Is one occurrance of blood in the pump necessarily a major concern? I have heard that on occasion a capillary may break resulting in a small amount of blood. It doesn't take much to make the millk look quite red. I wonder how many times this happens when baby is nursing directly from the breast and we never see it. Of course pumping technique and strength can be a reason for blood, but in some cases it may be very benign.
