What foods is he eating- have you tried a rotation diet, food journally? What probiotics -include ingredients or links to ingredients if you can? Which supplements (again ingredients?)? What about environmental allergen exposures? Pets? Dust mites? I saw something about mold issues?
Allergens have a "bucket effect", when it is overflowing, then you have reactions. What about homemade formula? What primary foods is he consuming?
Primary allergens are dairy, soy, wheat/gluten, corn.
Kirkmans makes a hypoallergenic bifidum for infants. Here's a link to the Kirkman Labs hypoallergenic probiotic. http://www.kirkmanlabs.com/products/...0_Spec042.html
For baby, you want bifidum bacteria, predominantly.
I'd suggest making dairy-free water kefir. It is easy and delicious and will help baby's gut and you can let baby lick a bit of it off your finger. (That works for giving baby powdered probiotics too. )
Have you eliminated corn? Many mamas are intolerant of GMO-corn
. Corn is in EVERYTHING. Dairy exposure is everywhere. Here is a list of hidden diary: http://www.kellymom.com/store/handou...dden-dairy.pdf

What grains is he eating? Have you tried buckwheat, amaranth, quinoa? These seem to be more tolerated. Rice is a common food intolerance for many here after being on TED for any length of time.
What about magnesium, zinc, B6, B12, folate, selenium, vit C sources? Which fish oil? Does it have synthetic vit A added?
What are the ingredients in the steroid cream? Generally there is a rebound effect once a steroid is stopped, but the stimulus is not removed.
Are you feeding fruit alongside fats and meats? Many have had difficulty with deli meat- for instance having corn contamination. Fruit festers in the stomach, unless eaten separately. Zinc is critical for adequate stomach acid to adequately digest proteins. A tablespoon of cabbage juice will help similarly.
Have you tried any herbal infusions or bone broth for nutrients and minerals? Have you given baby coconut oil? Is coconut an issue? It is for many on the allergy forum, unfortunately. Sunflower oil, sesame oils are other culprits.
Egg yolks are very helpful for biotin and vit A. But, often the whites are an issue.
And I strongly recommend classical homeopathy!
