Yes, my daughter is our little allergy nightmare. She was first diagnosed with allergies at 4 1/2 months and is now almost 5 yrs. old. She had severe food allergies as a baby that caused eczema and all sorts of rashes. She was basically a vegan until age 2 when she grew out of it. However, she now has severe environmental allergies such as dust, dogs, cats, trees and grasses. We have found that the benadryl will help, but we also coat her in hydrocortizone cream during a reaction (2.5%, which is a Rx dose) and she is now on daily allergy meds to slow the reactions, but I don't know if that is an option for you which your child's age. Also, the rashes and eczema never totally go away, so we use vanicream when she is not in a breakout. It is a great lotion that you can find behind the pharmacy counter but it is not a Rx. Some pharmacies don't stock it but they will order it for you. I hope it helps.
