Flare ups at daycare

I’m a new eczema mom and so emotional about everything. My baby is almost 8 mo and has had eczema since 3.5 months.

On top of that she has fpies to banana and egg.

Her cheeks (our primary issue) seem to better at home (with some bumps and rosiness here and there) but are always SO pink and red at daycare.

None of us can figure out what the trigger is!

We bring the crib sheets. We bring the food. They only put on her what we tell them (as far as creams). She doesn’t rub her cheeks on the carpet.
They don’t go to outside.
None of the teachers wear perfume.

I’m gonna lose it.
I’ve cut dairy, gluten, and will soon be cutting eggs from my diet but trying to figure out the trigger at daycare will be the death of me (not literally).
