Good luck with your baby, you must be shattered. I have had to hand feed and it is incredibly draining. I've always used RC milk and never had a problem with it, I did with KMR when I tried that. Little babies are tougher than they look. You may find when Mum gets over the whole birth stress, she accepts her baby. You could try her again, to see if she accepts her, as long as you are there to ensure she can not hurt her. Even if she just cleans her for you, its a start.
Good luck
