I think nursing manners would make your life easier. She can learn patience and not to pinch you. She isn't going to like it when you walk away from her (mine screamed at me) but she will catch on REAL quickly.
At one year, I started just nursing DD before bed and when she woke up for the morning (she still woke up at night at that point but stopped when se realized she wasn't going to nurse). I closed the milk parlor every other part of the day. Meaning tight shirts tucked in and no options to pull boob out. Yes, it sucks for everyone. But she will learn to cope. Not every one agrees. But limiting supply and requiring nursing manners made nursing life MUCH more enjoyable.
