The Sleep Suit Bag should be fitted around the neck and the armholes to avoid your child slipping through. In 'legs' mode, there should be enough length at the end of the suit to allow your child to move their feet freely. 2.5 TOG and 3.5 TOG Sleep Suit Bags should not be used in a 5-point harness or car seat for safety reasons.

Weve only used it handful of times now and the stitching from sleeves are coming off. My toddler was fascinated by the thread and she was trying to break it. I have just found along with the other zip suits that we have bought - the quality has been average

It’s an amazing suit! If I could change one thing, it would be the sleeve length. They always seem to be too short. Even when I buy a larger size, the sleeves are still quite short. Other than that, it’s a fantastic product.
