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.

Sleep Sack 1.0 TOG Daisies
Rated 5 out of 5 stars
Sweet Dreams
I love the variety of sleep sacks for my girl. She's quite tall for her age (10 months) and I find the ergopouch has plenty of room for her. I have the 0.5, 1.0 and 3.0 tog sleep sacks. Very comfortable with plenty of movement for her to crawl and even pull to stand as part of her wind down before sleep haha.

Sleep Sack 1.0 TOG Sage

Incredible! My six month old is long like 30 inches long and this is snug around her torso but nice and long for her legs! I love it! Also the fit around the neck and arms is way better than the halo
