Raina, I just can't see how it was wrong for you to encourage your daughter not to pinch you. If it wasn't about nursing at all-- she was just coming up to you and pinching you, would you have allowed it or discouraged it? I hope you wouldn't let her just come up and pinch you!
Reuben was a pincher too, and I quite emphatically discouraged him from pinching me. Any time his latch is sloppy, I talk to him... Hey dude, you're hurting me, do you want to snuggle and read a book or fix your latch? CLW-- does that really mean bearing pain? There are lots of appropriate times to redirect our kids and set limits for them. Well, at least that's our belief at our house.
As for not having another baby... we have left that totally to G-d to decide. We neither TTC nor TTA. We take them as they come. I do admit that I appreciate LAM!
My first 3 all weaned early, my first 4 babies came in 5 years. My next 3 nursed and my last 5 years have only seen 2 more babies. Have to admit that LAM is a nice side benefit of nursing.
