"Jenny has made a real impact from the bench when coming on so she deserves a chance to start against France," explained Wales Women's head coach Rhys Edwards.
"Nia is our most effective forward at the moment so we've put her back in the second row so Sioned can come back into the back row. It's all about getting the balance right in the back five of the pack at the moment. This is the third time we've made changes in that area so hopefully we've got the balance right.
"The backs go out against France knowing they have to finish off moves which is something we haven't done so far in the campaign," he added.
Wales have suffered narrow losses to Italy and Ireland in the opening two games and Edwards is fully aware of the size of the challenge which awaits them on Sunday.
"France are quite a formidable outfit at the moment. They have to be one of the best sides in the world. They recently beat England comfortably. We will have to be on top of our own game, stopping them at source so they don't have a platform to work from if we are to have any chance of claiming our first win of the campaign," he added.
