I think baby has yeast infection :/

I noticed since my daughter had a bath two days ago, she’s had a little rash on her bottom along with thick discharge with a few diaper changes during the day. I’ll admit, with her bath I added the Johnsons baby vapor soap since she’s been a little congested. I think it’s what caused it. Besides that my daughter is acting normal and seems to feel fine.

The rash is going way since I have been putting aquaphor on it. Before I call the dr, did anyone have this problem with their baby girl? Will probiotics help with the discharge? Natural remedies? Coconut oil? I’d like to try like I do with myself before I make her take antibiotics...please no judgement, just experiences and advice thank you 💗
