At the age when most babies are beginning to use their first words, my little brother remained non-verbal. My parents went to a doctor regarding this. The doctor said, “Wait, see what happens.” My parents waited. Time passed and the doctor confirmed that he was experiencing a significant speech delay.
More time passed. At a certain point…around the age my brother was a toddler…my parents believed that he was beginning to use words, but that he was struggling to enunciate them correctly. And a specialist confirmed this. He was speaking, finally, but he had a severe impediment.
