Common Tongue Tie Signs in Babies:

If you are reading this in the middle of the night, perhaps following a painful or frustrating feed, please know you aren’t alone. As a midwife supporting families across London I often meet parents who feel they are 'failing' at breastfeeding, only to discover that a physical restriction, a "tongue tie" is the hidden problem.

Breastfeeding shouldn't be painful. While every feeding journey has its learning curve, persistent pain, clicking sounds, or a baby who never seems satisfied are often clinical signals that something more is going on. In this guide, I’ll walk you through the five most common signs I look for during a specialist clinical assessment in your own home, helping you understand if a frenulotomy (tongue-tie division) could be the key to protecting your breastfeeding bond.

Tongue Tie Symptoms for Baby Include:

  1. Poor weight gain - A baby with a restricted tongue has to work twice as hard for half the milk. You might notice your baby falls asleep at the breast out of exhaustion, or may he or she barely latches? This cycle can lead to slow weight gain and parental exhaustion.

  2. Painful gas or reflux - When a baby can’t create a perfect "vacuum seal" due to a tongue tie, they swallow a lot of air while feeding (aerophagia). This air trapped in the digestive tract leads to a distended, painful tummy, excessive gassing, and the inconsolable crying often labeled as "colic."

  3. Long/constant feeding - Does it feel like your baby is never truly full? A baby with a restricted tongue often tires out before they can get a full belly. They might fall asleep at the breast or bottle out of pure exhaustion, only to wake up 20 minutes later hungry again. This is a classic sign of an inefficient latch.

  4. Leaking milk out of the mouth - While some dribbling is normal, milk consistently leaking from the corners of the mouth during a feed suggests the baby cannot create a functional seal. This is common in both breastfed and bottle-fed babies with a tongue-tie

  5. Clicking sounds while feeding - Do you hear a clicking sound while your baby sucks? This happens when the baby loses the "seal" or vacuum on the breast or bottle because the tongue cannot maintain its position. This often leads to the baby swallowing excess air, causing wind and colic.

Identifying these signs is the first step, but a physical clinical assessment is the only way to confirm a diagnosis.
