Why do Babies go Through a Biting Phase?


Becoming a parent is an incredible journey filled with tender moments and unforgettable milestones, but it also comes with its fair share of challenges. Among these challenges is a phrase that often leaves parents both puzzled and occasionally frustrated – the biting phase in babies. If you’ve ever found yourself on the receiving end of a tiny but surprisingly sharp set of baby teeth, you’re not alone. This developmental stage can raise countless questions in the minds of caregivers: Why do babies go through a biting phase? Is it just teething, or is there more to it? How can parents and caregivers best navigate this seemingly perplexing behavior?

In this comprehensive article, we’ll not only answer these questions but also take a deep dive into the biting phase, exploring its multifaceted causes, helping you recognize its subtle signs, and providing a treasure trove of strategies for effectively managing this essential yet challenging part of early childhood development.

What is the Biting Phase?

The biting phase in babies, often referred to as the tendency for infants and toddlers to bite objects, people, or even themselves, is a common occurrence during early childhood development. Typically commencing around 6 to 9 months of age and potentially continuing until approximately 3 years old, this phase manifests in various scenarios. Babies may engage in biting as a response to teething discomfort, as a means of exploring their surroundings through sensory input, as a non-verbal form of communication to express emotions or needs, and even as a component of their burgeoning social development.

Reasons behind the Biting Phase

There could be numerous reasons behind babies changing their habits and shifting to a biting phase, including:


Teething is a major factor in the biting phase. During this time, a baby’s gums become sore and tender as their first set of teeth begins to emerge. Biting can provide relief from the discomfort by applying pressure to the gums.

Exploratory Behavior


Infants are natural explorers, and their mouths act as vital tools for this exploration. Biting is one way they investigate their surroundings, helping them understand the world through tactile and oral sensations.


Babies lack the verbal skills to express their needs and emotions fully. Biting can become a non-verbal form of communication, signifying emotions such as frustration, excitement, or even affection. It’s a way for them to convey what they’re feeling when they can’t articulate it verbally.

Sensory Stimulation

The biting phase can also be driven by a desire for sensory stimulation. Babies may find the tactile sensation of biting, the texture of objects, or the taste interesting and pleasurable, encouraging them to continue this behavior.

Pain Relief

Beyond teething, babies might use biting as a method to alleviate discomfort in other parts of their bodies. This could include biting their own fingers or hands when they experience general discomfort or pain.

Social Development

As babies grow, they start to interact with their environment and other people. Biting can sometimes be a part of this social development as they learn about cause and effect and how their actions impact others.

Signs and Symptoms

Recognizing when a baby is going through a biting phase is crucial for effective management. Look for signs such as increased drooling, swollen gums, and the baby’s tendency to put objects in their mouth. It’s important to differentiate between biting driven by developmental factors and aggressive behavior.

How Long Does the Biting Phase Last in Babies?

The duration of the biting phase varies from child to child. It typically starts around 6 to 9 months and can last until about 3 years old. Factors like individual temperament and teething discomfort can influence how long it persists. Most children naturally outgrow this phase as they acquire language skills and better ways to communicate their needs.

Coping Strategies for Parents and Caregivers

Understanding and managing the biting phase can be challenging, but there are effective strategies to help parents and caregivers navigate this period:

  • Positive Reinforcement: Encourage good behavior and provide rewards and praise when the child refrains from biting.
  • Diversion Tactics: Redirect the baby’s attention by offering appropriate teething toys or engaging them in other activities.
  • Communication and Education: Teach babies alternative ways to express themselves and educate caregivers about the biting phase to ensure consistent responses.

When to Seek Professional Help

While the biting phase is a common developmental stage, there are instances where it may become a concern. If a child’s biting behavior is severe, persistent, or causing harm to themselves or others, consult a paediatrician or child psychologist for guidance on managing the behavior effectively.


The biting phase in babies is a challenging but temporary aspect of early childhood development. Understanding the reasons behind it and employing effective coping strategies can make this phase more manageable for parents and caregivers. Remember that patience, empathy, and consistent responses are key to helping your child navigate this developmental stage successfully.
