Breastfeeding is influenced by both milk production and milk transfer. While milk supply depends on hormonal signaling and milk removal, milk transfer depends on a baby’s feeding mechanics, including suction, tongue movement, and coordination. When babies remove milk efficiently, the body receives signals to continue producing milk. When feeding mechanics are less effective, milk supply may gradually change. Understanding both sides of breastfeeding allows parents to approach feeding challenges with greater clarity and compassion while exploring supportive solutions.
