The investigators have developed BUILT in hopes of empowering families to adopt and sustain healthy food, sleep, and exercise routines that optimize child focus, attention, and behavior. Over 6-weeks, the BUILT program will explore what science says about the effects of sleep, nutrition, and exercise on brain development and behavior; investigate the food, sleep, and exercise routines of the world's best athletes and intellectuals; and experiment with home routines to find those that best fits with participating families. It is hypothesized that families participating in BUILT (N=150) will show significant improvements in child health behaviors (sleep, nutrition, physical activity, recreational screen time), child mental health (ADHD symptoms \[primary outcome\], child functional impairment), child physical literacy, and family dynamics (cohesion, structure, communication) from baseline to posttest.
