Felt awful returning this incredibly adorable hat in a style and pattern I love, but it was sooo small, it didn't have a prayer of fitting my boy.  Bought the 2T size when he was under 2, and although he has a big head, admittedly, I guess I thought baby & toddler hats would run large, since baby & toddler heads tend to run large.  :)  No such luck, so back it went.  Bummer.
