Julie, I haven't seen too many babies that are strickly on br milk past 6 mo -- would that I would see a lot on ANY br milk past 6 mo -- but that wasn't your question. Re iron levels: The one mom who's baby was refusing any and all solid foods (was a psych issue, which was resolved) at 12 months did have a low hgb, but not dangerously so. What about checking hgb with a fingerstick periodically, and if necessary, give iron supplements, and, of course, continuing to offer solid foods if appropriate in this situation? I bet our Martha, queen of trivia would know some definitive answers and references, however. Right Martha? Jan B.
