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.

My baby is 14 months old, I bought the TOG 3.5 size for 2-4 year olds and it's been great on these days when the temperature drops in the morning; she stays safe, warm and comfortable.

Our LO hates being wrapped up. Resisted swaddling with all her little might. We've tried every swaddle and sleep sack we can find and the ergoPouches are the only ones she doesn't actively fight. The shape allows her to move around and feel less constrained while keeping her warm and safe.
We started with the transition one to help with her startle reflex (very helpful that it comes in a 0-3m size!) and once she outgrew it, moved to the standard sacks. They're both awesome!
