I purchased this hat for my 10-month-old baby in size 12 months. The hat is super cute, warm, and soft. Although I've only washed it once at this point, the fur remains soft and aesthetically pleasing. Given that my baby is technically too young to safely wear a scarf, I am delighted that this hat has ear flaps and velcro to close around her chin and keep her warm. Although other reviewers have commented on it being undersized, I haven't noticed a problem. My baby is 10 months and 50th to 75th percentile in head circumference and the 12 month old hat fits her perfectly. It is comfortably snug.
