Hi E.,
I have a few questions for you. First, how did they test him for the anemia this last time? Was it a finger prick test? They are not always accurate, so I wouldn't worry if he is that close to normal. The test that most accurately assesses iron levels is serum ferretin, so if you are worried I would have that tested.
When my clients have this issue, I always ask the parents if the children show signs of anemia at all, if they are developing normally, etc. If they are, I do not get too concerned. Anemia makes you tired.
Was your child breast fed? Some of the numbers for anemia were set based on levels of babies getting iron-enriched formula, which yields higher numbers but not always better outcomes, so that is a possible issue here as well.
I think the iron-rich foods are the best way, with meat being probably the most absorbable source. You could also consider a less-bad tasting supplement. I would be happy to help you identify one, if it is deemed appropriate. As other moms on this site have mentioned, too much iron is as dangerous as not enough, so we always want to be cautious about supplementing iron.
Let me know if you have any further questions that I can help you with.
Best,
E. Bender, NC, CHN
