Tongue tie—medically known as ankyloglossia—has become a hot topic in parenting circles, and for good reason. When present, it can significantly impact breastfeeding and cause real pain for nursing mothers. However, tongue tie has also become somewhat over-diagnosed, leading to unnecessary procedures. As a pediatrician who performs frenotomies when clinically indicated, I want to help you understand what tongue tie actually is, how to recognize the signs that matter, and when intervention truly helps. Not every baby with a visible frenulum needs treatment—but some absolutely do.
