J.G.
I agree to consult a dr or dermatologist. I took my 20 month old to the dermatologist with smilar problems. Dr. said it was due to too much drool/moisture causing yeast to build up. She prescribed a topical cream and said I should not expect it to entirely clear up until drooling all over. I would imagine no moisture is just under her eye, so probably not the same as my son's issue. See the Dr. Also google search "peri-oral dermatitis" as that's what I thought my son's issue was at first.
