So my daughter has been on antibiotics (amoxicillin) for an ear infection and they have caused a rash on her bottom and I’ve been using Vaseline because that’s usually what I use when she gets them and it works, but this time it’s not working. It’s red and getting worse. I’ve tried Boudreaux butt paste also. What do you guys use? I’ve been putting corn starch on it too to keep it dry. I feel so bad.😩 I usually can get it cleared up quickly with Vaseline and corn starch, but it’s not working this time.
