Breastfeeding difficulties as a result of tight lingual and labial frena: a case report

A breastfed baby with impending failure to thrive resisted assuming a wide-mouthed, flanged-lip position at breast. A lingual frenotomy was only partly successful in correcting his breastfeeding problems. Following a labial frenectomy, the baby was better able to flange his upper lip against the breast. He then began breastfeeding with full efficiency.
