Leо is аn 8-yeаr-оld bоy who lives with his pаrents and attends the third grade, where he is typically a strong student. Over the last two months, he has missed eight school days and strongly resists leaving home in the morning. At drop-off, he often clings to his mother's jacket, cries uncontrollably, and frequently experiences severe stomachaches and headaches that prompt calls home from the school nurse. Leo's teachers report that he struggles to concentrate in class, constantly worries that his parents will be late to pick him up, and refuses to participate in extracurricular activities or playdates that require him to be away from his caregivers. At home, he requires a parent to sit with him until he falls asleep and often wakes up multiple times a week from nightmares about being lost or harmed.
