Most children who are cyberbullied never tell an adult. The reasons are consistent across the research: shame, and fear that the phone or the account will be taken away. So the job of noticing falls to you, and the signs are usually behavioral rather than digital — a child who stops using a device they loved, hides the screen, or goes quiet at the wrong moments.
This guide walks through the patterns worth watching, how to tell bullying apart from ordinary peer friction, and what the first steps look like if your suspicion holds up. It is information, not medical or parenting advice; where the evidence is thin, we say so, and the final decisions about your child's devices and conversations remain the family's call.

What actually counts as cyberbullying?
The plain definition: Nemours KidsHealth describes cyberbullying as using technology to harass, threaten, embarrass, or target another person — on phones, computers, tablets, and gaming systems. Some of it is easy to spot, like a cruel text or comment your child shows you. Much of it is not: fake accounts, someone spreading a child's personal information, photos or videos shared to humiliate.
What makes the online version distinctive is persistence and reach. A child has near-constant access to their device, so the bullying follows them home and into the bedroom. And a single post can be copied and reshared, which means one cruel comment can take on a life of its own. The JED Foundation notes that more than half of U.S. teens have been bullied or harassed online, and that anonymity makes the behavior easier — people say things through a screen they would not say face to face.
One more thing worth knowing before you scan for symptoms: some children are at higher risk than others. Kids who learn and think differently are more likely to be targets, just as they are with in-person bullying, according to Understood — partly because social skills and friendships can be harder, and partly because other kids may see them as "different." The same source notes that girls, young women, and LGBTQIA+ teens and teens of color face elevated risk.
Which behavior changes should you watch for?
The signs cluster around the device, because the device is where the harm lives. Watch for a cluster of these rather than any single one — every child has an off week.
- Suddenly abandoning a favorite game or app, or wanting to stop using a device they previously enjoyed.
- Hiding the screen, turning the phone face-down, or closing out of apps whenever you walk into the room.
- Looking nervous or jumpy when a text, email, or notification arrives.
- Being unusually secretive or protective about their digital life, and dodging any conversation about what they do online.
- Withdrawing from family members, friends, and activities they used to care about; spending far more time alone in their room.
Offline echoes matter too. Nemours KidsHealth lists slipping grades, avoiding school or group gatherings, changes in mood, sleep, or appetite, and acting out in anger at home among the signs. Understood adds a telltale phrase to listen for: "there's a lot of drama at school," or "I have no friends." Those sentences are often an invitation to ask a better question.
None of these signs is proof. A moody twelve-year-old is also a normal twelve-year-old. What the sources converge on is the pattern: several changes at once, lasting more than a few days, and concentrated around the phone.
Why doesn't the child just say something?
This is the part parents misread most often, and it deserves a straight answer. Children stay silent for predictable reasons. They may not be sure what counts as cyberbullying in the first place. They may fear the standard parental response — confiscating the phone — which to a teenager feels like punishment for being hurt. Understood also observes that some kids tolerate negative attention from peers because any attention feels better than none. This connects to our earlier piece, Kids watch you scroll: modeling healthy phone habits.
There is a practical implication here, and it is one of the few things nearly every source agrees on: say explicitly, early and often, that if something ugly ever shows up on their phone, they will not lose the phone. If a child believes reporting means losing their social life, they will manage the problem alone, which is exactly what these situations punish.
How is this different from ordinary peer conflict?
Children squabble. They exclude each other for a week and make up by Friday. Bullying is different in kind, not just degree, and the distinction the experts draw is useful: bullying centers on a negative interaction that leaves the target feeling helpless — unable to make it stop. A rude comment from one classmate, once, is conflict. A pattern of messages, a fake account impersonating your child, a rumor spreading through a group chat they can't leave: that's the helplessness the definition describes.
Two questions help sort it. First, is there a power imbalance — anonymity, a group against one, someone your child can't push back on? Second, is it repeated, or does your child believe it will be? If the answer to either is yes, treat it as more than drama. The JED Foundation's self-check questions are a decent proxy for severity: is your child upset by the messages, hiding the screen out of shame, avoiding in-person social situations because of what's happening online, or withdrawing from friends and activities they love?
What should you actually do first?
Start with the conversation, not the confiscation. Nemours KidsHealth suggests opening by sharing a bullying experience from your own childhood, which makes the topic less loaded, and telling your child plainly that it is not their fault — bullying says more about the bully than the target. Praise them for telling you. Understood suggests that if a child resists, don't let it drop; calmly explain that keeping them safe is part of the job, and that you can look through the device together rather than alone.
Then, if the suspicion is confirmed, the sequence the sources recommend looks like this:
- Save the evidence. Screenshot the messages, texts, and posts before anything is deleted. Nemours KidsHealth notes these records can matter later — for the school, the other parents, or in serious cases the police.
- Don't retaliate. Encourage your child not to respond to the bully. Engaging tends to make things worse, and the JED Foundation advises disengaging if the behavior escalates.
- Block and report. Most devices and platforms let you block specific people, and reporting the account to the platform can get it restricted or removed.
- Notify the school. Tell a counselor, teacher, or principal. Many schools and districts have procedures for responding to cyberbullying, though they vary. Nemours KidsHealth recommends telling your child before you report, so you can agree on a plan together — being ambushed by your parents' intervention is its own injury.
- Escalate only as needed. If the bullying is intense, frequent, and nothing else works, Understood notes that involving law enforcement may become necessary, which is where the saved evidence earns its keep.
One caution on monitoring software: tools exist that flag language and report browsing history, and Nemours KidsHealth treats them as an option to weigh against your child's age and digital behavior — discussed with the child, not imposed in secret. Surveillance without consent tends to confirm the fear that made your child silent in the first place.
Our analysis: the quiet tell is the device itself
Reading across these three sources, the most reliable signal isn't any single behavior — it's a change in the child's relationship with the phone. A child being bullied online often stops treating the device as a toy and starts treating it as a threat. The game goes unplayed. The notification gets a flinch instead of a smile. Parents tend to watch what's on the screen; the evidence suggests watching how the child holds it.
What the evidence does not settle is how much monitoring any particular family should do, or when a school conversation becomes a legal one — those depend on your child, your district's policies, and your jurisdiction. What the research does establish is the cost of waiting: severe or persistent cyberbullying is linked to anxiety, depression, and trouble concentrating at school, per Nemours KidsHealth. Notice early, respond calmly, and keep the door open. Whether to hand over consequences, contact other parents, or involve professionals beyond the school is, honestly, your call — and the sources are careful not to pretend otherwise.
