The goal of this randomized control trial is to determine the impact of post-frenotomy manual manipulation on revision rates and breastfeeding outcomes. We hypothesize that post-frenotomy manipulation will reduce the rate of sublingual frenulum regrowth, and subsequently frenotomy revision rates, thereby improving breastfeeding performance. Infants with ankyloglossia undergoing frenotomy will be randomized into two groups: the intervention group (post-frenotomy manipulation) and the control group (no intervention). Parents in the intervention group will be instructed to perform tongue stretching and suck re-training exercises four times daily for 2-3 weeks, beginning 24 hours post-procedure. To monitor adherence and assess any complications, investigators will conduct a follow-up phone call one week after the procedure. Parents in the control group will not be instructed to perform any post-procedural manipulation. All participants will have a mandatory in-person follow-up 2-3 weeks postoperatively, during which breastfeeding outcomes and the need for frenotomy revision will be evaluated.
