Yes it's possible. My son had them all the time. Get lotrimin or another athletes foot cream. It's an anti-fungal so it'll get rid of it quickly. I used an equate brand and it got rid of my daughter's in close to 2 days. Started working immediately

Yes mines had 2 from yeast. One from diapers the other I'm not sure about. Nystatin got rid of both. This is a prescription.

I took him to the doc and it was a yeast rash. Gave me some antifungal/steroid cream to clear it up. Thanks ladies !

He's shown signs of it a couple of times. I put lotrimin on it and it clears right up.

Yes, my oldest had a terrible one last year! It cleared up in less than 24 hours, but we used the prescribed cream until we ran out (just to be safe).

Thank you! I'll be taking him to the doctor tomorrow then

Yup! Very possible. My son used to always get yeast Rashes for like 4 months straight and couldn't figure out why. We got it tested and it was for sure yeast. But the dr gave us Riley cream (special formula made cream) and he had to use it twice for two weeks and has never had a problem again
