I read plenty of review so went in to this knowing that the hat would likely be big for it's size so I'm not complaining about that. I bought a pink one in toddler size for my 3 year old girl. It fits her with PLENTY of room to grow. I think it just about fit my head. I'd rather have larger though than too small so I opted to risk the larger size. I also got the sage color in infant for #2, who will be born in a few weeks. That one actaully could fit my three year old's head now so it might be huge on him when winter hits but again, I figure if it doesn't fit this year it will in the future.
