Just a quick review to add that I adore these sleepers, however, I completely agree that these are best fitted for LONG and LEAN babies. They are slim fitting, so if you have a little chunky monkey, I would pass on these. My little guy is off the charts in length (29" at 4 months), but he is average weight (83% percentile, even for his height). They are 100% quality cotton, adorable, great low-key colors - but if my son were any heavier, the buttons would be poppin' open! I especially loved the gown version of this sleeper - it was my favorite thing to put Logan in when he was newborn. THOSE are a bit more forgiving
