Breastfeeding a Teething Baby: What to Expect and How to Cope
Teething can bring new challenges to breastfeeding — including distracted feeding, sudden biting, and shorter sessions. If your once-calm nursing routine feels unpredictable, you’re not alone.
Here’s what’s happening — and how to handle it.
When Do Babies Start Teething?
Teething often begins around 4–7 months, though timing varies. Some babies show symptoms before teeth appear, while others surprise parents with a sudden tooth.
Common signs:
Increased drooling
Chewing on hands or toys
Fussiness
Slight sleep disruption
Gum swelling
Teething does not usually cause high fever or severe illness — if symptoms seem extreme, check with your pediatric provider.
Why Is My Baby Biting During Breastfeeding?
Biting can happen for a few reasons:
Curiosity about new sensations
Gum discomfort
Distraction
Slower milk flow
End of feeding (when baby is no longer actively drinking)
The good news? Babies cannot bite while actively sucking. The tongue covers the lower gum during effective nursing.
Most biting happens:
At the beginning while positioning
At the end of a feed
When baby is distracted
How to Prevent Biting
Try these strategies:
✔ Watch for early hunger cues — don’t wait until baby is frantic
✔ Keep feeds focused (dim room, less stimulation)
✔ Offer a chilled teething toy before feeding
✔ If biting happens, calmly unlatch and say, “No biting. That hurts.”
✔ End the session briefly if needed
Consistency helps babies learn quickly.
Should I Stop Breastfeeding When Teeth Come In?
Not at all. Many parents continue breastfeeding comfortably well beyond the first teeth. A proper latch remains key — if baby slips into a shallow latch, gently relatch to protect your nipples.
If soreness develops:
Check latch depth
Use expressed milk on nipples to promote healing
Consider a lactation consultation to assess positioning
My Baby Is Nursing More During Teething — Is That Normal?
Yes. Some babies seek comfort at the breast more often during teething discomfort. Others may nurse less due to gum sensitivity. Both patterns can be normal temporarily.
Follow your baby’s cues while keeping milk removal consistent to protect supply.
