The Moment That Makes You Jump
Nursing is going along peacefully, and then it happens. A bite. You jump, you yelp, and your baby looks startled or even amused. If biting has crept into your breastfeeding relationship, you're probably wondering why it's happening and whether you can make it stop without ending nursing altogether.
Biting while nursing has a few common causes, and teething is the one most parents reach for first. But latch mechanics, including a tongue restriction, can also play a role. Understanding why your baby bites is the first step to gently fixing it.
At Latched Beginnings in Austin, we help nursing parents troubleshoot biting. Here's what's going on and what to do.
Why Babies Bite While Nursing
Biting usually isn't about your baby trying to hurt you, even when it sure feels that way. There's almost always a reason behind it, and identifying the reason points you toward the fix. The common causes range from teething discomfort to latch issues to simple distraction.
One reassuring fact: a baby who is actively, deeply nursing usually cannot bite, because the tongue covers the lower gum during a proper latch. Biting tends to happen at the start or end of a feed, or when the latch is shallow, which is itself a useful clue.
The Common Causes of Nursing Bites
Here are the usual culprits and what each one looks like.
Teething Discomfort
Sore, swollen gums make babies want to chew and apply counter-pressure. A teething baby may bite to relieve the ache, often around the start or end of a feed.
A Shallow Latch
When a baby isn't latched deeply, the teeth or gums are closer to the action. A shallow latch makes biting mechanically easier, which is one reason latch quality matters.
Distraction or End of Feed
Older babies who are full, bored, or distracted may clamp down as they pull off or lose interest. This is common as babies become more aware of their surroundings.
Tongue Restriction Affecting the Latch
A tongue-tie can keep a baby from latching deeply or keeping the tongue properly positioned over the lower gum, which can make biting more likely. If biting comes with other latch and feeding issues, the tongue is worth considering.
Low Flow or Slow Letdown
Some babies bite in frustration when the milk flow slows, as a way of trying to get more.
The Tongue-Tie Angle
Here's a connection that often gets overlooked. During a proper deep latch, the tongue extends forward and covers the lower gum, which physically protects you from the teeth. A baby with a tongue-tie may not be able to maintain that tongue position, leaving the lower teeth or gums more exposed during the feed.
So while teething is the most common cause of biting, a baby who bites frequently and also has a history of shallow latch, clicking, or feeding struggles may be dealing with an underlying restriction. The biting is a symptom of the same latch problem, not a separate issue. This is worth keeping in mind if biting is persistent rather than occasional.
Gentle Ways to Respond to Biting
Your reaction shapes whether biting becomes a habit. A few gentle, effective strategies. Stay as calm as you can, since a big dramatic reaction can either scare or delight a baby into doing it again. Watch for the end-of-feed signs and unlatch your baby before they clamp down. Keep your baby engaged and minimize distraction during feeds. Offer something cold and safe to chew before nursing if teething is the issue.
If your baby does bite, calmly break the latch by slipping a finger into the corner of their mouth, set a gentle boundary, and continue. Most babies stop within a few feeds when you respond consistently and calmly. If biting is frequent and paired with latch problems, addressing the underlying latch or tongue-tie may resolve it more lastingly.
When Biting Points to Something More
Occasional biting during teething is normal and usually short-lived. But if your baby bites frequently, can't seem to maintain a deep latch, and has a history of feeding difficulties, the biting may be one more sign of a latch issue worth evaluating.
In that case, the goal isn't just to stop the biting; it's to understand why the latch isn't protecting you in the first place. A deeper, more stable latch, whether through positioning support or addressing a restriction, often resolves the biting along with the other issues.

Frequently Asked Questions
Why does my baby bite while nursing?
Common causes include teething discomfort, a shallow latch, distraction or the end of a feed, a slow milk flow, and sometimes a tongue restriction affecting the latch. A deeply nursing baby usually can't bite because the tongue covers the lower gum, so biting often happens at the start or end of a feed or when the latch is shallow.
Can a tongue-tie cause my baby to bite while breastfeeding?
It can contribute. During a proper deep latch, the tongue extends over the lower gum and protects you from the teeth. A tongue-tie may keep a baby from maintaining that tongue position, leaving the lower teeth more exposed. If biting comes with a shallow latch, clicking, or feeding struggles, the tongue is worth considering.
Does teething always cause biting while nursing?
Teething is the most common cause, since sore gums make babies want to chew and apply counter-pressure, but it's not the only one. A shallow latch, distraction, slow flow, and underlying latch issues can also cause biting. If biting is frequent and paired with feeding difficulties, the cause may be more than teething alone.
How do I get my baby to stop biting while breastfeeding?
Stay calm rather than reacting dramatically, watch for end-of-feed cues and unlatch before your baby clamps down, keep your baby engaged, and offer something cold and safe to chew before nursing if teething. If your baby bites, calmly break the latch and set a gentle boundary. Most babies stop within a few feeds with consistent, calm responses.
Can I keep breastfeeding through teething and biting?
Yes, most parents do. Biting during teething is usually occasional and short-lived, and responding calmly and consistently resolves it for most babies within a few feeds. If biting is frequent and tied to latch problems, addressing the underlying latch or a tongue-tie often resolves it more lastingly so you can keep nursing comfortably.
Why can't my baby keep a deep latch without biting?
If your baby frequently bites and can't seem to maintain a deep latch, an underlying issue like a tongue-tie may be preventing the tongue from staying properly positioned over the lower gum. The biting can be a symptom of the same latch problem rather than a separate issue, which is why an evaluation can help.
Is occasional biting while nursing normal?
Yes. Occasional biting, especially during teething or at the end of a feed, is normal and usually short-lived. It becomes worth evaluating when it's frequent, your baby can't maintain a deep latch, and there's a history of feeding difficulties, which together can point to an underlying latch issue worth addressing.
