Hello my 4 month old has developed a rash? Before it was just red marks on her belly and back. I saw the doctor and they prescribed me “zero cream” for the dryness. It’s helped with the dryness however it’s now bumpy and kind of in a a cluster. She has a rash when she was a newborn but it went after 2 weeks. I’m not sure if this is eczema anyone have any ideas?
