… produksi ASI akan seirama dengan kebutuhan bayi. Jika bayi Anda minumnya banyak, otomatis ASI yang keluar juga banyak. Semisal yang diminum 250 ml, hormon prolaktin akan memacu kelenjar susu agar menghasilkan ASI 25 ml. Jika rangsangan bayi minum ASI semakin sering, produksi susu juga meninggi. Sebaliknya, air susu akan berkurang jika rangsangannya jarang.
In reality, the efficient supply-and-demand rhythm of normal breastfeeding—in which your baby’s increased demand for milk spurs greater milk production from you and her diminished suck ling decreases your milk supply—nearly always takes a while to establish fully and requires readjustment as your baby grows.
As your baby’s suckling time increases, milk production will also increase. Her suckling stimulates nerve endings in your breast, sending a message to your brain that results in the release of the hormone prolactin. This plays a major role in stimulating milk to be created in your breasts using substances obtained from your bloodstream. While she breastfeeds, your prolactin levels surge, ensuring continued production of milk. If breastfeeding is decreased—if your infant is fed on a restricted schedule or given supplemental formula, water, sugar water, or even a pacifier to satisfy her suckling urge—your milk production will decrease accordingly.
Human breast milk contains ingredients, as well as functions, that artificial formulas cannot replicate. Breast milk is not just different from formula, it’s different from mother to mother. The relationship between mother and baby goes further than supply and demand. Interaction between mother and child affects the composition of milk according to the child’s specific needs.
According to a new article in Nature (Dec 23/30), breast milk produced for boys contains more protein and fat than breast milk produced for girls.
“We know that boys grow faster than girls, and perhaps this is due to the milk, or the milk may be responding to the commands of the child,” said Ginna Wall, coordinator of lactation services at University of Washington Medical Center in Seattle.

It has long been understood that the breast works on a demand and supply process—baby suckles at the breast to demand milk, and the body responds by supplying it to him (via milk ejection) and then replacing what he takes and making even more if baby keeps asking. Calibration, the body’s process of figuring out how much milk to make, is designed to be an infant-driven system. Your body responds to your individual baby with a supply that is tailored to your baby’s specific needs. This is why women may have very different breastfeeding and milk production experiences from one baby to the next; each is a new and unique situation. Similarly, some women may develop a larger milk supply on one side than the other, especially if baby favors one breast over the other. Interestingly, , probably due to the fact that baby boys seem to grow a little faster and need a little more milk, thus creating a bigger milk supply in their mothers.
