Which symptom might indicate that a baby is experiencing the letdown reflex?

The letdown reflex, also known as the milk ejection reflex, occurs when the mother's body releases milk from the milk glands in response to the baby's suckling. A key indicator that a baby is experiencing this reflex is the presence of milk around the baby’s mouth. This occurs when the baby is effectively breastfeeding and milk is flowing into their mouth, indicating that the breast is responding appropriately to the baby's feeding actions. Milk pooling or trickling from the baby’s mouth can be a clear sign that they are receiving adequate milk during a feeding session.

Other symptoms listed may not directly correlate with the letdown reflex itself. For instance, a baby pushing away from the breast may suggest they are full or uncomfortable, and sleeping during feeding could indicate drowsiness rather than an indication of milk flow. Flatulence is common in infants for various reasons but doesn’t relate to the letdown reflex specifically.
