When a baby resists solid food and/or has a family history of allergies or shows signs of severe and numerous food allergies, some mothers choose to rely on breast milk for the baby’s sole (if not “complete”) source of nutrition. Kellymom.com says: “Some babies are exclusively breastfed for a year (and occasionally up to two years) with no problems at all. In addition, some doctors recommend that babies with a high risk for allergies be exclusively breastfed for a year.” http://www.kellymom.com/nutrition/vitamins/iron.html

Kellymom also notes: “The current research indicates that a baby’s iron stores should last between six and twelve months, depending upon the baby.” Your comment implies that there is no iron in breast milk, although perhaps that is not what you intended. The good news on iron is that “up to 50% of the iron in human milk can be absorbed by the infant, as compared to 10% in cow’s milk, and 4% in iron-fortified formulas.” (LLL fact list). Some (many?) babies might need an additional source of iron (from solid food or vitamin supplements) at some point after 6 months, but not all babies will.

The points I hope to make are that parents need not worry quite as much as some seem to about getting solids into a baby, that breast milk continues to provide the bulk of nutrition, that it’s not always a good idea to push solid food when the baby resists or has allergies, and that there is anecdotal evidence (and perhaps more) that some babies thrive on breast milk alone for up to one year and even beyond.

Breastmilk does not provide complete nutrition for the second six months of life. I am all for full term breastfeeding (I am still feeding my 18 month old), but I think it is fair to point out that the energy gap between what a baby needs and what breastmilk can provide gets wider from about 6 months.

There are other important nutrients which are also needed – iron stores from birth run out at around six months, so it’s important for babies to get some iron from other foods.

While I think that many doctors are ill informed and try to bully us into pushing solids before the baby is really ready, it’s important for parents to be informed of the facts, so they can make an informed decision.

I hope that helps! If you get a chance, please let me know how the case turns out. I am rooting for your daughter and her baby.
