Baby rash

Erika

My 6 month old (3months adjusted)

Has a rash on her belly. It’s tiny raised bumps. Some skin color and some pink.

It doesn’t seem to bother her.

She doesn’t have any other symptoms.

Any idea what this can be?

I’d rather not take her to the doctors office if it’s not serious. She’s a preemie so I don’t want to expose her to more dangerous germs.

Help?!
