To comply with safety requirements, our Cocoon Swaddle Sacks 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.

Rated 4 out of 5 stars
So cosy!
Love the quality of this one. Only feedback is that when arms are out it cuts into bubs armpits a little as he’s quite long
