Does anyone know what this is? **UPDATE**

I’m a FTM and my baby is four days old. I noticed these little bumps on her, they seem to disappear and then show up on other parts of her body.

We don’t have any bugs in the house so I’m super confused/concerned. She has an appointment tomorrow though, just looking for some ideas. They don’t seem to bother her. Saw her pediatrician today, it is white blood cells coming to the surface according to him, and is completely harmless.
