Why Parents Love SNOO Sack

Arms-in

When using the SNOO sack with the baby\'s arms in, it helps prevent the startle reflex and keeps the baby\'s arms snugly wrapped. This can provide a sense of security and promote better sleep.

Arms-out

If you prefer to have your baby\'s arms out or if your baby shows signs of wanting more freedom of movement, the SNOO sack can also be used with the arms out.
