We will enroll n=464 12 month olds who are drinking >2 (non-water) bottles or sippy cups/day, from 2 Bronx WIC sites. Bottle/sippy cup use, anthropometrics, and dietary intake will be assessed at Baseline, and again at 15, 18, 21, and 24 months of age. FYCS nutritionists (blinded to group assignment) will collect two 24 h recalls of all beverage and solid intake, and enter it into the Windows-based Nutrition Data Systems for Research software, the premiere dietary data collection and nutrient density calculation tool. WIC nutritionists will administer the Intervention at Baseline, and (blinded to outcomes) as needed at follow-ups.
