Size Guide
Cocoon Swaddle Bag
Please use your child's weight and height 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.

- Leia J. C.Verified Buyer11 hours agoReviewingCocoon Swaddle Bag 2.5 TOG Oatmeal MarleRated 4 out of 5 starsGreat quality. Runs small
My baby would never accept swaddling so we moved into these straight away. Had a size 000 and has fit him since week 2. These run on the smaller side so our little man has almost outgrown at 6 weeks old. Very expensive but will keep for next bubb

- AlanaVerified Buyer2 weeks agoReviewingCocoon Swaddle Bag 3.5 TOG DragonfliesRated 2 out of 5 stars3.5tog starts 1/3 way down
We bought the ore expensive warmest tog (3.5) for our 3 month old heading into winter, however the warmest/thickest part doesn't actually start until 1/3 the way down where his body is, and so his top half is still cold overnight with just the thinner layer. Disappointed as we have loved ergopouch over the years for all our babies.
