The call from school is specific and urgent: your five-year-old hit a classmate during circle time, or bit another child on the playground. An incident report is coming home. A meeting has been scheduled. For most parents, the first instinct is a mix of embarrassment and fear, a sense that something must be deeply wrong with their child or with their parenting.
But kindergarten-age aggression is more common than many families realize. According to the National Association for the Education of Young Children (NAEYC), biting and hitting in early childhood are typically driven by frustration, sensory overload or underdeveloped communication skills, not by malice. The behavior is a signal. The school meeting is a chance to decode it. Here is how to walk in prepared and walk out with a real plan.
Why a five-year-old hits and bites at school
At five, most children are still building the neural wiring for impulse control. The prefrontal cortex, the brain region responsible for pausing before acting, does not fully mature until the mid-twenties, and at kindergarten age it is especially raw. That biological reality means a child who feels cornered, overstimulated or unable to express a need may default to physical responses.
Occupational therapists at Griffin OT describe hitting and biting as “forms of communication,” noting that these behaviors often appear when a child “does not yet have sufficient social communication skills” to express discomfort another way. Their clinical guidance emphasizes that when adults address sensory needs and social communication gaps alongside clear behavioral boundaries, aggressive incidents typically decrease.
That framing matters for parents heading into a school meeting. If the conversation starts with “your child is aggressive,” it helps to reframe internally: my child is struggling to communicate something, and we need to figure out what.
What the behavior may actually be telling you
Not all hitting looks the same, and the trigger behind it changes the response. The NAEYC identifies several common drivers: a child might bite to cope with frustration, to manage overwhelming sensory input, to seek attention or to regain a sense of control in an unpredictable situation. Their guidance notes that as “children mature, gain self-control, and develop problem-solving skills,” most outgrow biting, but stresses that adults play an active role by “calmly interrupting the bite, naming the feeling, and offering another way to respond.”
However, biting that persists past age three or four, or hitting that escalates in frequency at five, can sometimes point to something beyond a developmental lag. The American Academy of Pediatrics recommends that parents talk with their child’s pediatrician if aggressive behavior is frequent, intense or does not improve with consistent intervention. Conditions such as sensory processing differences, anxiety disorders, ADHD or speech and language delays can all amplify physical outbursts in a classroom setting, and early identification leads to better outcomes.
Parents should not panic at the mention of evaluation. A referral is not a diagnosis; it is a way to rule things in or out so the right supports land in the right place.
How to prepare for the school meeting
Walking into a behavior meeting without preparation puts parents at a disadvantage. The instinct to apologize or to defend can take over, and neither moves the conversation toward solutions.
Clinical psychologist Dr. Jazmine McCoy, who writes at The Mom Psychologist, recommends that parents arrive with structured questions rather than emotional reactions. Her framework focuses on gathering facts first: What exactly happened? What led up to it? What did the adults do afterward? What has worked on days when the behavior did not occur?
Before the meeting, it also helps to:
- Write down what you observe at home. Does your child have meltdowns after school? Do they talk about specific stressors like noise, a particular peer or transitions between activities?
- Request any data the school has collected. Ask for frequency counts, time-of-day patterns and descriptions of what happened immediately before and after each incident.
- Know your rights. Under the Individuals with Disabilities Education Act (IDEA), parents can request a formal evaluation at any time if they suspect a disability is contributing to behavior. The school must respond to that request in writing, and the evaluation is free.
Showing up with notes and specific questions signals to the school team that you are a collaborator, not a bystander.
Questions that reveal what is really happening in the classroom
The most productive questions focus on context and function, not just how many times a child hit someone this week. Consider asking:
- “What is happening in the five minutes before each incident?” This targets antecedents: transitions, unstructured time, specific academic demands or peer conflicts.
- “Where and when does the behavior tend to happen?” Aggression clustered at recess or during loud group activities may point to sensory overload. Aggression during writing time may signal frustration with fine motor tasks.
- “What does my child gain or avoid by hitting or biting?” This is the core question of a functional behavior assessment (FBA). If hitting gets the child removed from an overwhelming activity, the behavior is serving a purpose, and the intervention needs to address that purpose, not just punish the action.
- “Has the school conducted or would it be willing to conduct a functional behavior assessment?” An FBA is a structured observation process, often led by a school psychologist, that identifies triggers and patterns. Parents can formally request one.
- “What strategies are staff using to prevent incidents, and what alternatives are being taught?” Look for proactive measures: a calm-down corner, visual schedules, social stories, pre-teaching expected behavior before transitions.
- “How will we communicate about progress between meetings?” A daily or weekly check-in system (even a simple color-coded chart sent home) prevents the next conversation from being another crisis meeting.
If the school’s answers are vague or focus only on consequences (“we told him to stop,” “she lost recess”), that is a sign to push for a more structured support plan.
What about suspension and expulsion?
Many parents do not realize that exclusionary discipline is used even in kindergarten. A 2023 report from the American Civil Liberties Union found that preschool and kindergarten suspensions disproportionately affect Black children and children with disabilities. Research consistently shows that suspending young children does not reduce aggression and can worsen outcomes by disrupting attachment and routine.
If the school raises suspension, parents should ask whether all other interventions have been tried first and whether the child has been evaluated for a disability. Under IDEA, a child with a suspected or identified disability has additional protections, including the right to a manifestation determination before a suspension longer than ten days.
What parents can do at home
School may be where the behavior surfaces, but home is where many of the replacement skills take root.
The Triple P (Positive Parenting Program), an evidence-based program used in over 25 countries, recommends several concrete strategies for families dealing with aggression in young children:
- Name emotions in real time. “Your fists are clenched and your face is red. That looks like anger.” Connecting feelings to body sensations builds the vocabulary children need to replace physical reactions with words.
- Coach a break before the explosion. Practice a simple routine when everyone is calm: “When I feel my body getting hot, I can go to my cool-down spot.” Rehearse it like a fire drill so it becomes automatic.
- Role-play alternatives. Use stuffed animals or puppets to act out scenarios: “Bear wants the truck but Lion is using it. What can Bear say?” Repetition in low-stakes moments builds the scripts children draw on under stress.
For children with sensory needs, Griffin OT recommends pairing behavioral expectations with physical supports: movement breaks, fidget tools, changes in seating and collaboration with a speech-language pathologist if verbal expression is a barrier. Parents can mirror these at home with activities like jumping on a mini trampoline before homework, using a weighted lap pad during screen time or practicing short phrases for asking for space (“I need a break, please”).
When to seek outside help
If hitting and biting continue despite consistent strategies at home and school, or if the behavior is intensifying, it is time to loop in professionals beyond the classroom. A developmental pediatrician, child psychologist or board-certified behavior analyst (BCBA) can conduct a thorough assessment and rule out or identify conditions that require targeted treatment.
Parents should not wait for the school to suggest this. Pediatricians can make referrals, and in many states, families can self-refer to their local early intervention or school-age special education office for an evaluation.
The goal is not to label a five-year-old. It is to make sure the adults around that child understand what is happening well enough to help.
