I have so far really liked this hat. I have a 7mo. boy and bought the 12-24mo. size, and it fits him great (I wanted room to grow too). The string that holds it to his head is great for when it's windy and he moves around a lot. It's cute, and when we're outside in the sun it blocks the sun from his face very well. We went to a baseball game in Florida this weekend, and he was outside for two hours and no sunburn! (though we did put sunblock on his face as well).
