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.

DWYM Fun Fact

Did you know that newborns sleep between 14 and 17 hours a day? Here are a few more fun facts about babies and sleep.

  • Infant sleep cycles last between 50 and 60 minutes. This is much shorter than an adult sleep cycle, which averages 90 minutes.
  • Newborns up to 3 months get their days and nights mixed up because their circadian rhythms haven’t fully developed.
  • You can start a bedtime with your baby as early as 6 to 12 weeks. You can give your baby a bath, apply a soothing moisturizer and sing a song or read a book. Consistency is key in teaching your baby it’s time to go to sleep.

The Muslin Sleep Sack Tips and Advice

  • 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 SwaddleDesigns 2-Way Zipper Muslin Sleep Sack has a 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.
