Aw, is she worried he will ruin them somehow? Like worried her will stain them up? Like maybe she is keeping them for "nice" and putting them away? Maybe you couldtell her they are just to love not keep forever?
This is my thought, that she wants him to have it "nice" for later. But let her know, it is in using it that it will be very dear to him. And yes let her know you can make another that she can put away, but let him have at the love blanket.
