Multiple allergies....help

Hi hope your all ok?

My little girl is 8 months old and in January was diagnosed with a milk allergy, at the beginning of April she was diagnosed with wheat intolerance and at the end of April mushroom. She has been given anti histamine by the doc to help with the swelling should she have Any more reactions, we still have to try her on soya and egg I am just a little scared as I don't want her to have a reaction as they make her so unwell.

She is under the care of a dietician and We have an appointment with an allergy doctor but not until the middle of July!

Any help or advice would be nice, thanks in advance. X
