At the beginning of the evaluation, Adam appeared to enjoy playing with zoo animals with mom and the therapist. He laughed and smiled readily and paired gleeful, albeit, infrequent, babbling with gestures like pointing and guiding his mom’s hands to the toys he wanted her to play with. However, after a few misunderstandings in which neither mom nor the therapist could figure out what Adam was gesturing for them to do, Adam became highly frustrated and emotionally dysregulated. He threw himself to the floor and, in between sobs, began to bang his forehead on the floor repeatedly. His mother was worried that this self-injurious behavior had started happening more and more frequently in recent weeks.
