Richard,
I would like to say that from what I have read on this post, in medical
journals, heard in seminars and by word of mouth that a multivitamin
would be a good idea for you 2 and 1/2 year old. I understand that with
celiac's disease that one does not probably digest the B vitamins and is
therefore deficient on them.
However, I would also like to add that you pediatrician and/or general
practioner are always the best place to start for any such "medical
information".
