Why is it important not to limit fats in an infant's or toddler's diet?

Fats are crucial for infants and toddlers as they support brain development, which is particularly rapid during the early years. Healthy fats provide essential fatty acids that the body cannot produce on its own, and they also play a vital role in the absorption of fat-soluble vitamins (A, D, E, and K). Limiting fats can hinder growth and overall nutritional balance, potentially affecting cognitive and physical development. Therefore, including healthy sources of fat in their diet is essential for optimal health and development.
