Why should babies stop formula at 1 year?

Babies should transition away from formula at around one year because their nutritional needs change as they begin to eat a more varied diet. At this age, they can generally consume whole cow's milk and a range of solid foods, which provide the necessary nutrients for growth and development. Continuing formula beyond this age may limit their exposure to diverse flavors and textures essential for their dietary advancement. Additionally, excessive formula intake can contribute to obesity and nutritional imbalances.
