Whole milk is a key nutritional need for toddlers aged 1 to 2 years because it provides essential fatty acids and calories necessary for their rapid growth and development. During this stage, toddlers require higher fat content in their diet to support brain development and meet their energy needs. Whole milk contains a suitable balance of these nutrients that are crucial for toddlers in this age group, as they begin to transition from a primarily milk-based diet to more solid foods.
Breast milk, while beneficial, is not typically the sole source of nutrition for toddlers at this stage, as they are encouraged to gradually incorporate more diverse foods into their diets. Regular cow's milk is not recommended until after 12 months of age due to the potential for intestinal irritation and insufficient iron levels. Skim milk, on the other hand, is too low in fat and calories for toddlers, which could hinder their growth and developmental milestones.
