Formula feeding is the practice of providing infants with a specially designed milk substitute, known as infant formula, instead of breast milk. This formula is made from a combination of proteins, fats, carbohydrates, vitamins, and minerals to meet the nutritional needs of growing babies. It comes in various forms, including powder, liquid concentrate, and ready-to-use. Parents may choose formula feeding for various reasons, such as medical conditions, personal preference, or challenges with breastfeeding. Formula feeding allows for flexibility, as multiple caregivers can feed the baby, and it can be easier to measure and track the baby's intake.
