Every feed hurts. Not a little tender - genuinely painful, toe-curling pain, and your nipples look worse each day rather than better. You've tried every latch position a lactation consultant showed you and something still feels stuck.
This is one of the more common reasons feeding stays painful past the first fortnight, and it has a name, a straightforward assessment, and a fix that's simpler than most parents expect.
What tongue tie actually is
Tongue tie (ankyloglossia) happens when the thin strip of tissue under the tongue, the lingual frenulum, is shorter or tighter than usual, restricting how far the tongue can move. Because a deep, effective latch depends on the tongue extending well past the lower gum, a restricted tongue can make it hard for a baby to draw milk efficiently, however good their positioning is.
It's present from birth and varies widely in severity - some cases barely affect feeding at all, while others make a comfortable latch nearly impossible no matter what you try.
Signs worth getting checked
- Persistent nipple pain or damage that doesn't improve with repositioning
- A clicking sound during feeds, or milk leaking from the corners of the baby's mouth
- A baby who tires quickly at the breast, feeds very frequently, or seems to fall asleep before finishing
- Slow weight gain despite frequent, seemingly effective feeds
- A tongue that looks heart-shaped when crying, or can't extend past the lower gum
How it gets assessed
A lactation consultant, GP, or paediatrician can usually assess tongue mobility with a simple physical check alongside watching a full feed - the feed itself often tells them more than the anatomy alone, since some ties restrict feeding significantly and others barely at all.
This is why two babies with a similar-looking tie can have very different feeding experiences, and why the decision to treat is based on function, not appearance.
What the release procedure actually involves
If a release is recommended, the procedure itself (a frenotomy) is typically very quick - often just seconds - using sterile scissors or a laser on the thin tissue, usually with no anaesthetic needed given how few nerve endings are in that area for young babies.
Most babies can feed immediately afterward, and many parents report an improvement in latch comfort within the first few feeds, though it can take a little time and some stretching exercises for the tongue to build new movement patterns.
If something feels off
Painful feeding is common in the early days, but pain that isn't easing by two to three weeks, despite good positioning, is worth a proper assessment rather than something to push through indefinitely.
Tongue tie is well understood, straightforward to check for, and - when it is the cause - one of the more fixable reasons feeding has been hard. It's worth ruling in or out early rather than assuming pain is just part of the deal.
