FAQs About Sleep Bags
What is a baby sleep sack?
A baby sleep sack is a wearable blanket that keeps your little one warm and cozy during sleep without any loose bedding in the crib. It zips or snaps around your baby, leaving their arms free while keeping their body and legs snug. Our sleep sacks come in a range of TOG ratings, sleeve styles, and eco-friendly fabrics so you can find the perfect fit for every season.
What TOG rating should I choose for my baby's sleep sack?
Use your baby's room temperature as your guide. A 0.25–0.6 TOG suits warm rooms (24°C+), a 1.0 TOG works well for average temperatures (20–24°C), a 2.5 TOG is ideal for cooler rooms (16–20°C), and a 3.5–4.0 TOG will keep them cozy in a cold room. Nest Designs sleep sacks are available from 0.25 all the way up to 4.0 TOG.
At what age can a baby use a sleep sack?
Right from day one. We offer newborn sleep bags for the tiniest of babies, and our sleep bag range extends right through toddlerhood with footed sleep bags for bigger little ones. The most important thing is that the sleep sack fits properly. The neck and armhole openings should be snug so your baby stays safe and comfortable.
Are sleep sacks safe for babies?
Yes. Sleep sacks are widely recommended as a safe sleep option for babies. They remove the need for loose blankets in the crib, which can pose a risk for young babies. Our sleep sacks are made from breathable bamboo blends with a relaxed fit that lets your little one move freely and comfortably through the night.
How do I know when my baby has outgrown their sleep sack?
It's probably time to size up when your little one's feet reach the bottom of the bag, the neck opening feels snug, or they seem cramped inside. When your little bub outgrows their sleep bag, our footed toddler sleep bags are the perfect next step—designed for all the wiggling, exploring, and climbing that comes with the toddler years.
