Size Guide
Cocoon Swaddle Bag
Please use your child's weight to find the most appropriate and safe size for them. To comply with safety requirements, our Cocoon Swaddle Bags have a firm fit around the neck, shoulder and chest area to prevent your little one from slipping inside. You should be able to put 2 fingers inside the neck opening for the correct fit. Please do not size up to the next size until your child meets the weight requirement, for safety reasons.

- Tarek S.Verified Buyer2 weeks agoReviewingCocoon Swaddle Bag 3.5 TOG DaisiesRated 1 out of 5 starsNever received it
I ordered this item express delivery and added extra protection, but I never received it. It’s been two weeks since I ordered it. And I haven’t been refunded. Very disappointed. Waste of money.

This sleep sack is perfect! It's super cozy without overheating and fits snuggly around the arms so there isn't a bunch of extra fabric. My only complaint is that she grew out of it quickly! But that's a her problem :)

Warm, cosy, and with the possibility of arms swaddled or out. Bub is sleeping really well now.
