Review on UV Protection Sun Hat For Kids - LANGZHEN Toddler Boys Girls Wide Brim Summer Play Cotton Bucket Hat With Chin Strap by Mark Williams

Ordered the XS 3m-6m for my 6 month old son, who is on the small side (10%). The hat is still a little big and slides around on his head, but it isn't so deep that it covers his eyes when it's on his head correctly. There is room to grow which I had hoped would be the case so if your baby's head is normal/small and you're trying to decide between sizes I'd probably opt for the smaller size. I also like the buttons on either side that I can use to flip up the sides if it's too floppy for him.
