I don't know what the other people who didn't like this product were complaining about.  Yes, they do run big (my 4 month old should have been in 3-6 months instead of the 6-9 months that I ordered).  In other sleepers she is in 6 months BUT the quality is great! They are actually a light ribbed cotton, which is perfect for me since we live in Oklahoma.  The patters are also super cute.
I would definetly buy more if they had other patters for girls or unisex ones.  Don't let the other views stop you from getting these:D
