What is one potential consequence of introducing cow's milk before the age of 12 months?

Introducing cow's milk before the age of 12 months can lead to iron deficiency anemia. This is because cow's milk is low in iron and can interfere with the absorption of iron from other sources. Additionally, infants who consume cow's milk may not receive adequate nutrition overall, as cow's milk can be replacing iron-rich breast milk or iron-fortified formula.

Moreover, cow's milk can cause gastrointestinal irritation and source of occult blood loss in the intestines, leading to further iron deficiency. Infants require adequate iron in their diet, particularly as they grow and develop. Iron deficiency anemia can have significant effects on an infant's growth, cognitive development, and overall health, making it crucial to adhere to recommended guidelines regarding the introduction of cow's milk into an infant's diet.
