In my haste to order an outfit my 5 month old son could wear for his baptism, I purchased this using my Prime membership so it would arrive in two days.  I should have read the reviews first!  As previous reviewers mentioned, the 6-12 month size was much too small for my 5 month old who wears 6-12 month clothing in just about every brand imaginable.  The "top" portion fit well, but the legs barely went past his knees and the lack of middle button on the rise meant that his diaper stuck out of the jumpsuit. On the plus side, the jumpsuit was really cute and the cabled cotton was soft.  Please add some length to the legs and a middle button!!!
