red dots on the baby?

I have 3 week old baby with me breastfeeding and formula feeding in these days his notice i have 3 small buttons that are very similar or red spots all over her face and her face seems oily. Is this the cause of heat or too heaty? Is this normal? how to get rid this? His stool has also changed to yellowish green with dark spots completely greeenish. Is that normal bowel movements and poo related /? thanks for the reply.

Baby acne, which is very common and of itself in a few months. And the shit is because you are breast / bottle combo:)
