Final answer:
Infants are best on a demand feeding schedule as it allows them to eat when they are hungry and stop when they are full. Breast milk composition changes to meet the infant's needs.
Step-by-step explanation:
Infants are best on a demand feeding schedule as it allows them to eat when they are hungry and stop when they are full. Demand feeding takes into account the individuality of each infant, as their appetite and feeding patterns can vary.
Breast milk composition changes during the first days of lactation and in the course of a single feeding.
During the first few days after birth, the mother produces colostrum, which is rich in immunoglobulins that boost the newborn's immune system. As lactation progresses, the composition of breast milk changes to meet the infant's needs. The early milk, known as foremilk, quenches the infant's thirst, while the later milk, known as hindmilk, satisfies the infant's appetite.
