I can't help but think what an overly cautious, litigious society we have become. Of course cotton is flammable. So is the batting. But think back over the hundreds of years children have slept under quilts made of cotton or whatever was around. Did their parents need warning labels? Of course not. In a society where we need warnings on a cup of hot coffee telling us it is hot I'm not surprised that anyone would be alarmed at the "not intended for sleepwear" warning. Personally, I'd be more concerned about the chemicals in the fabrics that ARE intended for sleepwear.
