A three-year-old who tells another child they can't play is not a bully in the technical sense. They are an egocentric, socially developing person who has not yet learned to balance their preferences with somebody else's needs. A six-year-old who organises their friends to consistently exclude one specific child from lunch and break time is a different matter, and adults need to treat it differently.
The distinction matters for the response. Treating ordinary preschool unkindness as deliberate bullying creates problems of its own — anxious children who think they are wicked, exaggerated victim narratives in children who were left out for an afternoon. Dismissing genuine, persistent exclusion as "just kids being kids" fails the children who are being hurt. Reading the difference is part of the job.

What Bullying Actually Is
Bullying researchers define the term by three features: intentional harm, repeated over time, with a power imbalance between the children involved. A child who once trips another by accident is none of these things. A child who repeatedly calls the same child names, excludes them, or hits them — and chooses that child because they know they can get away with it — meets all three.
Most preschool and early-primary aggression doesn't tick all three boxes the way older-child bullying does, partly because the social cognition required for true bullying is still developing in three- and four-year-olds. A toddler grabbing a toy "because I want it" is not yet capable of the strategic, repeated cruelty that older bullying involves.
What preschool children do plenty of, however, is unkind behaviour, rough play that goes one-sided, social exclusion, name-calling, and physical aggression. These are worth addressing without needing the bullying label.
What It Looks Like in the Early Years
Social exclusion is the most common form: "You can't play with us." At two to three years this is usually about territory, routine, or a strong attachment to one particular friend, not a coordinated effort to harm. By five to six, deliberate and coordinated exclusion of the same child over time starts to become recognisable as targeted behaviour.
Physical aggression — hitting, pushing, biting (which usually fades as language comes in). When it is consistently directed at the same child rather than appearing in heated moments across many encounters, that's when concern is warranted.
Verbal unkindness — name-calling, teasing about appearance or family, mockery. Young children can be startlingly direct and cruel with words. Don't minimise the impact on the child receiving it just because the four-year-old saying it lacks the calculation an older child would have. The hurt is real either way.
Relational aggression — damaging someone's friendships, social manipulation ("I won't be your friend if you play with her") — is more common in girls and tends to emerge slightly later in development.
Responding When Your Child Is the Target
Take their experience seriously. "Just ignore it" and "they didn't mean it" tell a child that what felt awful didn't matter. It teaches them not to bring the next thing to you.
Talk to the setting. Teachers and nursery staff can observe what's actually happening, speak to the children involved, and make practical adjustments — proximity supervision at vulnerable times, structured activities that mix groupings, paired tasks that build new connections.
Coach social skills. Help your child rehearse assertive language ("Stop, I don't like that"), how to find a trusted adult, and scripts for joining play ("Can I play?") or moving on to another child if not.
Don't suggest physical retaliation. It reliably escalates rather than resolves, and it usually gets your child in trouble too.
Follow up. A pattern that continues over weeks despite the setting's intervention warrants a more formal meeting with the manager or SENCO.
Responding When Your Child Is Being Unkind
Resist the urge to be defensive. A parent whose child has been reported to be excluding others needs to take that on board, not bat it away. The setting telling you is a sign they trust you to help.
Talk at home, curiously, not punitively. "I heard you told Sam he couldn't play. That hurt Sam. What was happening for you?" Understanding what drove the behaviour — overwhelm, big feelings about a particular friend, copying something they saw — points to what to address.
Reinforce inclusion. Read books about it, model it in front of them, talk about how it feels to be left out. Empathy develops over years, not in one conversation.
The setting will manage the moment-to-moment, but consistent messaging at home that unkindness is not acceptable matters.
What Settings Should Be Doing
Preschools and schools should have a written behaviour and anti-bullying policy that all staff implement consistently — same response from every adult, so the child gets the same message wherever they turn.
Structured play (circle time, paired activities, organised outdoor games) reduces opportunities for exclusion and builds social skills across the group rather than only among children who would naturally pair up.
If you don't feel a setting is taking concerns seriously, escalate. The nursery manager or head teacher is the right next step.
Key Takeaways
True bullying, characterised by repeated intentional harm to someone in a less powerful position, requires a level of social understanding and deliberate intent that most children under five do not fully have. What parents and educators observe in early childhood settings is more accurately described as unkind behaviour, social exclusion, and early aggression, which is nonetheless important to address. Effective responses involve named adults, clear expectations, social skills coaching, and not minimising the child's experience. Children who are frequently excluded or hurt by peers in the early years should be supported both emotionally and practically, and a pattern of persistent victimisation should be taken seriously by settings and parents alike.
