Anyone know what this could be?

I have a 5 day old son and anywhere that he rests his head on me, I’m breaking out in a rash. It’s nowhere else and it’s not itchy. He doesn’t have it. I’m just really concerned.

It also is just making me feel very ugly and I don’t know what to do. I’m going to start having to put a receiving blanket between him and my skin which is the last thing I want to do.
