I think Isabelle has eczema - Im going to ask my CHN next week but wanted to get some advice here too.

Its on both of her cheeks kind of near her ears - red, rough, dry and raised skin so Im assuming its eczema. She also has little dry, rough patches on her legs here and there.

Ive never had it in my life and neither has DH so we are a bit clueless.
What types of things cause it??
ShouId I try an elimination diet of certain things like dairy??
Should I take her to a paediatric dermatolgist?
Any product recommendations??? - Ive used moogoo on it I was using it for her cradle cap which has since cleared up but even that doesnt fully clear it up.

TIA
