What is the minimum age to switch from formula milk to full-fat cow's milk?

• A. 6 Months
• B. 12 Months
• C. 9 Months
• D. 18 Months

Answer: (B)

Introducing full-fat cow’s milk around the first birthday is recommended because during the first year a baby’s iron needs are best met by breast milk or iron-fortified formula. Cow’s milk is relatively low in iron and, if used as the main drink too early, can contribute to iron deficiency and place extra strain on the kidneys due to its higher protein and mineral content. By about 12 months, most children are eating a varied diet with iron-rich foods, and their bodies are better able to handle cow’s milk as a primary drink. Using full-fat milk supports growth and brain development, and it should be part of a balanced diet rather than replacing iron-rich foods. After age 2, you can consider lower-fat options if advised by a clinician, but the minimum age to switch is about 12 months.
