Yael, coco also has allergies. We love chicken risotto here (just rice, chick mince, and some vegies ... zuchinni, mushrooms...whatever. I didn't use stock to begin, but do now. I also tried her on egg yolk last week.....hives. So maybe avoid that (she has excma and as far as I know it's externally caused but dairy, egg and some other things make it worse, including weet bix. But saying that, bread doesn't (we go wholemeal or multigrain). I also feed her mince and we tried a lamb cutlet the other day HUGE hit.
I give lots of fruit, don't worry about sweet tooth...they will learn about lollies later, and you will wish he ate more fruit, so I say stick with it!!
I also give coco baked beans, salt reduced, with vegies. She loves it. We also have salmon (tinned ).
