Our Sleep Sack is a baby and toddler sleeping bag designed for arms-out sleepers (usually from around 3 months of age). The Sleep Sack has a slim-fit, stretchy design similar to that of a swaddle and is recommended as baby's 'first sleep sack' 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 sleep sack 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.

I spent a long time looking for a warm sleep sack made of 100% cotton for my 7 month old. Shipping was quick and I chose the 3-12month size, knowing he would be swimming in the next size and hoping this will fit him through the cold months of winter. I just wish this was roomier in the hip section so he can splay out his legs more. It’s quite fitted throughout. I think he prefers how his legs feel in the Woolino which has much more room for froggy position.
