Grandbaby loves this hat and she is pretty as a picture wearing it. We love that it is 50spf and the wide brim allows for ample shading of her face and protection of her ears, neck and shoulders. The sizing is about right - We got her the medium and she is at 6 months. I was initially concerned it would be too big since (by age) she is on the low end of the size group for medium (6m-12m) -- but it fits here well now and since the head doesn't grow as fast as everything else will, I believe she'll enjoy it for many more months. You can't go wrong with this purchase!
