Hi,
I know how you feel.
DD has severe eczema since she was little as well. They said usually its not an intolerance to food but the environment. Dust and dust mite is one of the worse culprits.
Some tips the hospital gave us for
DD was:
1. Remove all dusty things from
DD's room. If she has a fav furry toy i had to freeze it over night to kill the dustmite
2. Get mattress cover (called Allergend) or change her covers every few days (I decided to go with that as havent a chance to get the allergend covers so not sure how good that is)
3. Bathe her every 2-3 days and quickly and use a bath oil (i use QV bath oil)
4. When drying her, pat her instead of rub her with the towel
5. Moisturise moistrise moisturise - I use MooGoo MSM on her bum and QV cream (not the lotion) on her body
Her eczema has subsided but she still has outbreaks though (i think due to changes in weather)
Goodluck
