I first saw the name "Aidan", but I didn't like the "A", so I changed it to an "E". In relation to food allergies, none of my kids, or my husbands family have any food allergies. My neice and nephew suffer bad eczema, but they didn't start solids until they were nearly 5 months. My baby also suffers from eczema, but he had that at 3 weeks of age - before he started on solids, so I don't think food has any thing to do with it. I wouldn't give anything else other then the rice cereal until he is at least 4 months of age, but rice is so mild it can't hurt him. Just give him a little cereal mixed with his milk, one feed a day. If he gets contipated, don't give him another feed for a couple of days. He should be able to tolerate it though, as he is almost 4 months. You won't know if you don't try.
