One possible contributor
Restricted tongue movement may contribute to latch or milk-transfer difficulties in some infants. However, breastfeeding discomfort and feeding problems often have other explanations, including positioning or milk-supply concerns.
A pediatric clinician and skilled lactation professional can consider the whole feeding situation. Looking at the frenulum alone is not enough to decide what will help.
Support before a procedure
The American Academy of Pediatrics recommends considering nonsurgical approaches first. Support can include improving positioning and latch, checking milk transfer and monitoring growth.
If significant functional difficulty persists despite appropriate support, discuss whether a release is indicated, its risks and what improvement is realistic. Evidence suggests short-term reduction in nipple pain for some parents, but feeding outcomes are variable. Upper lip frenulums are normal; evidence does not support releasing them solely to improve breastfeeding.
