Brandon is 19 and has a rare chromosomal deletion called 4q21, which causes significant physical and cognitive delays. He reacts to certain sounds, words, and phrases, and over the years we’ve learned exactly what will get the biggest laugh out of him. “Open, shut” has been one of them since he was a baby… and apparently 19 years later, it still works every single time. 😂❤️ #4q21 #DisabilityAwareness #SpecialNeedsSibling #SiblingLove #specialneeds
