This started today and wondering if it is normal??? It's on his other side to and shoulders and face

How old is he

Could possibly be a heat rash, but you should take him to his doctor.

He will be 8 weeks Friday

Yes its normal. My newborn has it too. If you take him to the doctor they will tell you its heat rash aka baby acne and to leave it alone and just bathe baby once a day with I warm water and baby soap and it will go away in a few months when baby's skin becomes less sensitive.
