As your child continues to grow, most of their caloric intake will come from food. After 1 year of age, breastmilk or formula may not be a part of their daily nutrition. However, it is still important to ensure children receive plenty of healthy fats as part of their daily nutrition. Healthy fats are important for brain growth and development. It is recommended that toddlers eat healthy fats that come from foods such as avocados, peanut butter, full-fat Greek yoghurt or even olive oil. These healthy foods support brain development and provide plenty of nutrients.
