yes, improper cleaning can cause the same type of rash, so definitely check that first.
we know that isn't our problem for two reasons. first, ds's excessive gas is a huge sign for us. this kid has sooooo much gas, like 100 farts a day and he seems to be in pain. second, we EC so he's never in a wet or dirty diaper. ds#1 has it too and he's potty trained and we always clean him really well. plus, he has the allergic red cheek thing. we never did elim. with him unfortunately. wish we had because it's so much harder with a 4yo.
i detrmined wheat as a trigger (actually gluten - you're right) by elim. all gluten for 2 weeks then reintroducing it in each meal for one day. ds went from sleeping poorly after 5am (gas) before the elim. to sleeping great during, then poorly again when i reintroduced. he also was fussy that day and the next (usually really mellow) and had lots of gas. i actually got an excruciating headache myself so i know it affects me as well. my mom is allergic to gluten too and food allergies are generally passed along maternal lines.
read "is this your child?" it's a great resource in determining allergens.
i keep feeling like i nee to do the total elim. diet you describe xmasbaby7, but have no idea how i'd eat. have you runacross any websites with recipes/menu suggestions? also, if you reintroduce a new food every 4 days, wouldn't it seem like it would take years t get to every food? i still haven't figured that part out yet.
i've heard steel cut oats (irish oats) are okay but regular rolled oats are not. and rice is okay. there are some great rice tortillas/cheese/milks available so you can get your grains.
oh and carter insists on adding...
