excema is awful,I really feel for you.
My ds had quite bad excema and the only thing that
helped,and we did try most things(probiotics/fish
oil/all sorts of creams, but steroids and antihistamine helped control it when it got really bad.
I was lucky and was referred to the local hospital dermatology clinic which we could go to if we were having a flare up.That was a real godsend,both physically and emotionally.They reassured me that the steroids wouldn't harm ds or thin his skin. They didn't get rid of it completely but improved it a lot.
As for clothes ,we wet wrapped ds and just put loose clothes on the top.
Go and see your dr if it's getting too much!It is emotionally draining for the whole family and the more support you get the better.
as for sleeping I found a really light weight sleeping bag from tchibo that stopped him getting to his legs.His face was always bleeding in the morning during a flare up.
On a more positive note ds is now 3y5m and his excema has virtually gone!He's got asthma now instead
