Aim 2. Determine the intervention's efficacy for improving young children's glycemic control and parent's management of eating and physical activity behaviors. The investigators hypothesize that the Phase 2 pilot will demonstrate that relative to usual care, the intervention will evidence 1) Significantly better glycemic control (i.e., HbA1c <8.5% and higher percentage of BG levels in the 100-200 mg/dl range, per ADA recommendations) and 2) Significantly fewer child feeding and activity behavior problems (e.g., food refusal, dawdling at mealtimes, physical inactivity). 3. Mediating effects of eating and physical activity on glycemic control will also be explored.
