Tongue-tie, painful feeding and nipple damage

What it is, and what it causes

Tongue-tie is a short, tight or thick strip of tissue under the tongue that restricts how far the tongue can move. It is present from birth and affects a small percentage of babies.

It matters only if it causes a problem. Many babies have some restriction and feed perfectly well, and those need nothing done.

Signs in the baby: difficulty latching or staying latched, sliding off, clicking sounds while feeding, feeds that take very long, falling asleep at the breast quickly and waking hungry, poor weight gain, and reflux-like symptoms from swallowing air.

Signs in the mother: pain throughout the feed rather than just the first seconds, a nipple that comes out flattened or wedge-shaped, cracks, bleeding, blocked ducts and repeated mastitis.

Look for the tongue itself: unable to lift to the roof of the mouth, unable to extend past the lower gum, or with a heart-shaped or notched tip when the baby cries.

Bottle-fed babies can also be affected, with dribbling, clicking and slow feeds.

Assessment and treatment

Assessment should be by someone who watches a full feed, not just looks in the mouth. Function matters more than appearance, and a tie that looks dramatic but feeds well needs nothing.

See a paediatrician, a lactation consultant, or an ENT or paediatric surgeon. In India, lactation consultants are available in most cities and are frequently the ones who identify it.

Division — frenotomy — is a quick procedure in which the tissue is released. In a young baby it is usually done without general anaesthesia, takes moments, and the baby can feed straight afterwards.

Bleeding is minimal and complications are uncommon. A posterior tie may need a different approach and sometimes an ENT surgeon.

Improvement is not always immediate. Some feeds improve within a day; others need weeks of feeding support afterwards, because the baby has to unlearn a compensating pattern.

Be cautious both ways: division is sometimes recommended for babies where it is not the problem, and it is sometimes refused where it clearly is. A second opinion is reasonable, and a feeding assessment before any procedure is the right sequence.

The other causes of painful feeding

Latch, which is by far the commonest cause. A shallow latch pinches the nipple and is fixable with hands-on help in a single session.

Positioning: the baby not close enough, the head not free to tilt back, or the mother hunched over the baby rather than bringing the baby to her.

Thrush, which typically causes burning pain continuing after the feed, often with a shiny or flaky nipple and white patches in the baby's mouth. Both mother and baby need treating.

Vasospasm, where the nipple blanches white after a feed with a sharp burning pain, often worse in the cold.

Engorgement and blocked ducts, especially in the early weeks.

Mastitis: a hot, red, painful area with fever and flu-like aching. This needs same-day medical attention.

And nipple damage from an early poor latch that persists after the latch is fixed, which needs the damage treated as well as the cause.

Painful feeding is common and it is not normal, and it is the leading reason Indian mothers stop breastfeeding earlier than they wanted to. It is worth getting proper help rather than being told to persevere.

When to see a doctor

Call 108 or go to the nearest hospital immediately if your baby: is breathing fast, grunting, or drawing in beneath the ribs; has blue or grey lips, tongue or face; is floppy, unresponsive or very difficult to wake; has a fit; has a temperature of 38C or above at under three months; is not feeding at all; or has a rash that does not fade when pressed with a glass.

Same-day medical care for: a red, hot, painful area on the breast with fever or flu-like aching, which is mastitis; or a baby who is not feeding at all.

See a doctor or lactation consultant within days for: pain that lasts through the feed, cracked or bleeding nipples, a baby who cannot latch or keeps sliding off, poor weight gain, or fewer wet nappies than expected.

Ask specifically for a feeding assessment rather than a look in the mouth, and for referral if division is being considered.

Frequently asked questions

Q: Does tongue-tie always need cutting? — No. It is treated when it is causing a feeding problem, not because it is visible.

Q: Does the procedure hurt? — It is quick and babies usually settle at the breast within moments. Most cry more at being held still than at the release.

Q: Will it affect speech later? — Most tongue-ties do not affect speech. This is a common reason given for division and it is not well supported for the majority of cases.

Q: Is painful feeding just normal at the start? — Some tenderness in the first days is common. Pain through the feed, cracks or bleeding are not, and they mean something is fixable.
