Very difficult position to be in. I work in the pharmaceutical industry and have worked on many trials with children regarding allergies, inability to digest certain foods, yada yada. If you have a child that has a "problem" not just being fussy, it is usually because their body is not able to break down the foods, digest, and excrete them properly. The child learns this well before the parents even notice. I wouldn't recommend putting new foods in their diet in the middle of the ocean if they have a true issue with the food they are offered. (I had a picky eater and it was not hard to fish out. I also have a nephew that was a problem eater and it was an entirely different ball game. Not difficult to distinguish between the two). You may just find yourself asking for the same meal each night that your little one's tummy can tolerate. Bring some snacks that you know they will eat and of course their vitamins. It'll be OK. You may even find that they ask for new foods if they see other little ones eating them. But be sure to have your GI meds, Benadryl and what not in case they really can not tolerate the new food. Good luck. I hope it works out well.
