The phone call no parent wants to receive from daycare:
"Your toddler bit another child."
Embarrassing. Alarming. And surprisingly, it is very
common.
Toddler biting is one of the most distressing
behaviours for parents and carers to deal with. But it is also one of the most
misunderstood. Toddlers who bite are not aggressive. They are not mean. They
are small people whose brains and bodies are not yet equipped to handle the
demands being placed on them.
This guide explains why toddlers bite, what the
research says about responding effectively, and the strategies that stop it.

toddler guide.
Is Toddler Biting Normal?
Yes. Biting is most common between 12 and 36 months,
which is the age group most likely to bite of any age.
Growing Room Child Development Centers confirms toddlers
aged 12 to 36 months are the age group most likely to bite. They are still
developing language skills, emotional regulation, and impulse control. All
three are directly linked to biting behaviour.
A study cited in Parents Together found that almost all
children bite, kick, or hit at some point until they develop better language
skills and learn that words get better results. It is not a sign of a deeply
aggressive child. It is a sign of a developing one.
Important
fact from ZERO TO THREE - Biting is common in toddlerhood and almost always
has an obvious cause. When the cause is identified and addressed, biting typically
stops. The behaviour itself is never acceptable, but the child should not be
labelled as "a bitter." Labels damage self-esteem without fixing the
behaviour.
Why do toddlers bite?
Understanding the cause is the most important step.
Different causes need different responses.
They cannot express themselves yet
This is the most common cause. A toddler who does not
have words for "I am overwhelmed," "I want that toy," or
"I do not want you near me" resorts to physical expression.
ZERO TO THREE confirms: hitting and biting are often
signs of communication difficulties. As language grows, biting almost always
decreases.
Sensory Seeking
Some toddlers bite because of sensory needs. The mouth
provides powerful sensory input, pressure, texture, and proprioception. A toddler
who bites may be seeking deep pressure through their jaw.
Connect Pediatric Occupational Therapy explains that children with sensory sensitivities may bite when they feel overstimulated,
anxious, or out of control. It is a self-regulation strategy, a clumsy,
harmful one, but a genuine attempt to manage their sensory experience.
Signs that biting has a sensory component include
biting in crowded or noisy environments, biting with changes in routine, and
chewing non-food items throughout the day.
Frustration and Anger
A toddler who cannot get what they want, is prevented
from doing something, or has a toy taken, often responds physically. If they do
not yet have words for the feeling, the body acts first.
Excitement
Some toddlers bite not out of frustration but out of
excitement. When they are very happy, very aroused, or very interested in
another person, biting can be a form of affectionate overstimulation.
This confuses parents who see the bite come after what
looked like lucky play. It is still a behaviour that needs redirecting, but
the response differs from frustration biting.
Exploration and Cause and Effect
Babies and young toddlers explore the world through
their mouths. Biting a person and observing the reaction is, from a
developmental standpoint, the same kind of experimentation as banging a spoon
on a pot.
Teething
Teething discomfort leads some toddlers to bite for the
pressure it puts on sore gums. This is more common in younger toddlers between
12 and 18 months when back molars come through.
What NOT to Do When Your Toddler Bites
Do Not Bite Back
Biting a child to "show them how it feels" is
never appropriate. It teaches that biting is acceptable when someone bigger
does it. It also frightens and confuses the child without teaching them what to
do instead.
Do not Over-React
A large, dramatic reaction, shouting, lengthy
lectures, and visible anger can accidentally reinforce the biting. If a toddler
is seeking attention or testing cause and effect, an explosive response
delivers exactly what they were seeking.
Do Not Label Them
Never call your child "a biter." Child
development specialists are consistent on this point. Labels harden into
identity and damage self-esteem without teaching any alternative skills.
Do Not Use Shame
Shame does not teach. It damages the parent-child
relationship without reducing the behaviour.
