It is easily digested and efficiently used. Mature milk contains all the nutrients your baby needs in the first six months of life, including fat, carbohydrates, proteins, vitamins, minerals and water. The content of this transitional milk includes high levels of fat, lactose, water-soluble vitamins and more calories than colostrum. On the third day, your baby is normally drinking about 300–400ml every 24 hours, and by the fifth day, up to 800ml. ![]() Milk starts to be produced in larger amounts between two and four days after delivery, making your breasts feel full. ▶ How does your breast milk change, as your baby grows older? In addition, epidermal growth factor found in this special milk helps to prepare the lining of your baby’s gut to receive the nutrients of mature milk. Colostrum also provides important immune protection to your baby when he or she is first exposed to the microorganisms in the environment. Vitamin E is an important anti-oxidant and Vitamin K plays a role in helping blood to clot. Vitamin A is important for protection of the eyes and often makes the colostrum yellowish in colour. Colostrum is rich in white cells and antibodies, especially IgA, and it contains a larger percentage of protein, minerals and fat-soluble vitamins (A, E and K) than later milk. ▶ What are the different stages of milk production?īreast milk has three different and distinct stages: colostrum (in the first two to three days after delivery), transitional milk (from day seven to 14) and mature milk (after two weeks).Ĭolostrum is a special milk that is produced in small amounts (about 40–50ml on the first day) but is all your baby normally needs at this time. After delivery, levels of progesterone and oestrogen fall rapidly, prolactin is no longer blocked, and your milk secretion begins. ![]() ![]() However, milk is not yet secreted, because progesterone and oestrogen, the hormones of pregnancy, block this action of prolactin. In preparation for the production of milk, prolactin levels increase markedly during pregnancy. The growth and development of your mammary (breast) tissue is controlled by the hormone prolactin. ▶ How does your body adapt to produce milk when you’re pregnant? Breast milk is not just food for baby – it provides potent health-giving properties for mom, too.ĭr Jonathan Buckley, a paediatric nephrologist at Mediclinic Constantiaberg, offers a closer look at this natural wonderfood.
