After losing 3 pairs of mittens in about 2 weeks, I went for the string kind, and picked Zutano as everything else I have from them is great! They are generously sized on my 20 month old, so I'd say they would be HUGE on a 6 month old, but they work for us! I like that they don't have thumbs because I couldn't get her fingers in thumbholes anyway! Navy is a nice color, unisex, matches all her coats, and most importantly hides dirt!
