What is the rule of thumb regarding portion sizes for toddlers and preschoolers?

A common rule of thumb for portion sizes for toddlers and preschoolers is to serve about one tablespoon of each food per year of age. For example, a 3-year-old may receive 3 tablespoons of vegetables, grains, and protein. Additionally, it's important to focus on a balance of food groups and allow children to listen to their hunger cues. Encouraging a variety of foods helps ensure they receive the necessary nutrients for their growth and development.
