Does not feeling engorged for two or three hours mean low milk supply?
Generally speaking, whether a lack of breast fullness after two to three hours indicates low milk supply should be comprehensively evaluated based on the mother's specific condition and the baby's feeding needs. If concerned, it is recommended to consult a healthcare professional or lactation consultant. Detailed analysis is as follows:

If the mother is several days or weeks postpartum, with established and stable milk production, and the baby has longer intervals between feedings, not feeling full in the breasts after two to three hours is usually not a sign of low milk supply. At this stage, the breasts have adapted to the baby’s needs and produce milk on demand rather than continuously accumulating large volumes that cause engorgement. As long as the baby shows strong swallowing sounds during nursing, appears satisfied afterward, and gains weight appropriately, it indicates sufficient milk supply.
However, if the mother is in the early postpartum period when milk production is not yet stabilized, or if the baby feeds frequently, a lack of breast fullness after two to three hours—especially accompanied by weak swallowing sounds during feeding, persistent crying after nursing, or slow weight gain—may indicate insufficient milk supply. In such cases, milk production may not yet meet the baby’s demands, so attention should be paid to lactation status and breastfeeding techniques should be adjusted promptly.
Do not rely solely on the sensation of breast fullness to assess milk volume. Instead, evaluate based on the baby’s feeding behavior and growth patterns. Regularly allowing the baby to nurse frequently can help stimulate milk production. Ensure adequate rest and proper nutrition, and avoid anxiety, which can negatively affect lactation. If low milk supply is suspected, seek guidance from a qualified lactation specialist for personalized support, and avoid supplementing with formula unnecessarily.
