Baby Biting Nipple While Nursing
The short answer
Biting during breastfeeding is a common challenge, especially when babies start teething. It can be startling and painful, but it is almost always a phase that can be managed. Babies cannot actively nurse and bite at the same time because their tongue covers the lower teeth during proper sucking. Biting typically happens at the beginning or end of a feed when the latch is not active. With some gentle strategies, most babies learn quickly that biting ends the feeding session.
By Age
What to expect by age
Some babies begin biting even before teeth erupt, using their gums to clamp down. This may happen when they are teething and their gums are sore, when the milk flow is too fast or too slow, or when they are distracted and not actively nursing. Offer a cold teething toy before nursing to relieve gum pressure. Watch for the end of active swallowing, which is often when biting occurs, and unlatch your baby when their sucking slows down.
This is the most common age for biting because teeth are actively emerging. When your baby bites, calmly remove them from the breast, say a brief "no biting" in a firm but gentle voice, and wait a moment before offering the breast again. Avoid screaming or having a big reaction, as some babies find this amusing and may bite again to get the response. Press your baby close to the breast rather than pulling away, which can cause nipple damage.
With more teeth and better jaw control, biting can become more painful. Stay consistent with your response - calmly end the feeding session when biting occurs. Most babies learn within a few days that biting means nursing stops. If your baby is going through a particularly persistent biting phase, try nursing when they are calmer and less distracted, and keep sessions slightly shorter. Some babies bite when they are finished eating but still latched.
Toddlers who bite during nursing are sometimes testing boundaries, experimenting, or communicating that they want to stop. By this age, you can use simple words to set expectations: "Be gentle with mama" or "We don't bite." If biting becomes a frequent pattern, consider whether your toddler might be ready to reduce nursing sessions. It is also normal if a biting phase makes you want to begin weaning, and that is a valid choice.
What Should You Do?
When to take action
- Your baby bites once or twice during a feed, especially when distracted or at the end of a nursing session
- Biting coincides with new teeth emerging and improves once the tooth fully comes in
- Your baby stops biting after consistent, calm responses over a few days
- Your baby bites gently with their gums before teeth have erupted
- Your baby bites so frequently that you have nipple damage that is not healing
- You have developed a painful breast infection from bite wounds
- The biting has caused a nursing strike and your baby is now refusing to breastfeed
- A bite wound on your nipple shows signs of infection such as increasing redness, warmth, swelling, or pus
- You are in so much pain from biting that your baby is not getting adequate feeds and is showing signs of dehydration

Related Feeding Concerns
I'm Worried My Baby Is Aspirating During Feeds
Aspiration means liquid or food enters the airway instead of the stomach. Occasional coughing during feeds is common and does not usually indicate aspiration. True aspiration is less common and may present as recurrent respiratory infections, a wet or gurgly voice after feeds, or chronic cough. If you are concerned, a swallow study can provide a definitive answer.
My Baby Keeps Choking on Food
First, it's important to distinguish between gagging and choking. Gagging is a normal protective reflex that helps babies learn to eat, while true choking is silent and requires immediate intervention. Most "choking" episodes parents describe are actually gagging, which is common and expected as babies explore new textures. However, if your baby frequently struggles with swallowing or shows signs of true choking, it's worth discussing with your pediatrician.
My Baby Coughs While Feeding
Occasional coughing during feeding is very common, especially in newborns who are still learning to coordinate sucking, swallowing, and breathing. It often happens with a fast milk flow or letdown. However, if your baby coughs with every feed or turns blue or has difficulty breathing, this needs medical evaluation to rule out swallowing difficulties.
Baby Falling Asleep While Nursing
It is very common for babies to fall asleep while nursing, especially in the newborn period. Breastfeeding releases hormones that make both you and your baby feel relaxed and sleepy. In most cases this is completely normal, but if your baby is not gaining weight well or consistently falls asleep within a minute or two of latching, it may be worth trying some gentle techniques to keep them feeding longer.
Baby Gagging on New Textures
Gagging on new textures is one of the most common parts of learning to eat and is a normal, protective reflex. It does not mean your baby is choking or that they cannot handle the texture. The gag reflex is positioned far forward on the tongue in young babies, which means they gag more easily. With consistent, gentle exposure, most babies gradually learn to manage new textures. Going at your baby's pace while continuing to offer varied textures is the best approach.
My Baby Holds Food in Their Mouth
Food pocketing - when a baby holds food in their cheeks or mouth without swallowing - is common and can happen for several reasons: still learning to chew and swallow, oral motor delays, sensory issues with certain textures, or simply not being hungry. Occasional pocketing is normal during the learning phase, but if it happens consistently or your baby seems unable to clear food from their mouth, it may indicate a feeding skill delay worth discussing with your pediatrician.
