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.

- Lydia W.Verified Buyer7/10/26ReviewingSleep Sack 0.2 TOG DaisiesRated 5 out of 5 starsAmazing
Brilliant for baby during heatwave. Can unzip and leave legs out when really hot. Really soft and fits well with enough space for growing.
So glad I got it with these UK heatwaves
- Mitali S.Verified Buyer7/9/26ReviewingSleep Sack 0.2 TOG WillowRated 5 out of 5 starsPerfect for a warm baby!
This sleep sack is the perfect size and weight for our 7 month old. He gets warm quickly, so this is a great weight for the summer.
- Stephany T.Verified Buyer7/7/26ReviewingSleep Sack 1.0 TOG DaydreamRated 5 out of 5 starsGreat!
The material is just heavy enough for our baby to feel cozy without overheating. We live in Florida so it’s very hot but have the AC on all the time, I’d say these sleep sacks TOG 1 are great for nighttime! We us 0.5 during daytime naps
