Girls, hi. Can you tell me, please, about a two-month-old baby, he's constantly spitting up on the photo, it disappears and appears during breastfeeding. I don't eat much anymore. I can't figure out what allergy or maybe this is acne in newborns? Mostly pimples only on cheeks. Also, rough and sometimes colorless.
