Colic might be a symptom of vestibular dysfunction. Never thought about it that way, as suggested by chiropractor Dr Jan Hoeve from the Netherlands in his landmark paper in the high-impact journal, Frontiers in Pediatrics this past May: (https://www.frontiersin.org/articles/10.3389/fped.2021.668457/full). Have always thought that colic is due in part to dietary sensitivities, but have also said that colic/reflux is not ONLY a digestive issue...it is a brain issue. Now we have a groundbreaking theory that might explain what is really going on with colicky babies.
