I had a tough time with pumping as well. But I agree with what the one lady said about still nursing at night or in the morning. When you cut down the amount of milk you're producing... the nutrients and vitamins are concentrated... so even if your child isn't nursing off of you as much, the milk they get from you is even MORE nutritious!
If and when you do decide to quit nursing, I've heard to put raw cabbage leaves in your bra. When they smell like they're cooked, then switch them out. Doctor's recommend this too, so it isn't just an old wife's tale.
I weaned my son completely at 12 months... by that time he was drinking regular milk except for at night when I would nurse him. When I weaned him, I didn't have any problems or soreness. Since I weaned him slowly over a few months, I guess it wasn't as dramatic. So maybe you won't have any problems at all with your breasts being sore.
Hope this helps!
