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 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 |

- Anne V.Verified Buyer4 minutes agoReviewingSleeping Bag 3.5 TOG DaisiesRated 5 out of 5 starsVery soft & warm, and a beautiful print
This sleepingbag is so nice and warm, and soft. It’s very easy to put the little bay arms through the sleeves.
I really recommend!!
- Victoria M.Verified BuyerYesterdayReviewingSleeping Bag 2.5 TOG WillowRated 5 out of 5 starsBaby loves it
I needed a sleep slack to replace his favorite which didn’t come in a bigger size (he got too tall). He loves this one and the switch was super easy! It’s so soft and nice and thick, he’s a happy baby.
- MeganVerified Buyer3 days agoReviewingSleeping Bag 3.5 TOG Oatmeal MarleRated 5 out of 5 starsSleeps better
My baby is sleeping better since getting this sleeping bag. I think he was getting cold in the middle of the night and this is warmer, and crucially, covers his arms. I’d recommend!
