What is this???? ☹️

Jennifer • All in Gods timing 🙏🏽💕

Baby has had this the last 3 days. Started on the side of of his temples, with little red bumps which I chalked up to heat rash. Now it’s on his face and the bumps are a little raised. Is this a rash, acne or eczema? Any fast remedies?

His skin was so perfect 3 days ago!
