From The Manufacturer

Halo SleepSack Wearable Blankets are the #1 trusted choice of hospitals and are used to help babies sleep safely from the start. In addition to sleeping safer, it helps babies sleep better, too. It's a warm cuddly blanket they can't kick off; ensuring baby sleeps soundly throughout the night, with a unique, roomy sack design recognized by the International Hip Dysplasia Institute as "hip healthy." Inverted zipper opens from the bottom for easy diaper changes; sleeveless to reduce the risk of overheating; arm and neck openings sized for a safer fit. Made with two layers of lightweight and ultra-soft 100% cotton muslin with a TOG rating of 0.5, this Sleepsack offers just the right comfort for warmer seasons or climates, and can be layered with warmer sleepwear for cooler temperatures. Cotton muslin is exceptionally breathable for optimal airflow, reducing your baby's risk of overheating and ensuring comfortable sleep. Size X-Large is designed for babies weighing between 26 and 36 pounds who are generally 18-24 months old and 35-40 inches long.

An Overview On Muslin Sleep Sacks

Sleep sacks not only provide a sense of security for babies, but they also help little ones keep a consistent body temperature throughout the night. Additionally, they negate the need for loose blankets, which can pose a suffocation risk for infants. If you’re in the market for a few sleep sacks, you’ll want to keep the following features in mind as you shop.

Review the sleep sack’s fabric first. Premium cotton is the best way to go, as it gets softer with each wash. Some sleep sacks even come pre-washed, so they are soft against baby’s skin from the very first use. You also need a breathable fabric, like cotton, as this keeps your baby from overheating.

Look for a two-way zipper next. This feature makes the sleep sack easy to slip on and off. It also provides quick access for diaper changes, eliminating the need to remove the entire garment.

Check that the sleep sack comes in a variety of sizes. For safety, it’s important that your baby is placed in the correct size. Never go with a one-size-fits-most model. You’ll find most sleep sacks are available in 0-6 months, 6-12 months and 12-18 months.

Consider the print once you’ve narrowed down your choices. There are pink flowers for girls, blue dots for boys, as well as gender-neutral patterns, like gray stars, yellow giraffes and orange foxes.

The Muslin Sleep Sack Buying Guide

  • Check the manufacturer’s instructions before laundering your sleep sacks. Typically, it’s best to wash your infant’s clothing items separately from the rest of the family, using a mild detergent that is either all-natural or listed as safe for sensitive skin.
  • The ideal room temperature for your baby is between 68 and 72 degrees Fahrenheit. At this temperature, your baby won’t need any blankets in addition to the sleep sack.
  • Riley Children’s Health recommends placing baby flat in his or her crib or bassinet. Make sure the sleep space is free of toys and blankets.
  • Once your baby begins to crawl, you may wish to switch from the muslin sleep sack to footed sleepwear. This will prevent the baby from becoming discouraged if he tries to move around with the sleep sack on.
  • Muslin sleep sacks vary in price, so you’ll want to check the tag before making a final decision. The Hudson Baby Sleeveless Muslin Sleep Sack is the most affordable, while the SwaddleDesigns 2-Way Zipper Muslin Sleep Sack has a more moderate cost. You’ll pay a higher cost for the Amazing Baby 2-Way Zipper Muslin Sleep Sack, which comes in an attractive gift box.
