much as we would like to help, we, and probably most general-interest food sources, are reluctant to respond to your question without knowing very specifically what the child can and can’t eat. And even then, it might be that a professional dietician is the most practical source for guidance.

A former staff member, though, found great help for one of her children in the book Healthy Cooking for Kids (Canada, UK). Whether it is relevant to the needs of your friend’s child, we don't know.
