Formula feeding is the practice of providing infants with a specially designed milk substitute known as infant formula. This formula is made from a combination of water, carbohydrates, proteins, and fats, and is fortified with vitamins and minerals to support a baby's growth and development. It is an alternative to breastfeeding and can be used exclusively or in combination with breast milk. Parents may choose formula feeding for various reasons, including medical conditions, personal preferences, or challenges with breastfeeding. Formula feeding allows caregivers to measure and control the amount of nutrition their baby receives, and it can also enable other family members to participate in feeding.
