Love this hat! My little girl is 4 months old and It’s perfect! It looks a little big or like she has room to grow into-will work for years to come but stays on amazing! Works great for out on the boat and windy days. And not to mention it’s sooooo cute!!! We’ve had so many compliments on the hat! It seems to be cool for her too- so many hats we’ve tried make her so hot on 90 degree days. This keeps sun and and doesn’t make her warmer.
