The doctor is most likely correct. However if you worry the doctor may be wrong I would seek a second opinion or go to a dermatologist (skin doctor).
If you go with this doctor diagnosis, follow his treatment plan to the letter. If it does not work, get another appointment.
I would think the doctor knows best but wouldn't hurt to get second opinion but you think the doctor would of took blood work, she could have allergies too .
Try Polysporin Triple. It's an antibiotic so will not harm the Child. I use it on the occasional Cold Sore, which is a form of Herpes, and it works very well.
