What is the term for the first milk produced by the breasts after delivery?

The first milk produced by the breasts after delivery is known as colostrum. This yellowish fluid is highly nutritious and is rich in antibodies, which provide essential immunological protection to the newborn during its initial days of life. Colostrum is produced in small quantities, which is sufficient for the newborn's needs, as their stomachs are small and they require concentrated nutrition.

Colostrum sets the foundation for the infant's digestive system and helps establish the gut flora, aiding in digestion and building the immune system. This early milk is often described as being more viscous and contains higher levels of protein, vitamins, and minerals compared to mature milk, making it particularly beneficial for newborns.

The other terms refer to different components or stages of breast milk. Foremilk refers to the milk that is produced at the beginning of a feeding session, which is typically more watery and helps quench the infant's thirst. Hindmilk is produced later in the feeding and is richer in fat, providing more calories to the baby. The term "milk of a mother" is not a recognized term in the context of breastfeeding and does not accurately describe the specific type of milk produced after delivery. Thus, colostrum is the definitive term for the first milk produced
