My baby’s arms wiggle free by pushing the SNOO sack's inner band up, to the top of his chest. How can I keep that from happening?


The SNOO sack’s inner band is specially designed to keep your little one from startling himself awake. And it also is one of the ways that SNOO secures your baby in place, to prevent risky rolling to the stomach. In fact, we are proud to share that SNOO has kept babies sleeping in the safe position - on the back - for over 100,000,000 hours. Nevertheless, some baby are little Houdinis! They squiggle and squirm and push the inner band up and off the arms…even all the way to the top of the chest.

The good news is that there are a bunch of ways to keep your little escape artist snug and safe:

  1. Check to make sure the inner band is positioned correctly
  • Make sure the band is very snugly closed. The lower edge should cover ½ of the hands…right over the knuckles. (It’s easiest if you first place your baby on the sleep sack - the shoulders about 2 inches above the sack - then pull the top of the swaddle up and over your baby’s shoulders.)
  1. Try double-swaddling
  • Swaddle your little one in a light swaddle blanket (arms down), then put them in the SNOO sack closing the inner bands on the outside of the swaddle blanket to keep the arms down. (Note: Check your baby’s ears...if they're red and hot or your baby's neck is sweaty, then your baby is too warm.)
  1. Wrap your baby’s arms with a thin cloth…before swaddling  
  • Place a thin cloth - like a large napkin or cloth diaper -  inside SNOO Sack and lay your baby down on top of it. Then, fold one side of the cloth over your baby's arm and tuck it snuggly underneath her body. Then, secure the inner bands around your baby’s belly and zip the swaddle up. (You can find photos of this technique in this blog post on swaddling.)
  1. Try a little freedom
  • It may be time to see if your baby would be happier with the arms a bit looser. Close the inner band around your baby’s chest...leaving the hands outside. This will keep the band from riding up. You can let the arms be snugly held inside the zippered sack or unsnap the arm holes and let an arm out.  Once your baby is comfortable with one arm out, you can repeat the process with the second arm.
