Hello everyone. I feed my child often because milk comes and leaks, so I have to wear diapers. Because of this, I think I'm getting breast rashes. It was the same during pregnancy, my belly itched terribly, now the belly is gone, but my breasts itch. It really bothers me, I constantly scratch, I go everywhere scratching. I wash my breasts, I try to do more air baths, but because of the diapers, it seems like the skin isn't breathing. What can I do?
