My baby is sliding into the SNOO sack. How can I prevent that?

The SNOO sack’s inner band is specially designed to keep your little one from startling awake. It also 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 150,000,000 hours. Nevertheless, some baby are little Houdinis! They squiggle and squirm and can sometimes wiggle further down into the SNOO sack.

Fortunately, there are several easy ways to keep your baby perfectly secured in the right place:

Use a thin cloth to wrap your baby’s arms…before swaddling

Place a thin cloth - like a large napkin or cloth diaper -  inside the SNOO Sack. Lay your baby down on top of it and fold one side of the cloth over each arm and tuck it snuggly underneath the body. Then, secure the inner bands around your baby’s arms and belly and zip the swaddle up. (You can find photos of this technique in this blog post on swaddling.)

Double swaddle

Swaddling in a thin swaddle - before securing the inner band around your baby in the SNOO Sack - is another great way to keep arms swaddled and help snug your baby to prevent the wiggling. (Just remember, when you swaddle, keep the arms snug, but allow tons of room around the legs so the hips can flex and open. Also, check to make sure your baby is not overheated by using the simple little tip described in this FAQ.

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 keep the arms 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.
