Causes of Frequent Biting in Babies While Breastfeeding and How to Address It

Breastfeeding is an intimate, loving moment between mother and baby. However, for some mothers, this experience can become uncomfortable when the baby suddenly bites the nipple. Many mothers feel surprised, hurt, or even traumatized, sometimes leading to the desire to wean earlier than planned. This phenomenon is quite common, especially in babies entering the active oral phase. This article will explore in depth the reasons why babies frequently bite during breastfeeding, why it happens, when it should be a concern, and how to address it gently and effectively. With the right understanding, mothers can restore the comfort of breastfeeding without fear.

Is It Normal for Babies to Bite?

Many mothers wonder whether biting during breastfeeding is a sign of a problem. In fact, biting is a natural part of a baby’s developmental phase, especially when gums become itchy due to teething or when the baby is learning to explore their surroundings. 

However, even though it is considered normal, this behavior still needs to be addressed to prevent it from becoming a repeated habit. Mothers need not feel guilty or rush to wean. By understanding the reasons why babies frequently bite during breastfeeding and taking the right steps, this habit can be minimized.

Common Causes of Babies Biting During Breastfeeding

Several factors can prompt a baby to bite the mother’s nipple. These range from teething, losing focus, imperfect latch, to emotional responses. Here’s a detailed explanation:

1. Teething

When teeth begin to emerge, a baby’s gums feel itchy and uncomfortable. Biting the mother’s breast becomes a natural way for the baby to relieve this discomfort. This is the most common reason babies bite during breastfeeding, typically occurring between 4–9 months of age.

2. Tired or Distracted Baby

Often, babies bite at the end of a feeding session when they are full or bored. At this stage, the baby is no longer focused on sucking and may start playing with the breast instead. This factor is a less obvious but frequent cause of biting during breastfeeding.

3. Imperfect Latch

Incorrect breastfeeding positions can make it easier for a baby to bite due to inadequate suction. Additionally, using bottles with differently shaped nipples can cause nipple confusion, leading the baby to bite more often. This cause can usually be prevented by adjusting the feeding position.

4. Reflex or Emotional Response

Babies who are stressed, angry, frustrated, or disturbed by changes in their environment, sounds, or lights may bite spontaneously. Emotional factors are often overlooked by parents as a reason for biting during breastfeeding.

Gentle Ways to Handle a Baby Biting During Breastfeeding

Biting in babies usually begins between 4–9 months, during the active oral phase when they like to put various objects in their mouths. At this stage, the gums are preparing for  teething, making itching the most common reason for babies to bite during breastfeeding.

This behavior can also reappear when babies start eating solid foods (MPASI), as breastfeeding becomes a secondary activity and they are easily distracted. Handling a biting baby requires calmness and patience. The following steps can help:

• Stay Calm but Firm: Avoid shouting to prevent startling the baby. Simply say “no” in a gentle voice so the baby learns that biting is not acceptable behavior.

• Release the Breast: Use your pinky finger to gently break the latch when the baby bites to prevent further pain.

• Improve Latch: Ensure the baby’s feeding position is correct for optimal suction, reducing the risk of biting.

• Offer a Cold Teether: Give a chilled teether before feeding if the baby is teething to soothe the gums.

• Watch for Fullness Cues: End the feeding session before the baby becomes bored, minimizing biting caused by distraction or loss of focus.

Why Hegen Is the Ideal Solution When Babies Start Biting

If the nipples are very sore from biting, mothers can consider expressing breast milk and feeding it via a bottle temporarily. However, it is important to ensure that the bottle used is safe and does not cause nipple confusion. 

This method should only be used when necessary, not as a permanent weaning solution. In this way, mothers can address the reasons babies frequently bite during breastfeeding without compromising continued breastfeeding.

Hegen offers an innovative solution for mothers facing the biting phase. Its nipple design closely resembles the mother’s nipple, facilitating a smooth transition without disrupting the breastfeeding routine. 

The anti-colic system and gentle flow prevent the baby from feeding too quickly, which can trigger biting. Made from soft, BPA-free materials, Hegen bottles are safe for babies with sensitive gums. Additionally, the bottles can be used to store, pump, and feed breast milk without transferring it to another container. 

All these features help mothers address the causes of frequent biting during breastfeeding in a practical and hygienic way.

When to Consult a Doctor or Lactation Counselor

Although most cases of babies biting during breastfeeding can be managed at home, there are times when professional help is necessary. Early consultation can help identify the right solution and minimize the risk of recurring biting. Watch for the following signs:

1. Causing Serious Nipple Injury

Deep or persistent wounds can lead to prolonged pain and increase the risk of infection. Medical attention can speed up healing and help maintain a steady milk supply.

2. Changes in the Baby’s Feeding Behavior

For example, sudden refusal to breastfeed, excessive fussiness, or appearing unusually tired during feeding. These behaviors may indicate an underlying health issue that requires a doctor’s evaluation.

3. Mother Experiences Trauma or Considers Stopping Breastfeeding

A lactation counselor can provide emotional support, teach proper breastfeeding techniques,  and offer strategies to help mothers regain confidence in nursing.

By recognizing these signs and seeking early consultation, mothers can address problems more quickly, ensuring breastfeeding remains a comfortable and positive experience even during the phase when babies frequently bite.
