The best swaddle design, easy to clip arms in and do up one handed if baby falls asleep after feeding. The print is cute and gender neutral too. Flexible fabric allows our wriggly baby to move whilst still feeling secure, helping her learn self settling.

This is my newborn’s favourite swaddle bag as loves his arms out when he sleeps. Easy to wash and dry and the quality is amazing!
- Steve C.Verified Buyer1 month agoReviewingCocoon Swaddle Bag 1.0 TOG Oatmeal MarleRated 5 out of 5 starsFantastic sleep sack
We have been using this sleep sack since our baby was about 3 weeks old. He loved to have his arms free of a swaddle, so this offered us the ability to calm and relax him while also letting his arms be free. I have already repurchased multiples of this in a bigger size, and plan to keep using this as our baby grows.
