From the Kansas Health Institute:
JJ Krentz turned away from his iPad and looked up as a blond woman walked into his classroom at Parsons State Hospital and Training Center.
With help from his teacher, he stood from his chair and greeted his mother, Tiffanie Krentz.
He knew she was coming and so he parroted the two-word phrase he’d been hearing all day from others when he asked them about “mama.”
“Gotta wait,” JJ said, grinning.
