My friend went through this recently. She just had to pump after each feeding to keep from getting engorged. She stored a lot of milk in the freezer.
From what I've read, the more you pump the more you produce. Maybe you should stop pumping. If it gets painful, go in the shower and hand express. Pumping and feeding is making your body believe your baby needs all that milk at once.
I agree that pumping will only tell your body you need all of that milk. I would ask a lactation consultant for advice, or your doctor. I've heard that cold cabbage leaves help with engorgement.
I agree with the last 2 comments. If you nurse and pump you trick your body into thinking you need that much milk. Unfortunately you just need to stick it out a few days. Your body will figure out how much it needs to produce to satisfy your baby and the engorgement/overactive letdown will reduce. I let baby nurse for a second to get the flow going and then take him off the breast and let some of the milk come out on its own into a receiving blanket. Messy yes but lets a little of the pressure off. Stick with it. It gets easier!
Yes, the more U pump the more Ur body will produce. Try to limit the amount u are pumping unless u are going to back to work and u are working on building Ur frozen milk supply. If it's uncomfortable try doing warm compresses on Ur boobs after the baby nurses, this will help w the pain of engorgement. And yes it's gets easier the longer you nurse and once Ur body gets used to the amount of milk the baby needs.
Thank You everyone!! Definetly going to try all of this!
