The ice cream patterned romper is for 3-6 months, and the other two are size 6-12 months! I am selling these because my child has outgrown them. I don't see any noticeable stains, but please understand that I may have overlooked something as I am a private seller. These have been stored at home, so please consider purchasing only if you understand that they are used items. When shipping, I will fold them to make them as compact as possible, so please be aware of this beforehand.
