My daughter used this during the winter when she was 0-1 years old. It's size 70-90, so I think it can be used for a long time. It's a poncho type, so it was easy to put on the baby, and it's very cute. - Color: White - Size: 70-90 - Weight range: 9-13kg - Outer material: 100% polyester - Lining material: 100% polyester - Hood lining: 65% polyester, 35% cotton
