|I posted before and recommended tea tree because it sounded like yeast and now that I've seen the picture I am sure. It looks just like my babies yeast rash. I would go coverless, so the yeast can dry out. Keep the bottom as dry as possible, because the yeast will grow faster in a warm wet place. As I recommended before one drop of tea tree on a wet cloth wipe every time you wash her. Tea tree will kill the yeast. Start with one, you can probably put more drops then that but just be careful not to make her skin burn. I'm remembering what my midwife told me, she said with yeast you don't want to put all sorts of creams, becauce they don't let the skin air, which can breed more yeast. She also said, try not to wipe the skin but instead dab the skin. Because lots of wiping can cause the skin to be even more sore and raw.
