【What are the different from each stage?】
- Colostrum is the secretion produced during the first few days (1-7 days) after birth and differs from both transitional and mature milk. It contains a higher amount of protein, less fat and a number of immunising factors for the newborn.
- It is the transition from colostrum to mature milk, where lactation is established and production of milk begins in the breast tissue. Transitional milk is produced from approximately day 8 – 20.
- Mature milk is produced from 20 days after birth, onwards. It can vary in and between individuals and the energy can vary between 270 and 315 kJ per 100mL. This is largely due to the variation in the fat content, as the fat of the milk received by the infant increases as the feed progresses. Mature milk continues to provide immune factors and other important non-nutritional components to the infant.
【What are the nutrients in breastmilk ?】
Breastmilk contains all the nutrients the infant needs for proper growth and development.
- Fats – Essential fatty acids and long-chain polyunsaturated fatty acids
- Carbohydrates – The principal carbohydrate of human milk is lactose.
- Minerals, vitamins, and trace elements.
