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.

Great purchase would definitely recommend forking out on a 2.5 tog. You can get away with 1 tog at kmart or target but you van definitely feel the difference in something a bit thicker. Plus they wash much better.
- Charlotte A.Verified Buyer4/1/26ReviewingSleep Sack 2.5 TOG DaisiesRated 1 out of 5 starsDisappointed for the price
Followed the size guide and bought a set of sleep sacks for my daughter, washed and got them ready to use and they just don’t fit such a large age range. They bunch up and leave her uncomfortable and restless. Smaller sizes work, and we liked the zip blanket but these sleep sacks aren’t useable for such a large age range. An 8 month old and a 2 year old aren’t comparable.
