Final answer:
Breastmilk and formula intake may decrease as solid foods are introduced, with foremilk and hindmilk playing different roles in feeding.
Step-by-step explanation:
Mature milk changes from the beginning to the end of a feeding. The early milk, called foremilk, is watery, translucent, and rich in lactose and protein. Its purpose is to quench the infant's thirst. Hindmilk is delivered toward the end of a feeding. It is opaque, creamy, and rich in fat, and serves to satisfy the infant's appetite.
As solid foods are introduced into the diet, the amount of breastmilk or formula an infant receives may decrease as the baby gets fuller from the solid foods. However, it is important to note that breastmilk or formula should still be a significant part of the infant's diet until they are at least 1 year old.
