My daughter is 3 1/2 months old. I have never ever had bleeding nipples. I have to work really hard to get enough milk for her during the day, so I have to pump 3x at work. It is really tough. I have been getting between 4 - 6 oz during my first morning pump and then 2 - 3 oz at the other 2. Well this morning I got about 3 1/2 oz and there was a red tint to the milk on the outer part of the flange. I think my nipple was bleeding. I don't see any area of blood on the nipple. There is a red section on the bottom. What can I do? What do I do with the milk? I only have 8 oz frozen as I have never over produced. The milk in the bottle looked ok, but I am not sure if it got any blood in it or not. What do I do about my later pumpings? I am kind of freeking out if you can't tell.
