Pam, This is probably a very late answer, but I'm al little behind in my reading lately. I seem to remember some discussion about lactoferrin interference with iron supplementation. Meaning - additional iron given to baby does not allow baby to use the naturally appearring iron in mom's milk as well as he might without the supplementation. In effect baby would get LESS usable iron. So this would seem to be an important point. Is this correct those of you who are more knowledgeable about the technical stuff? Lisa A LLLL who is also waiting for those exam results!
