Why breastfeeding matters
Breast milk is a biologically complex fluid that contains nutrients alongside a range of other components. Research suggests these include immune-related proteins, compounds that may support gut microbiome development, hormones, and growth factors. The clinical significance of each varies and continues to be studied. Breastfeeding is widely recommended as a first-choice approach by WHO, AAP, and other major health organisations where it is possible and sustainable.
How breastfeeding works
Milk production is driven by demand. Every time your baby feeds from the breast — or you express milk — your body receives a signal to produce more. The hormone prolactin drives milk production; oxytocin drives the let-down reflex. In the early days, colostrum transitions to mature milk around day 3–5. Frequent feeding in the early weeks is essential for establishing supply.
What makes breastfeeding hard
Breastfeeding is natural but not always instinctive. Common early challenges include painful latch, engorgement, cracked nipples, and uncertainty about whether the baby is getting enough. Many of these issues are solvable with the right support — a lactation consultant is often the single most effective intervention for families struggling in the early weeks.
