Rash Question

Bailey • Girl Mom 💝 “Cool Mom” 😎 VI.XIX.MMXIX Due in October #2!!

Hi ladies, I have an important question about a spreading rash on my daughter’s back. She was taking amoxicillin from last Tuesday until Saturday and had diarrhea and developed a very bad diaper rash. Based on online pictures of severity I would say moderate-severe. It was almost cleared up or so I thought until last night and today where it seems to be worse than ever. The first picture I will be inserting is a picture of her back from last night and the second picture will be from this afternoon. As you can tell the rash is spreading. Thank you for any input!

Here’s a picture of my sweet girl just to show her and her cuteness off:
