Help the parent and teacher respond calmly, examine the observed context, and practise an acceptable alternative to biting across home and the early-years setting.
Respond calmly and set one clear limit
ZERO TO THREE explains that biting can be a way for a young child to cope with a challenge or meet a need, while the American Academy of Pediatrics notes that young children may still be learning self-control and ways to express anger with words. Both sources support a calm response that sets a clear limit instead of treating the incident as a reason to punish or shame the child. [2] [3]
Next step: Ask the teacher what happened immediately before the bite and what the adults observed, so the conversation begins with the situation rather than an assumed motive. [2]
- Use a firm, matter-of-fact boundary without anger or yelling, and keep it brief and clear. [2]
- Avoid calling the child a biter, shaming them, or relying on harsh punishment; ZERO TO THREE says those responses do not reduce toddler biting, and the AAP recommends calm limits over punishment. [2] [3]
Look for the situation that came before the bite
ZERO TO THREE gives several possible contexts for biting, including a strong feeling, a need for personal space, and oral stimulation. Its guidance is to investigate the observed setting rather than claim a single cause from one incident. [2]
Next step: Choose one age-appropriate alternative the child can practise, such as putting a need or strong feeling into words or getting an adult's help. [2] [3]
- Ask what happened right before the bite, who was involved, what the child was doing, where it occurred, and who was caring for the children. [2]
- Keep in close contact with the teacher and other caregivers so behavior can be monitored across settings instead of judged from one report alone. [3]
Use the same response at home and preschool
ZERO TO THREE recommends using the same words consistently after biting, while the AAP advises close contact with teachers and caregivers to monitor behavior and establish approaches that work both at home and away. The article should help the parent and teacher agree on one calm limit and one alternative behavior to reinforce. [2] [3]
Next step: If unusually aggressive behavior continues for more than a few weeks and the family cannot cope with it alone, contact the child's pediatrician for advice. [3]
What to do next: At the next conversation with the teacher, ask what happened before the bite, agree on one calm limit and one alternative behavior to practise at home and preschool, and keep in close contact about whether the response is helping. Seek pediatric advice if the behavior stays unusually aggressive for more than a few weeks and the family cannot cope alone. [2] [3]
- Agree on one short, calm limit that adults will use in both settings after a bite. [2] [3]
- Agree on the alternative behavior adults will prompt and praise, such as using words, asking for help, or stepping away from a conflict. [2] [3]
- Share observations regularly so the family and teacher can see whether the same approach is helping at home and in the early-years setting. [3]

Common questions
Does one bite mean preschool is wrong for my child?
One bite does not identify one cause. ZERO TO THREE describes several possible needs or challenges behind biting and recommends examining what happened before the incident, so the useful next step is to review the observed context with the teacher rather than treat one event as a complete readiness verdict. [2]
Should I punish my child for biting?
ZERO TO THREE says shaming and harsh punishment do not reduce toddler biting, and the AAP says young children respond better to clear, calm limits than punishment. Teach and practise an acceptable response instead. [2] [3]
When should I get more help for biting?
The AAP advises consulting a pediatrician when unusually aggressive behavior continues for more than a few weeks and the family cannot cope with it on its own. Keep the child's teacher and other caregivers involved so the behavior can be monitored across settings. [3]
