Size Guide
Sleeping Bag (formerly Jersey Sleeping Bag)
Our Sleeping Bag is a baby and toddler sleeping bag designed for arms-out sleepers (usually from around 3 months of age). The Sleeping Bag has a slim-fit, stretchy design similar to that of a swaddle and is recommended as baby's 'first sleeping bag' after the swaddling phase is over. Please use your child's weight and height to find the most appropriate and safe size for them. A sleeping bag should be well fitted around the neck and the armholes to avoid your baby slipping through. It should also be bell shaped in the bottom to allow for easy leg movement. Please do not size up to the next size until your child meets the weight requirement, for safety reasons.| ergoPouch size | 3-12M | 8-24M | 2-4Y |

So cosy, breathable materials, so soft. My baby boy loves wearing these to bed and sleeps all night. I have a collection building and couldn't be happier with the quality and designs.

We have had every size of these sleepsacks and this is the only brand I will use. I have a very active 2 year old and these sleepsacks are the only thing that have kept him in a crib. He loves putting them on at night and they keep him nice and snug. He is able to unzip them, but will not unless we are getting him out of bed. They are made of high quality material and are 100% worth the price.
