DS is growing out of his pajamas fast. I have a couple in larger sizes that people gave us as gifts, but they're both flame-resistant. I've read a little about the chemicals in those... no idea what would get them out though. Does anyone know if a couple of good washings would help? Or is it better to stuff them in the back of the closet and never use them?

I guess it's a bit silly worrying about pajamas when the flame retardants are in couches and stuff, but I'd rather not have them in the kid's clothes anyway!
