mucousy stools

Jessrof

Our little guy has had major gas and reflux since 6 weeks he is 12w now. He began to have green poops around a month ago that has mucousy. I cut out major dairy and limited my peanuts, chocolate and caffeine and this has help tremendously with the reflux and the gas but his stools are still green
I have also been block feeding to cure an oversupply.
So my question is, if he continues to have green mucousy stools, is this ok as long as it doesn't bother him? My pedi had me bring in a stool sample to test for blood and it was negative. I have gotten conflicting advice so I would love to hear your opinions.
