I think the DHA and other labels like this on baby food/formula is a total marketing ploy - there, I said it - LOL! Call your pediatrician, but according to this article the AAP is not taking a stance on it and that leaves it up to your pediatrician's discretion. Also note none of these claims have not been supported by the FDA. Not that that should be a deal breaker, just food for thought. Good luck!!
