Help with baby eczema 😢

Dia
My daughter is now 11 months and she has severe eczema. She had eczema since she was 3 months old.It got worse as months went by.We saw an allergist she suggested using cortisone allergy medication and giving her bleach bath.Even though its so scary and it made me so nervous giving my daughter bleach bath it helped couple of times but now it doesnt help her anymore.I used to give her allergy medication so she feels better and sleeps well.Its non drowsy which was good.She doesnt have a refill for that medication so im waiting for her appointment in the end of June.She is allergic to nuts,dairy red meat and egg.I exclusively breastfeed her and i stopped eating everything she is allergic to but she still itches like crazy every day.I sometimes give her bleach bath twice a day so she gets some relief because she is so uncomfortable she cries.It doesn't help.I try my best to soothe her to fall asleep but she wakes up and itches and cries so much.😣I would appreciate any suggestions or any recommendations.😊
