Can breastfeeding make you anaemic?

All that I've heard about breastfeeding are positive things. Anaemia would affect breastfeeding instead of the other way round, I think. NOT breastfeeding actually can cause you to be anaemic. If you don’t breastfeed full time for the first 6 months after you give birth, you will probably begin menstruating during that time. And, since menstruating uses up about twice as much iron as breastfeeding does, you will have a greater risk of iron deficiency. If a person is experiencing anaemia or have anaemic symptoms post partum, it could also be due to other reasons like having lost large amounts of blood during delivery. It is generally estimated that half of the anaemia cases in pregnancy are related to iron deficiency. Moreover, taking care of a newborn is a demanding job. Delivery leaves most mothers feeling very tired, but if you are anaemic, you may feel much more exhausted—just when your infant needs so much attention and care. Maternal iron-deficiency anaemia has also been shown to be strongly associated with depression, stress and cognitive function in the post partum period. http://www.anemiainwomen.com/html/risk.htm
