When I was buying jammies for DGS a few years ago I discovered that one of the firs things to do when you buy the flame retardent PJs is wash them. If you wash them a half a dozen times you have removed most of the flame retardent so why bother with it in the first place. I think it would be better to insist that you use only cotton in kids PJs then you can save the money spent on chemicals and water to wash out the chemicals.
