If this warning has to be on your child's clothing, you shouldn't have kids. Shouldn't you just know to keep fire away from your kids whether or not their clothes are flame resistant or not?
Oh good the clothes are flame resistant, now our kids can play with fire... Uh, NO.
Clothes flame resistant.... check
baby is still not flame resistant.
Baby can't play with matches.
Oh but the clothes are flame resistant
baby can play with matches
Haha a co-worker and I laughed about this for a while at work when I found this tag on the kids' pajamas.
