Pediatrician says it’s normal I say it’s not

I EBF and I called my pediatrician in concerns with my sons poop. He’s pooping almost every diaper change causing a rash. His poop is green and sometimes with about fleck of blood in the mucus . She told me color is normal, blood is from irritation and mucus could be from a cold ( which he suddenly is sneezing stuffy and coughing ) I brought up silent reflux and milk protein intolerance , she said probably not but cut dairy to see if it helps. I’m very annoyed and trying to get other moms opinions . Poop pic to show
