What could this be?

Caitlin

OK, so I am not sure if this is an allergy rash, heat rash, or something else. It doesn't bother her and she doesn't want to scratch it or anything. I gave her a bath with aveeno baby and noticed after that (I'm allergic to a lot of facial products myself) which is why I thought allergy but it hasnt gotten better. When I looked up heat rash it looks similar but I don't feel like she's getting that hot. We do live in the south though so its pretty hot outside regardless. Any thoughts on what it is? Asking her pediatrician at her 2 month appointment next week.
