My ds is also allergic to oatmeal. He also has problems with corn (but I knew he would as he had allergic symptoms when I ate corn right from the start). We have not had problems with any other foods. What we did after introducing solids was to prepare him a bowl of food and gave him a spoon. He was happy to imitate us eating, but got very little if any into his mouth. This satisfied his desire to eat when we were eating but delayed him getting any real solids until he was ready for finger foods. (about 8 or 9 months) when I started giving him rice puffs and steamed chunks of fruit. I felt better about this as I didn't want to risk any other food allergies. I also waited a full week between introducing new foods and watched him very carefully after anything new had been eaten. I also followed the latest recommeded age to introduce things (no wheat, soy, seeds until after a year, no berries, nuts, until at least 18 months etc-we don't do dairy so that wasn't a concern). I also laid off the grain after his reaction to oatmeal, instead I went with sweet potato, avacado, bananas, etc.
