My daughter is having rashes like this all over her body. It itches sometimes but not always so I'm ruling out that it's eczema. She's currently having a bit of cough and runny nose. Anyone knows what it is?

Minor allergy to something. May be clothes or food. Best to see ur pediatrician. If u are breast feeding please continue to do so. Avoid any new food or clothing material. Handwash clothes for a few days with baby detergent.
