For baby quilts I often use flannel for my batting. It gives enough body to be used more as a blanket. I often use flannel on the outside of the quilt as well. I watch for it to go on sale at JoAnn's. I don't care for much of JoAnn's fabrics quality wise but their snuggle flannel holds up really well. I've made burp cloths from it and they get a lot of washings so after that I trusted it enough for a quilt.
