Final answer:
Cow's milk should not be introduced to a child until 12 months of age due to several reasons, including the lack of essential nutrients, the risk of allergic reactions, excessive fat content, and interference with iron absorption.
Step-by-step explanation:
Cow's milk should not be introduced to a child until 12 months of age due to several reasons:
- Lacks essential nutrients for infant development: Cow's milk does not contain the optimal balance of nutrients needed for a baby's growth and development.
- May cause allergic reactions: Cow's milk is one of the most common food allergens, and introducing it too early can increase the risk of allergies or intolerances.
- Contains too much fat for infants: Cow's milk has a higher fat content than breast milk or infant formula, which can be difficult for infants to digest.
- Interferes with iron absorption: Cow's milk contains high levels of calcium and casein, which can interfere with the absorption of iron from other foods, leading to iron deficiency anemia.
