Anael I wanted ta let ya know what I know about flannel v. fleece. At one point #1 DSon thought he wanted ta be a fireman & took a 3 month course ta be one. He said that babies need ta wrapped well & only in 100% natural fibers. If there is a fire fleece & other man made fabrics will melt to the skin o' the babies. Older children & adults can git those fabrics off if there is a fire. Flannel is 100% cotton.
