Baby Bit Me While Breastfeeding. Now What? A Lactation Counselor's Guide
There are few things more shocking than the first time your baby bites you while nursing.
One second you're peacefully feeding your baby. The next, you're trying not to yell because tiny teeth are somehow incredibly sharp.
If this just happened to you, take a deep breath.
As painful as it is, biting is a common phase for some babies, especially once teeth begin coming in. The good news is that it usually doesn't last forever, and in most cases, it does not mean your breastfeeding journey is coming to an end.
Let's talk about why babies bite, what to do in the moment, and how you can help prevent it from happening again.
Why Do Babies Bite While Breastfeeding?
Babies don't bite because they're being naughty or trying to hurt you.
Most of the time, there's a reason behind it.
Some common causes include:
Teething discomfort
Curiosity about their new teeth
Distraction during feeds
Boredom toward the end of a feeding
Wanting your attention or a reaction
Changes in milk flow
Falling asleep at the breast
Some babies never bite at all.
Others may go through a phase where it happens several times over a few weeks.
Neither experience is unusual.
Can a Baby Bite While They're Actively Drinking?
Not usually.
When a baby is actively breastfeeding with a deep latch, their tongue covers their lower gums and teeth. This makes it difficult to bite effectively while they're swallowing milk.
Most bites happen after the feeding has slowed down.
You may notice your baby starts playing with the nipple, turns to look around the room while still latched, smiles at you, or seems finished but hasn't quite let go yet.
Learning to recognize these cues can help you unlatch your baby before a bite happens.
What Should You Do If Your Baby Bites You?
Your first instinct might be to pull your baby away.
Try not to.
If your baby is clamped down, pulling away can actually cause more nipple damage.
Instead:
Stay as calm as you can.
Gently break the suction by placing a clean finger into the corner of your baby's mouth.
Remove them from the breast.
End the feed (even if just for a moment) before deciding whether to continue the feeding or not.
Some parents find it helpful to calmly, but firmly say something simple like:
"Ouch. Biting hurts."
Your baby may not understand every word, but over time they'll begin connecting biting with the feeding ending briefly.
There's no need to yell, flick your baby's cheek, or punish them.
They're learning.
How Can You Prevent Future Bites?
Watch for the end of the feeding.
Many babies bite when they're no longer actively drinking.
As sucking slows and your baby begins looking around or playing, gently unlatch them before they have the chance.
Offer something safe to chew before nursing.
If your baby is teething, giving them a chilled teether or breastmilk popsicle for a few minutes before feeding may help satisfy that urge to bite. See my favorite teethers here!
Reduce distractions.
Older babies become fascinated by everything around them.
Nursing in a quiet room with fewer distractions can sometimes help them stay focused on eating.
Make sure they're hungry.
A baby who just wants comfort or entertainment may be more likely to bite than actively nurse.
Stay consistent.
If biting ends the feeding for a few minutes every time, many babies quickly learn that biting means milk stops flowing.
Consistency matters much more than reacting dramatically.
My Baby Has Teeth. Should I Stop Breastfeeding?
Not at all.
This is one of the biggest fears parents have, but the vast majority of babies continue breastfeeding just fine after teeth come in.
Remember, babies can breastfeed effectively with teeth.
If your baby has a deep latch and is actively drinking, you generally shouldn't feel their teeth at all.
If you're suddenly feeling teeth throughout the entire feeding instead of just occasional biting, it may be worth working on improving your baby's latch or positioning.
What If My Nipples Are Bleeding?
Unfortunately, bites can sometimes break the skin.
If that happens:
Wash the area gently with water.
Allow your nipple to air dry when possible.
Apply expressed breast milk, nipple balm, or silverettes if you have them.
Continue breastfeeding if you're comfortable. In most cases, it's safe to nurse from a cracked or bleeding nipple.
If the wound is deep, isn't healing, or you're developing increasing redness, warmth, swelling, drainage, fever, or worsening pain, contact your healthcare provider since these can be signs of infection.
When Should You Get Help?
Occasional biting is usually just a phase.
However, it's worth reaching out to a lactation consultant if:
Biting happens at nearly every feeding.
Nursing has become too painful to continue.
Your nipples aren't healing.
Your baby suddenly develops a shallow latch.
You're considering weaning because of the biting.
Sometimes a small adjustment in positioning or latch is all it takes to solve the problem.
The Bottom Line
The first bite is memorable for all the wrong reasons.
But for most families, it's just an unfortunate phase.
Your baby isn't trying to hurt you.
They're learning how their body works while navigating teething, distraction, and a rapidly changing world.
With a little patience, consistency, and a few small adjustments, most babies stop biting just as quickly as they started.
And if you're feeling discouraged, remember this: one painful feeding doesn't define your breastfeeding journey. Like so many other challenges, this is often just another bump in the road, not the end of it
