sleep sack that works by mimicking a parent’s touch. The pressure pads in the center of the sack are safe for babies as light as seven pounds. The sack is also reversible for older tummy sleepers who can roll independently. The Zen Sack is available in classic cotton, a bamboo blend and a winter weight cotton with a heavy poly-fiber filling.

For the winter months, keep baby nice and toasty in Halo’s micro-fleece version of their ever-popular sleep sack. Made of 100 percent polyester micro-fleece, it’s the same style as the classic Halo, including the generous cut for fast-kicking legs and the top-to-bottom zipper to make diaper changes a breeze.

aiden + anais is many parents’ go-to company for muslin baby products, and their sleep sack options are no exception (though they refer to them as baby sleeping bags). The 100 percent cotton muslin is incredibly soft and breathable and comes in a variety of adorable patterns.

You might recognize the Zipadee Zip from Shark Tank, but this baby sleep sack is a definite winner in the “best with sleeves” category. The starfish design of the Zipadee Zip encloses both baby’s hands and feet, which provides a comforting, enclosed feeling similar to the swaddle while also allowing for full range of motion.
Buy it: Zipadee Zip, $39, Amazon.com
When frigid winter temps set in, make sure you have a Gunapod Sleep Sack on hand. The Gunapod is essentially a duvet cover that your child can safely wear: It’s made of silky soft bamboo with a down-like hypoallergenic filling. It’s also the only sleep sack with the option to fully open from the bottom, ensuring that baby stays toasty and that diaper changes are a snap.

For the warmer months, opt for a Bebe au Lait cotton muslin sleep sack. The breathable 100 percent cotton muslin keeps baby from getting overheated at night, and the machine-washable fabric just gets softer the more you wash it.

If you’ve got a kid who is on the move but not quite old enough to sleep with a blanket, the baby deedee sleep sack is just the solution. The fleece sleep sack has legs so your walker can keep warm while they’re on the move. The baby deedee comes in multiple sizes and is suitable for 18 months to 4T.

For a baby sleep sack made of all-natural materials, there’s no better choice than the Woolino. Made of luxuriously soft merino wool, the Woolino regulates baby’s temperature all year round and comes in a universal size that fits babies from 2 months to 2 years old. It’s also 100 percent natural and machine washable. The only drawback is the $100 price tag—but fans of the Woolino swear it’s easy to sell second-hand once your little one outgrows it.

The Burt’s Bees Baby Wearable Blanket is crafted from super-soft, 100 percent organic cotton. Available in a number of charming colors and patterns, the Burt’s Bees sleep sack features a zipper that opens from the bottom (to make diaper changes quick and easy), plus an interior zipper guard and a snappable zipper cover. The organic cotton is an ideal choice for little ones with sensitive skin.

Cover both your swaddle and sleep sack bases with the Halo SleepSack Swaddle combo. The brilliant design features a sleep sack with attached wings that Velcro around baby’s torso, and can be used from birth. Swaddle baby with arms in to prevent the startle reflex, and transition to arms out as they get older. The bottom-up zipper allows parents to change baby’s diaper without having to unswaddle.
