I don't know if I can help much, just offer some empathy - I can't bear twiddling, so never allowed it BUT that never stopped *every* nursing session being a wrestling match. He would also just poke, scratch, and pinch me everywhere...I would try holding his hand or deflecting it, and I also would stop nursing him as a natural consequence, which resulted in angry crying and tantrums [he's pretty strong-willed - never gives up]. It is no fun.
Have you tried giving her hand something else to play with, a blanket or toy - or even another part of your body, your thumb or something? And/or expressing to her that it hurts? "Ow, that hurts mommy! Here is your nursy toy instead."
