Lisa, has Liam had the bloods taken for gluten intolerance yet? I'm pretty sure he needs to be on a normal diet otherwise the test results may not be accurate?
Anyway, this is what Nathan eats on a day-to-day basis, I try and include some protein at every meal as it's a longer lasting energy. Also, Nathan's not a big meat eater (until the last month or so) and surprisingly he was only slightly low in iron and my doctor didn't think it necessary to give him a special supplement, but I do give him a kids multi every day:
Breakfast: rice cereal with soy milk and a banana
Snack: corn thin wafer thing with peanut butter on half and a vegetable spread which is high in B vitamins on the other half (not marmite it has gluten), apple, carrot sticks, a couple of rice crackers, cheese, luncheon meat (gluten free)
Lunch (he pretty much has yoghurt, flaxseed oil and fruit with all lunches):
Scrambled egg with chopped up spinach, fresh herbs
Baked beans
Gluten free bread with grilled cheese
Avocado, tomato, carrot etc
Sometimes I give dinner for lunch because I was finding him more receptive to eating so would cook up beef or chicken chip type things (gluten free) with veges
Snack: same as above
Dinner: Fresh baked fish, oven fries (non gluten), salad
Sausage (gluten free) which is about 70% meat, with brocolli, plain potato, pumpkin
Chicken and mushroom casserole with rice
Roast chicken meal with veges
Vegetarian casserole with beans, potato, pumpkin etc, rice
Lazy dinner - red kidney beans and just a pick of other things from the fridge to balance it out
HTH
