Aim 1. Pilot test and refine innovative and feasible assessment and intervention components for T1D control in young children, and examine acceptability and impact in parents of young children. At the conclusion of Phase 1, this Aim results in an innovative intervention program, supported by state of the art assessment tools and preliminary data. The investigators hypothesize that the intervention will be associated with high feasibility and acceptability, improved T1D management, and reduction of behavioral challenges related to eating and physical activity.
