I got this hat for my 2 month old daughter.  She has a small head.  This hat fits her fine!  I don't know what people are complaining about.  The adjustment is not made to go all the way around the head as one reviewer must have thought, because she complained that the string to tighten was sewn in to the stitching.  It's MEANT to be that way!  When you tighten the hat, only the back half tightens, giving it an almost bonnet like look.  I think it's darling.  It's not too big for my daughter at all.  The brim of the hat is large, but that is where you get the sun protection.  I love the tie, and I had no problem keeping this on her head even in windy Colorado.  I was surprised when I got the hat and saw it is SPF50!  And as for the toggle being in the way when you might lay baby down, I rarely lay my baby down anywhere, much less when we are outside.  She's either in my arms, or in the sling, so this wasn't an issue for me at all.  I really can recommend this hat! I am going to order her another one in the larger size for when she outgrows this one.  And thank you for the great price too!  Some sun hats are over $20, so I really appreciate the affordable price on such a great hat.
