First off, good for you to write that last sentence!!!
You should or can pump just a small amount off when you are in such pain. Within a few days, your supply should go down a bit as it's getting used to not being nursed, etc.
Good luck!
Congratulation for breastfeeding, no matter how long you did it! I believe even a short period of time helps you and your baby.
Now that you are done, though, try pumping (just enough to relieve discomfort but still leave the tanks full but not painfully so), ice packs applied to the area help some folks, Tylenol helps some, too. It's a supply and demand situation, it just takes a few days for your breasts to adjust to the changed in demand.
It may also help to have someone else give baby it's bottle until your breasts dry up some as for many people just thinking of feeding the baby gets the milk factory going.
PS: Try not to worry about what other people think. I'm sure you wouldn't agree with all their opinions or choices either. :-)
I quit by cutting out 1 feeling at a time, but you're right, it can be very painful. I put ice packs on at night and it was gone in a couple of days.
Check with a lactation consultant. Mine told me that a tincture of sage is often used to dry up milk. I don't know how to make a tincture, but I imagine making something yummy with lots of sage in it might do the trick! Good luck!
