How long after delivery does breast engorgement typically occur?

Breast engorgement typically occurs 2 to 5 days after delivery as the mother's milk supply increases. This increase in milk production is a natural response following the hormonal changes associated with childbirth. During the first few days postpartum, the breasts may fill with colostrum, which gradually transitions to mature milk. As the milk comes in, the breasts can become full, swollen, and possibly painful, leading to engorgement.

The timing of 2 to 5 days post-delivery aligns with when many mothers begin to experience those physiological changes as their bodies adjust to breastfeeding. Hormones associated with lactation, particularly prolactin, rise as the baby begins to nurse, leading to increased milk production. It's essential for new mothers to be aware of this process so they can seek help if engorgement becomes uncomfortable or if they experience difficulties with breastfeeding.
