The clicking noise while nursing is a significant symptom that can indicate a lip or tongue tie in breastfeeding infants. This clicking sound often occurs when the infant is unable to maintain a proper seal around the breast. A frenulum that restricts the movement of the tongue or the upper lip can lead to ineffective latching, causing the baby to lose suction intermittently. As the infant pulls away slightly to re-establish a latch, the clicking sound can become apparent.

This issue is especially relevant in the context of breastfeeding, as an inadequately latching baby might be unable to transfer milk effectively, leading to further feeding challenges for both the infant and the mother. Although other symptoms can be associated with breastfeeding difficulties, the clicking noise is a distinct indicator tied specifically to the mechanics of latching and can alert caregivers to the possibility of a tongue or lip tie that requires further evaluation.
