What exactly are your blood counts?
It is actually more dangerous to be pregnant with those issues than to be nursing. Nursing is more of a nutrition thing, and is the healthiest option for BOTH of you. You'd be amazed what stopping nursing can actually do to your system.
I had low blood counts during pregnancy (platelets were usually at 55K as opposed to the normal count of 150K + and ended up dropping to 27K). They went up to a still low 85K once she was born, and my blood counts were still low so I had to get B-12 injections and see my hemotolgist every other week. No one ever told me I needed to stop nursing. Basically, nursing and blood counts are not linked now that she is outside of you!
Best of luck to you--it can be scary, but rest assured your gift of nursing will not sacrifice your health.
