Yeast Infection

I gave my daughter a bath last night and realized her private area (mainly her clit) was bright red like blood and so was the rest of the inside of her vagina. I took her to the doctor today and it’s an doctor I’ve seen twice and don’t like. He was in and out within 5 mins, he just gave off that vibe that you don’t like and don’t feel comfortable with, he said it’s just an diaper rash and it’ll go away. But it’s not even on her butt, it’s literally inside of her private area. He acted as if he didn’t care. I called my husbands aunt that use to be nurse and she said the way that I’m describing it is an start to a yeast infection. She just got off a bunch of antibiotics bc of an ear infection and flu.
