The Baby Star Wraps are designed for use with small babies, who would usually be using a car seat, travel system. The main idea of the Baby Star Wrap is to avoid all the faff of undressing and re-dressing. Once your baby can stand, it is much easier to remove a coat when getting in and out of a car seat, which is why these are designed from ages 0-10 months only.
Small - 0-4 months
Large - 4-10 months
