Why Is My Child Biting? Causes and How to Help

If your child has started biting, you might be wondering: Why is my child biting? Is this normal? And how can I help them stop?

Biting can feel confronting for parents, particularly when your child bites another child at home, during play or at child care. But for babies and toddlers, biting can be part of development as they explore their world and learn to communicate, manage strong emotions and interact with others.

Rather than simply seeing biting as ‘bad behaviour’, it can help to look beneath the behaviour and consider what your child may be trying to communicate.

Babies and toddlers may bite because of teething, exploration, frustration, strong emotions or because they don't yet have the words or self-control to express what they need.

There isn't one reason children bite, and the reason can be different for every child.

Common reasons can include:

Teething: Babies and toddlers may bite down to relieve discomfort in their gums.
Exploration: Young children use their mouths as one of the ways they investigate and learn about their world.
Limited language: A toddler might bite when they don't yet have the words to say ‘stop’, ‘mine’, ‘help’ or ‘I need space’.
Frustration: Sharing, waiting for a turn or having another child interrupt their play can feel overwhelming.
Big emotions: Excitement, anger, distress and frustration can sometimes result in biting.
Tiredness or hunger: Children can find it harder to manage their responses when they're tired, hungry or not feeling well.
Overstimulation: Busy, noisy or highly stimulating environments can sometimes contribute to biting.
Cause and effect: Particularly for babies, biting can be part of discovering what happens when they do something.

Australian early childhood guidance from Starting Blocks also identifies factors including teething, frustration, tiredness, difficulty communicating, sharing and turn-taking as possible reasons for biting.

The reason may also change over time, which is why understanding the individual child and what is happening around the biting is so important.

Repeated biting can happen because toddlers are still developing language, impulse control, emotional regulation and social skills.

Toddlers can experience very big feelings without yet having all the tools they need to communicate or manage them.

Instead of focusing only on the biting itself, look for patterns.

Does it happen when your child is tired? During busy group play? When another child takes a toy? While they're waiting for a turn? When they're excited or overwhelmed? At a particular time of day?

Understanding what happened before the bite can often tell us more than the biting itself.

Respond calmly, set a clear boundary and then try to understand what led to the biting.

Simple language can help. You might say, ‘Biting hurts’ or ‘I won't let you bite’, while calmly helping your child move away from the situation.

Once everyone is safe and settled, think about what was happening immediately beforehand.

If your child was frustrated because another child had a toy, you might help them practise saying ‘my turn?’ or asking an adult for help. If they're teething, offer something appropriate to chew. If they're overwhelmed by a busy environment, helping them move into a quieter experience may be useful.

The aim isn't to shame or embarrass your child. It's to help them gradually develop another way to communicate what they need.

Consistency matters too. When the adults around a child respond in similar, calm and predictable ways, it can make it easier for them to understand the boundary and develop alternative ways to respond.

If your child is biting at childcare, educators can work with you to identify possible triggers and develop consistent strategies to support your child.

Hearing that your child has bitten someone can be upsetting. It doesn't mean your child is ‘naughty’, nor should biting define how we see them.

At Sanctuary Early Learning Adventure, our educators look beyond the incident itself.

Depending on the individual child, we may consider:

What happened immediately before the bite?
Was the child tired, hungry, teething or overwhelmed?
Was another child entering their play or using something they wanted?
Were they waiting for a turn?
Did they have the language they needed to communicate what they wanted?
Is there a pattern involving a particular environment, experience or time of day?
What could we change or introduce to better support them?

This is where knowing a child well matters. Educators can use their observations and their relationship with the child to look for patterns, adjust the environment, provide closer support during known trigger points and help children develop other ways to communicate.

A consistent approach between home and child care can help children learn new ways to express their feelings and needs.

At Sanctuary, partnership with families is an important part of responding to biting. What you notice at home may help educators understand what they're seeing at the centre, and vice versa.

Perhaps your child has been teething or sleeping poorly. Maybe there has been a change at home. You might have noticed new words emerging or a particular situation that causes frustration.

Similarly, educators may notice that biting tends to happen during a particular part of the day, when the environment becomes busy or during certain social situations.

Bringing those observations together gives us a much fuller picture of what your child might be communicating and how we can support them.

When a child is bitten at child care, the immediate priority is caring for the child who has been hurt while also supporting the child who has bitten.

It's completely understandable for parents to feel upset when they learn their child has been bitten.

Early learning services have responsibilities around responding to incidents, caring for the child who has been hurt and communicating with families.

It's also important that the child who has bitten continues to be treated with care and respect.

Rather than labelling a child as ‘a biter’, educators can focus on understanding what happened, reducing the likelihood of it happening again and helping both children feel safe and supported.

Starting Blocks advises that services should also maintain the confidentiality of the child who has bitten when communicating with other families.

The most useful starting point is identifying why your toddler is biting and helping them develop another way to communicate or respond.

There may not be a quick fix, but there are practical ways you can support your child.

Look for triggers.
Notice when, where and with whom biting tends to occur. Patterns can help you understand what is driving the behaviour.

Give them useful words.
Simple phrases such as ‘stop’, ‘help’, ‘my turn’ and ‘I need space’ can give toddlers another way to communicate.

Name their emotions.
You might say, ‘You're frustrated because you wanted the truck.’ Giving children language for emotions can help them gradually learn to express those feelings themselves.

Respond calmly and consistently.
Clear, predictable responses help children understand the boundary without creating shame around the behaviour.

Support regulation.
Rest, predictable routines, physical activity and opportunities for quieter play can help when children are becoming overwhelmed.

Offer an appropriate alternative.
If teething or oral exploration appears to be contributing, offer an appropriate teether or safe item designed for chewing.

Notice what is going well.
Give your child attention when they're communicating, playing cooperatively or interacting gently, rather than allowing biting to become the behaviour that receives the biggest response.

There isn't one age at which every child stops biting, although biting often becomes less common as children's communication, emotional regulation and social skills develop.

Every child's development is different.

Rather than focusing solely on age, consider how often the biting occurs, what appears to trigger it, whether the frequency or intensity is changing and how your child responds to support.

If biting is frequent, causing injury, continuing despite consistent support, or you're concerned about your child's behaviour or development more broadly, consider speaking with your GP, child and family health nurse or another appropriate health professional.

Biting can be difficult for everyone involved: the child who is hurt, the child who has bitten, parents and educators.

But children are still learning.

When adults respond calmly, look beneath the behaviour and work together, these moments can become opportunities to help children develop communication, emotional regulation, empathy and social skills.

At Sanctuary Early Learning Adventure, we see children as capable and competent learners. When challenging moments arise, our role is not simply to stop a behaviour. It's to understand what a child may be communicating and give them the relationships, language and support they need to develop new ways of responding.

Because sometimes the behaviour we see is only one small part of what a child is trying to tell us.
