Sorry I don't have the answers you're seeking, but I did realize something. Have watched many quilt shows that have shown baby quilts or have commented on how a certain pattern could also be used as a baby quilt and no one has mentioned flame retardant material or batting. Shows such as Fons & Porter, Sewing with Nancy, Kaye Woods etc. Seems if this was very common it would be discussed on shows like this. I could have missed it I guess.
