An Overview On Baby Sleep Sacks

While swaddling blankets wrap around babies to keep them feeling snug and secure, they usually loosen. Worse still, if they are wrapped too tightly, it limits the baby’s mobility. Sleep sacks (also called sleep bags) are made of thicker material, and they provide that snuggly feeling without limiting mobility. They are basically like wearable blankets, with zippers for when diaper changes are needed.

Experts feel that sleeping sacks can help babies snooze longer, and that makes parents, caregivers, babies and their siblings happier. Some of these outfits have sleeves, while others are sleeveless and fit right over whatever the baby is already wearing. When the weather is cool, a full-sleeved option will keep them warmer.

Look for soft, natural materials like 100%cotton when shopping for baby sleep sacks. Also read about where the zipper is located; some zipper from the bottom up. You don’t want to be scrambling around when baby needs a clean diaper.

The Baby Sleep Sack Buying Guide

  • Choose a sleep sack that is appropriate for your baby’s weight and size.
  • The sack should fit comfortably around the baby’s neck, shoulders and torso, and it should not be tight.
  • The sleep sack’s neck opening should not be too big; you wouldn’t want your baby to slip down inside.
  • The arm holes on a sleep sack should not be big enough to allow the baby to get their hands inside the body of the outfit.
