Love this sleeper. The zipper is very convenient, the color is flattering, and the style is smart looking. All of the Kushies outfits we have are very well made and stand up to many washings, so they're perfect for everyday.  Like one of the other reviewers, I wanted this outfit for trips to the pediatrician or other occasions where getting in and out of the outfit easily was a must.  I was happy to see that this sleeper is sized a little bigger than the Kushies onesies. Our 6 week old weighs 11 lbs and is "tall." He has already grown out of the 3 month size of the onesies but this sleeper in the 3 month size will still fit for at least a few more weeks.
