My 19mo son had a blood test the other day (unrelated illness, nothing wrong thankfully) but it turns out that he has low iron. Now, I BF on-demand, as I did with his 4y.o. sister, and I have read that breast milk is the highest and most easily absorbed form of iron that a baby can get, so I thought I was doing right by him. I also take supplemental iron for myself, which is supposed to pass into my milk too, giving it an extra iron boost. I am lucky also that my son eats a well-balanced healthy diet, so how can his iron levels be low? Is it true, as my doctor said, that breast milk hinders the absorption of iron in toddlers? He is generally in favor of BF and in other circumstances wouldn't encourage weaning, but in this case he said I should think about stopping soon. He also prescribed iron supplements for a couple of months to see if that helps. Has any one else encountered this problem?
