So the other day Athena woke up with a rash from hell. When it happens which isn’t often I put antibiotic ointment on it and a little bit of powder so she doesn’t chaff usually that clears it up super quick. I haven’t been able to get it cleared though at all. She doesn’t seem bothered by it when I change her, I changed her diaper brand, got water wipes and got max strength desitin but I honestly don’t know what else I can do. She isn’t running a fever & other than the rash she’s acting completely normal so I didn’t call the doctor yet but I’m thinking maybe I should????. Any other suggestions?? I just feel like the worst mom that I can’t get this cleared up for her☹️ but she hardly gets them so I’m at a loss on what to do now
