Hey, I know you're busy, so I'll keep it short. Nursed for 4 years myself, 3 kiddos and all the breastfeeding issues you can imagine! Try repositioning you, not her, until she gets this out of her system. You don't want scabs on those precious boobies! Nurse in the most unusual positions so she has no chance to push up. Her on the bed, you over the top. Whatever you can think of! Good luck!!!
Oh yeah, as irritating as this sounds, it IS just a phase! LOL. Again, goooooood luck!
