I've been on a baby quilt binge for the last couple of years, alas. I use W&N because that is what I have a roll of. That said, I am for any natural fiber..cotton; wool; silk; vs any poly or other synthetic fibers. I come from a fire background on several levels. Stick with natural fibers as they burn vs synthetic fibers of any sort as they melt to the skin. Natural is my go to for purchased or made bedding.
