Foremilk refers to the initial milk that comes out during lactation. There are several synonyms for this term, including colostrum, early milk, pre-milk, and transitional milk. Colostrum, also known as first milk, is produced during the first few days after giving birth and is rich in nutrients and antibodies. Early milk and pre-milk are terms used to describe the milk produced during the early stages of lactation, which is thinner and less nutrient-dense than later milk. Transitional milk refers to the milk produced during the transition from colostrum or pre-milk to mature milk. Understanding these synonyms for foremilk can help new mothers better comprehend the various stages of lactation.
