Breastfeeding and Lactation Complete Reference Cheat Sheet

Breastfeeding is a hormonally driven, supply-and-demand system in which milk production is established and maintained by frequent, effective milk removal — making the first two weeks after birth the most critical window for long-term success. It sits at the intersection of maternal physiology, infant oral anatomy, and behavioral cues, meaning that small adjustments to positioning or latch can resolve the majority of problems. The single most important mental model is this: your body cannot know how much milk to make unless milk is consistently removed, so every feed — whether at breast or by pump — is a direct signal to increase or sustain supply.
