I bought this hat for my 3 year old daughter, loved it so much I purchased a beige one for my 18 month old son. It's by no means too big, it fits perfectly (we are a family of big noggins though).My daughter (3 year old) can take the hat off herself, but she knows to leave it on when outside. My son hasn't figured out how to take it off yet (18mth).I love the fact the neck strap will automatically undo if a certain amount of pressure pulls upon it (preventing strangulation) and the very wide brim.I'm buying another two so I can keep one at pre-school and have one each at home.I would recommend this style of hat.
