Jesse had the milk rash all over his face from about 3 weeks until about 7 weeks old.. just looked like he was going through puberty and was covered in little white head pimples.

To me what yours describing sounds like pr1ckly heat.. just a form of heat rash. And it is spotty. If you search it on the net youll find it is: Tiny red spots, which usually appear on areas of the body where sweat collects, such as the armpits, back, under the breasts, chest, groin, crooks of elbows and knees, and the waist.
In babies pr1ckly heat usually starts around the neck. If it is bad, it can spread down onto the chest and back and up around the ears and face, but it seldom bothers a baby.


Jesse has, at the moment, tiny little red spots around the back of his neck and head too and it is just a heat rash as where he has it is the places he always sweats.
