I see you are still fighting it! I really like advice given by Aunty. You switched formula, baby lotion, but have you looked into washing your baby clothes in something else? And especially being carefull about fabric softeners? The allergen may be also in the materials baby clothes are made of. There are organic cotton clothes aout there!!! Is your baby nursery freshly painted or wallpapered? Just guessing here! But definitly look into washing these clothes with something else.
