My 4 month old baby has red colored rashes on his both the cheeks. It is rough to touch. Rashes are there on his cheeks since birth. Sometimes, they disappear but suddenly reappear causing roughness and redness on his both the cheeks. Initially 1.25 months, I used gram flour and milk for his bath but post that we bathe him with water only. We don't apply anything on his face. At times, it also feels that he has little itching on these rashes. Please suggest how this can be cured.
