As an alternative to blankets, sleep sacks can be wrapped around your infant to create a cozy enclosure with room for arms and legs to move freely. A blanket will not be able to cover your baby’s face if they are in a bag. These are constructed of bamboo rayon, which is lightweight and breathable. It feels silky and smooth against the skin, with a hint of stretch for enhanced comfort.

It’s also kind to the environment, as it’s ethically sourced and produced from sustainable bamboo. The sleeping bag zips in two directions: top-to-bottom and bottom-to-top, making it easier to change.

3. Little Unicorn Cotton Muslin Sleep Bag

Little-Unicorn-Cotton-Muslin-Sleep-Bag

Sorry, but these Muslin Sleep Bags from Little Unicorn are so darn lovely. I like that the Muslin is incredibly breathable and cool, but it’s just 1.0 tog, so it’s still suitable for layering on a Spring or Autumn day!

Our sleep bags are a safe and fashionable alternative to blankets because they are lightweight, breathable, and feature artisan hand-painted prints. The top-to-bottom zipper makes changing diapers at night a breeze, and the machine-washable cotton muslin gets softer with each wash.

4. Love to Dream Swaddle UP Original

Love-to-Dream-Swaddle-UP-Original

This inventive hybrid is a great option for babies who don’t like the tightness of a traditional swaddle blanket but aren’t quite ready for a sleep sack. The Swaddle UP allows your child to sleep with their arms up, which is a natural position that also allows them to use their hands for self-soothing.

It’s smooth and breathable, easy to use, and, needless to say, makes every baby look even cuter than usual while wearing it. Unlike classical arms-out sleep sacks, which can be used well into toddlerhood, you’ll have to give this one up once the baby starts rolling over on his or her own.

5. Baby Merlin’s Magic Sleepsuit Cotton Swaddle Transition Product

Baby-Merlin's-Magic-Sleepsuit-Cotton-Swaddle-Transition-Product

This sleepsuit may transform your child into the Stay Puft Marshmallow Man, but we promise the laughs will be worth it. Many babies struggle to adjust from the snugness and security of a traditional swaddle to the roominess of a sleep sack. The Merlin is the ideal middle ground. It’s soft enough to allow the baby some movement while also being heavy enough to suppress the startle reflex, allowing many babies to sleep longer and sounder.

When using the Merlin, there are two things you should keep in mind. First and foremost, it is warm. Instead of wearing heavy PJs underneath, dress baby in a short-sleeved bodysuit.
