I have PA and I'm currently breastfeeding my 10 week old baby. I am having regular B12 injections and my levels are fine. I'm concerned about the antibodies I am passing to my daughter. If I have this straight, I have antibodies that destroy the cells in my stomach required to absorb vitamin B12. Through breastfeeding you pass antibodies to your baby, could I be passing antibodies that are destroying cells in my babies stomach? Could this mean she can not absorb B12 from my breastmilk. Is anyone able to advised?
