Happened to see on the selvage of a fabric that I'm using for most of the backing on a quilt for my 2 1/2 grandson - it says to not use for children's sleepwear. I wondered then if cotton quilts for little ones are not a good idea and that maybe a cotton/poly blend would be better since it doesn't burn like all cotton. The quilt I'm making is all cotton (the front is complete) and I was thinking of getting a poly batting instead of cotton batting.

Am I worrying for nothing or is there something to this?
