Your daughter is probably too young to have worn this certain kind of pajama or nightgown that just seems to wash and dry badly getting wrinkly and staticy. I have experienced it in Barbie nightgowns (the kind that come with the matching doll nightgown attached), Minnie Mouse nightgowns from Disney World and some other PJs. I think it has something to do with the flame retardancy. I have had this problem with some PJs regardless of the price of the sleepwear.
