We found the only effective steroid creams were Eumovate and Elocon. Have you tried either of them?
I was told that there had to be 15 mins between the Diprobase/Epaderm whatever you're using and the steroid cream.
We usually bath her then put the Diprobase on then her pjs and put the steroid cream on just before bed.
Have you tried wet wrapping? we did it for a while when the excema was v bad and it really helped. We used comfi fast vests/tights and propaderm cream. She hated having it done but it was well worth it as she slept through every night she was wrapped.
As for weaning- we didn't see the dietitan until she was about 7/8 months so had already begun weaning. Go slowly and introduce foods one at a time to try to identify what makes flare ups worse.
Our dietitan said food allergy is the most common cause of bad excema in infants under 1.
Dd2 had RASTs at 8mo as I insisted on her being tested. They normally prefer to wait until age 1. Think results are clearer after 1. The RAST is a blood test they take quite a few tubes and we had a playworker distracting her at same time. She didn't cry. Results take a while though- aboout 6 wks.
Skin pricks she could have at age 1 and the arm is stretched out and the forearm scratched with a needle and the potential allergens are dropped onto each scratch. She only cried a little bit at the end.
Then you wait 15 mins- getting them not to scratch their arm(hard!) and go back to have results immediately which are measured in milimetres.
Dd2 will be re tested at 18mo to see if she's outgrown any.
My e mail is ellenbowers1 at hotmail dot co dot uk if either of you want to mail me I'll return your e mail with some photos of how bad she got and what she's like now.
Hope I've answered everything!