How to Stop Toddler Biting - What Actually Works
Respond Quickly and Calmly
When biting happens, it moves physically between the
child who bit and the child who was bitten. Address the bitten child first,
briefly and warmly. Then calmly turn to the child who bit.
State firmly and simply: "No biting. Biting
hurts." One time. No lecture.
NCBI StatPearls advises stating "no biting"
in a neutral tone, then redirect. A quiet redirection is more effective
than an emotional response.
Identify the Pattern
Watch for the circumstances in which your toddler
bites. Is it always in crowded situations? When a particular toy is involved?
When they are tired or hungry?
Pathways.org advises: identify the triggers, and you can
intervene before the bite happens. Step in during the build-up, not after the
damage is done.
Common patterns to watch for:
- Biting more - tiredness
- Biting in noisy, crowded environments - overstimulation
- Biting when a specific child comes close - personal space trigger
- Biting after a nap is a sleep-related behaviour
Provide Appropriate Sensory Input
For sensory-seeking biters, provide alternative outlets
for the same input.
ZERO TO THREE recommends: give a firm "bear
hug" when you sense a toddler is feeling stressed and about to bite. This
provides the deep pressure they need without harm to others.
Other sensory alternatives include: chewy food items
during snack time, chewable jewellery designed for toddlers, textured chew
toys, crunchy snacks, and firm physical play like rolling on the floor or
jumping.
Teach Alternative Actions
A toddler who bites needs replacement behaviours, not
just prohibitions.
Teach them: stomp their feet, squeeze your hand, say
"mine" or "stop," or bring a toy to you. Practice these in
calm moments, not during the incident itself.
The National Association for the Education of Young
Children suggests teaching children simple social language: "no,"
"Stop," and "my turn." These words give toddlers a functional
alternative to physical expression.
Address Language Development
If your toddler bites frequently and is also behind in
language development, the two are likely connected. A speech-language pathology
assessment is worth requesting early.
Building language through reading, narration, and
responding to every communication attempt is the single best long-term
intervention for toddlers who bite from frustration.
Work with the childcare setting
If your toddler is biting at daycare, establish a
clear, consistent response plan with the childcare team. Consistency across
settings is essential.
Ask carers to log the time, situation, and people
involved each time biting occurs. Patterns often emerge quickly when biting is
tracked.
When does toddler biting stop?
Most toddler biting stops naturally between ages 2.5
and 3 as language improves and emotional regulation matures.
The timeline varies. Children who have good language
support and consistent, calm responses to biting tend to stop earlier. Children
with sensory needs may need longer-term support.
Licensed professional counsellor Lauren Mosback
advises: if biting becomes frequent, severe, or does not respond to supportive
strategies over time, professional support is appropriate.
Speak to your pediatrician if:
- Biting is increasing, not decreasing, after age 3
- It is causing serious injuries
- It occurs across multiple settings with no improvement
- It is accompanied by a significant language delay
- It is accompanied by other signs of developmental difficulty

People Also Ask
Why does my toddler bite?
The most common causes are limited language,
frustration, sensory seeking, excitement, and exploration of cause and effect.
Toddlers bite because they lack the language and impulse control to manage big
feelings any other way.
Is it normal for a 2-year-old to bite other children?
Yes. Biting is most common between 12 and 36 months. It
is not a sign of a deeply aggressive child. It is a developmental behaviour
that decreases as language and emotional regulation improve.
What should I do immediately when my toddler bites
someone?
Calmly address the child who was bitten first. Then
firmly and neutrally say to your toddler, "No biting, biting hurts” once.
Redirect to another activity. Avoid a large emotional reaction.
How do I stop my toddler from biting at daycare?
Work with carers to identify patterns by logging the time, situation, and people involved. Build a consistent response plan
for home and daycare. Address sensory needs, language gaps, and tiredness as
root causes.
When should I be worried about a toddler biting?
Speak to a pediatrician if biting is increasing after
age 3, causing serious injury, accompanied by language delay, or not improving
despite consistent strategies over several months.
