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.

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.
