I have ordered this sun glasses for my child at 5 month and it fit perfect for the summer but when I ordered the next size up 12-24month what I got was the same size i got when she was 5 month old! unless they expect my childs head to never have grown (my pediatric would get worried,...) sellers should understand 12-24 is not the same size as 0-12. buyers beware unless your child has a very narrow head 12-24 will not fit the child at 12 month. my rating for 0-12 would have been a 4 but since my 12-24 is 0 I'm giving it a 2 stars,...
