Key points

  • Benefits of breastfeeding include better tolerance of feeding, reduced gastrointestinal disease and improved intelligence.
  • Breast milk provides the right balance of energy, protein, carbohydrates, fat, electrolytes, minerals and vitamins that your newborn needs.
  • Breast milk contains antibodies that infants need to fight infections during the first few months of life.
  • The health benefits of breastfeeding and breast milk are well known and are especially important while your baby is in hospital.
  • If you cannot breastfeed or provide breast milk for your baby, commercially manufactured formula milks are available.

The terms 'mother' and 'breastfeeding' are used throughout our documents; we recognize and respect that individuals and families may use other preferred terminology.

It is universally accepted that human breast milk is the best source of nutrition for newborn babies and infants. Breastfeeding also has many non-nutritive benefits that lead to the best health and development of the baby. Breast milk acts as a medicine for babies who are sick or premature. Any amount of breast milk is beneficial for your baby's health—every drop counts!

According to the World Health Organization, "exclusive breastfeeding for the first six months is the optimal way of feeding infants. Thereafter, infants should receive complementary foods with continued breastfeeding up to two years of age or beyond."

Numerous studies have shown the benefits of providing human milk to newborn babies and young infants, which include better tolerance of feeding, reduced gastrointestinal disease and improved intelligence. 

There are also very important health benefits for the mother as well. Early establishment of breastfeeding after delivery makes the uterus contract back to its original size faster. Breastfeeding also reduces the risk of breast and ovarian cancers.

Normal, healthy newborn babies have enough energy stores in their bodies to keep them going for the first few days of life. The small amounts of "milk" they receive from their mothers in these early days, called colostrum, offers high levels of protective immunological benefits and sugars for energy and prepares the baby for the larger volume of milk that mothers produce by the third or fourth day after delivery.

Newborn babies and young infants need specific amounts of energy, protein, carbohydrates, fat, electrolytes, minerals and vitamins. These are all provided in the right balance by your breast milk, with the added benefit of important antibodies to help your baby fight infections during the first few months of life. Human breast milk is designed for human babies, and all substitute feeding preparations contain fewer ingredients than have been identified in human milk. Of the over 200 identified elements of human milk that interact in this complex fluid, about 30 can be artificially produced in infant formula.

Should you have difficulties feeding your baby at the breast, despite assistance by a breastfeeding specialist, you can purchase or rent hospital-approved breast pumps to express your breast milk to feed it to your baby.

If you cannot breastfeed or provide breast milk for your baby, commercially manufactured formula milks are available for feeding babies.
