My son is 5 months old and has been in the 95th percentile for head size since birth and its crazy/frustrating how quickly he has outgrown hats. Most of the ones we had came with outfits so they were pretty basic, just don't understand why theres not much give to the material. This one is stylish, price is right, and seems like it will fit him for a long time. I will probably buy this in additional colors. Love it.
