LOL, acrobatic breastfeeding!
Some moms have success using nursing necklaces. Brightly colored baby safe necklaces for baby to play with while breastfeeding.
Some moms will sing or play with the baby to keep her attention.
Some moms have success taking the baby off anytime she gets acrobatic and only allowing the baby to stay on the breast when more calm.
Good luck, I'm sure you'll get lots more ideas.
