Advice needed for allergies and eczema

Hello, I recently found out through skin prick tests that my 11 month daughter is allergic to a bunch of things including sesame, egg, kiwi, mustard, pineapple, cashew and pine nuts 😢 it’s a relief to find this out in a way to try to relieve her bad eczema but also I’m so anxious how to handle all these allergies. Do I just wait and hope they will go away? Is there anything at all I could try or do to help the chance for any of the allergies to lessen or go away instead of just hoping while avoiding all the foods. The dr also told us to use steroids (Eumovate) every day on her skin for 8 weeks which seems too harsh. I’d appreciate any advice. Thanks very much!
