hi juliette

my ds had problems with dairy. you could try eliminating dairy from your diet and try soy do it for around a week and if it clears up then introduce dairy again if it flairs up you will know that it's the dairy. this is called a challenge test or something which we had to do with my ds when he was around 8mths old (he was allergic to dairy, nut, egg, dog, cat, feathers, dust and grass - he is allergy free from most now except the nut)

you could ask about a great cream called Elidel it is expensive (around $40 a little tube) and only available on prescription but the great thing about it, it is not a steroid cream. i also use a product called natural instincts for the bath (if you read qv still has some chemicals in it) the stuff i use is all natural and smells devine. also moisturise heaps with the sorbelen and maybe not to many baths at least hannah doesn't really need one every day right now.

good luck
