This is a size M swaddle. I purchased it new in October 2025 because I needed a larger size, but I only used it about 5 times because my baby started rolling over. I used it on a standard-sized 4-month-old baby, and the width was just right, but there was a lot of extra length. The size is set to 80 cm, but it's a size M (3-6 months). Original price: 2799 yen #swaddle #sleeper #baby #coperta
