Possible yeast diaper rash & thrush in toddler.

Kelsey • TTC baby #2❤️ Baby girl born 03/26/2019🎀💗

Is there anything over the counter I can give her or do I need to call the doctor? She’s 15 months and i saw some whiteness in her mouth that seems to be going away and now she has a rash on her privates that looks different than regular diaper rash
