Characterization of mother's milk and cow milk.

1. Big picture

This topic is not only “composition of milk.” In pediatrics, you must connect milk composition to growth, digestion, renal solute load, immunity, allergy, iron deficiency, diarrhea, and safe feeding practice.

The exam-winning idea:

Mother’s milk is biologically adapted to the human infant: lower protein and mineral load, higher lactose, better fat quality, immune protection, and easier digestion. Cow milk is designed for rapid calf growth, so it has too much protein and minerals for infants and is not suitable as the main drink before 12 months.
