Elaine, like you said, you had a nap and you have figured out what you are going to do.
I really think your son treasures the quilt because if he didn't, I think he would have tossed it.
So, get the quilt, put the bandaids on it. That's what we moms do when our kids have "boo-boo's", and patch it up. Maybe put OUCH or something on some of the patches,,,just for fun.
Then maybe he'll be a little more caring when he decides to leave the quilt with a dog/pup again.
