As babies grow, so do their sleep habits—and just when you’ve finally figured out the swaddle, your little one starts to roll! It’s a milestone worth celebrating, but it also signals an important shift in how we keep our babies safe while they sleep. If you’re wondering whether it’s safe to keep using a baby sleep sack after your infant starts rolling, you’re not alone—and the short answer is: yes, it is, with the right type of sleep sack.
What Is a Baby Sleep Sack?
A baby sleep sack, sometimes called a sleep bag or newborn wearable blanket, is a safe, cozy alternative to loose blankets. Designed like a wearable sleeping bag, it helps babies stay warm and secure throughout the night without the suffocation risks associated with traditional bedding. These sacks come in a variety of fabrics, styles, and sizes, and many are designed to accommodate babies as they reach new milestones, including rolling over.
Are Sleep Sacks Safe After a Baby Starts Rolling?
Yes! In fact, sleep sacks remain one of the safest sleep solutions for rolling babies, as long as they allow full arm mobility. Once your baby can roll from back to front, it’s essential to transition away from swaddles or any sleepwear that restricts their arms.
Here’s what to look for:
- Sleeveless design: A sleep sack with open armholes allows your baby to push up, reposition, or roll safely during the night.
- Proper fit: The sack should be snug around the chest and neck but roomy around the hips and legs for natural movement and healthy hip development.
- Lightweight fabric: Look for breathable options to prevent overheating. Cotton or cotton-blend sacks are especially great for temperature regulation.
Avoid any weighted sleep sacks or swaddle-style sacks with velcro or fasteners once your baby starts rolling—they can prevent your baby from moving freely and may increase the risk of suffocation.
