Which of the following indicates a successful feeding?

A successful feeding is indicated by the baby swallowing during the latch. This action demonstrates that the baby is actively transferring milk from the breast, which is essential for effective breastfeeding. Swallowing sounds indicate that the baby's latch is well-established and that there is appropriate milk flow, which contributes to the baby's nutritional intake and satisfaction.

The presence of swallowing sounds shows that the baby is not only latched on properly but is also feeding effectively. This is an important aspect of breastfeeding as it confirms that the baby is receiving milk and that the breastfeeding process is functioning as intended. The auditory cue of swallowing reassures caregivers that the baby is engaged in a productive feeding session.

Other factors, while important in their own right, do not directly signify a successful feeding in the same clear manner as the baby's swallowing does. For instance, having a balanced intake of fluids is certainly important, but it does not reflect the immediate dynamics of the breastfeeding session itself. Similarly, the absence of flanged lips may suggest issues with latch, but it doesn't provide clear evidence of whether the baby is effectively feeding.
