This study, called the Milk-Tot Study, is looking at how different types of milk affect a child's weight. Researchers want to understand if giving children whole milk (3.5% fat) or 1% milk after age two impacts their risk of obesity. You or your child would be randomly assigned to receive either whole milk or 1% milk for one year, provided free of charge. You would also receive quarterly phone counseling from a Registered Dietitian about introducing and continuing the assigned milk. The main goal is to see how your child's waist-to-height ratio changes over 12 months. This study is for children aged 23 to 48 months, and parents must be willing to provide only the assigned milk type, have access to a smartphone and internet, and be able to read English or Spanish.
