I'm probably going to be disliked for saying this, but when my babies were little, I laid them on the few quilts I had, but other than that, didn't use them to swaddle the child. Quilts are just too bulky to swaddle a baby, or tuck them in a car seat. I used fleece, flannel, and crocheted blankets to swaddle them and tuck them in car seats. Some of the quilts I received ended up being wall hangings. Since I can't help with batting weight, I suggest using fleece for the backing as it is softer against a baby's skin.
