The size of the baby sleeping bag is approximately from 6 months old until 14 months old. The length of the baby sleeping bag is 80 cm (31,5 in). Use breathable materials for the sleeping bag like cotton and wool. I made my baby sleeping bag from two layers of cotton and I used an old sleeping bag for the lining. The zipper is 30 cm (12 in) long. Use an open-ended zippers and placed it upside down, to prevent the sleeping bag to be zipped open to easily.
