thankyou for the replies
yes, I agree Melissa, and especially since there seems to be no one solution for eczema...everyone is completely different. His eczema is certainly aggravated by stress, and stress/tiredness appear to bring on the need to scratch which of course makes everything worse.
A the moment they are using wet bandage wrapping to try and soothe things, and that seems to be helping. He helps as much as he can, and tells his parents when he wants to scratch..at two years old!
Rice bran oil seems to be one that is coming up as being used in salicylate free creams, so we may give that a go...
