Thanks for the replies...
At the moment it is dermatitis - i wonder if he will get excema?
I have been using dermaveen in his bath and also the cream about 4 times a day - it has cleared up SO much and is looking a lot less 'raw' and sore. i also used dermaid on the very bad bits which cleared that up with 1 application. jhe seems a lot more comfortable now...
i will keep up the dermaveen... and if that stops working will move onto something else. my mum has super sensitive skin so i am asking her for tips (i reckon thats where he got this from).
