How to treat eczema?

Okay mamas I need help. My 3 yo has eczema on her belly and back. We took her to the dr about a month ago and he said use dove body wash/soap and then an eczema cream after her bath and to only bath her every 2-3 days. This worked wonders for about a week but now it’s just out of hand and I don’t want to take her to the dr just for eczema we go the 13th for her 3 yo check up and we plan to ask then but didn’t know if you guys had any tips to help us out until then! Thank you :blush:
