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.

Swaddle sleepsuit. Options for having arms in or out. I love it for my baby. Definitely the best quality I’ve seen. Baby sleeps very well in it for day and night sleep. We’ve had three of these now.
