just so you know, cheerios contain wheat. you would be better going with puffed rice, plain not sugar coated (arrowhead mills makes a good one). you can find it in your health food store probably. be sure to read the ingredients carefully. keep in mind that if you want to avoid wheat that means bread, corn tortillas (most have flour in them), most cereals, pasta (deboles makes a rice pasta), cookies, anything with flour. you will have to learn what to look for on labels.
you can start introducing lots of fruits and veggies though. by the time you get through most of them your lo should be old enough to start trying dairy, soy, wheat, and the rest. here are a few things that we steamed and pureed. sweet potato, spinace, potato, kale, beet greens, carrots, turnip, watercress, rutabaga, all squashes one at a time, papaya, mango, all berries except strawberries, apples, avacado, aprocit (his fave!). you can check out ruth yarows book "supper baby foods". she has a page that breaks down what age they can have what foods. she also lists a good variety of foods. look in your library first so you can decide if you like it enough to buy it.
if you get jar food you must read the label every time you buy a jar. i didn't and one company changed the formula of our favorite and he start to get sick again before i figured it out. (they added barley!)
with his skin you can try cediphil wash and lotion. it is really good for eczema!
