Does anyone have any experience with ringtail? I think one of my 3 month old boys has it. His tail is bumpy and constricted in places. He also has a bit of dry skin on his back. From what I've read, it's mostly a hydration issue. I've been coating him in olive oil, but how often should I do this? Unfortunately, a humidifier is not an option right now. Is there anything I could feed him to increase his moisture intake?
