This wearable blanket was used by my daughter from around the age of 2. It was very useful during this cold season, as it could be worn over pajamas after a bath, first thing in the morning, or for a quick nap, and it covered her feet. It has no sleeves, so it doesn't get dirty easily, and the material dries quickly after washing. I think she used it until she was about 5 years old. Even as she grew, she could still use it as a vest. The length is 70 cm.
