11 Signs Your Child Is Being Bullied (And What to Do Today)

Most bullied children never tell their parents. The US Department of Education's most recent National Crime Victimization Survey found that fewer than half of students who experienced bullying at school reported it to a teacher or parent[1]. For cyberbullying, disclosure is even lower — Pew Research has documented that under one in three children tell a parent when they're targeted online[2]. The result is that parents often find out months after the bullying began, when symptoms are too clear to ignore.

The signs are knowable. Pediatricians, child psychologists, and bullying researchers have spent four decades cataloguing the behavioural and physical changes that show up in bullied kids. This article is the practical version of that research: eleven warning signs to watch for, the conversation framework that gets kids to open up, and a clear set of decisions for what to do once you know.

Why kids hide being bullied

Children don't tell parents about bullying for reasons that, taken individually, all sound rational from a 9-year-old's perspective. The literature consistently identifies several:

• Fear of retaliation. Telling an adult often feels — to the child — like making the situation worse. Olweus's foundational work documented that children worried that a parent's intervention would mark them as a "snitch" and increase the bullying[3].
• Shame and self-blame. Children frequently believe they did something to deserve the treatment. Research published in the Journal of Adolescent Health found that about 40 percent of bullied adolescents reported feeling at fault for the bullying[4].
• Loss of autonomy. Many children fear that disclosing will result in losing access to friends, social media, the school, or extracurricular activities — a punishment for them rather than for the bully.
• Belief that adults can't help. A 2017 study in Children and Youth Services Review found that children who had previously disclosed bullying and felt the adult response was inadequate were significantly less likely to disclose subsequent incidents[5].

None of these reasons are correctable through interrogation. They're correctable through observation — knowing what to look for so you can offer help before the child has to ask for it.

The 11 signs

These signs are drawn from the warning-signs guidance issued by the US Department of Health and Human Services through StopBullying.gov[6], the American Academy of Pediatrics policy statements on youth violence prevention[7], and the long-term outcome studies on bullying victimization conducted by Wolke and Lereya in the UK[8]. They are presented in the rough order in which they tend to appear.

1. Sleep changes

One of the earliest and most consistently documented signs. Bullied children often resist bedtime, take longer to fall asleep, wake repeatedly during the night, or have specific nightmares — frequently with school or social settings as the backdrop. Wolke's longitudinal research found sleep disturbance to be a near-universal early marker in chronically bullied children[8].

2. Mood changes — particularly Sunday-evening dread

Most bullied children show a mood shift that follows the school week. Sunday evenings, the night before school after a holiday, and the morning of any school day commonly produce irritability, withdrawal, or visible anxiety. The pattern is the diagnostic feature — a kid who is fine Saturday afternoon and grim Sunday night is signaling something.

3. Decreased academic performance

Bullying disrupts the cognitive resources kids need for learning. A meta-analysis published in JAMA Pediatrics covering 18 studies and over 75,000 children found a consistent association between bullying victimization and lower academic achievement, with effects independent of pre-existing ability[9]. A child whose grades drop without other explanation deserves a closer look.

4. Anxiety and increased physical complaints

Stomachaches, headaches, and unexplained fatigue — particularly clustered around school days — are classic somatic markers of bullying victimization in children. The mechanism is well-documented: chronic social stress activates the HPA-axis stress response, which produces real physical symptoms even when no underlying medical condition is present[10].

5. Depression-like symptoms

Brunstein-Klomek and colleagues' 2007 study in the Journal of the American Academy of Child and Adolescent Psychiatry established a clear dose-response relationship between bullying frequency and depressive symptoms in adolescents[11]. Children may show flat affect, loss of interest in previously enjoyed activities, expressions of hopelessness, or comments suggesting they feel worthless.

6. Withdrawal from social activities

A child who used to want friends over and now declines, or who suddenly gives up an extracurricular they previously loved, is signaling a social problem. Pay particular attention if the withdrawal targets one specific setting (one friend group, one practice, one bus route) — that's often where the bullying is occurring.

7. Appetite changes

Coming home unusually hungry can mean the child is avoiding the cafeteria — a known bullying hotspot. Skipping breakfast, refusing favourite foods, or showing visible weight changes also fit the pattern. The cafeteria specifically is documented as one of the highest-frequency bullying environments in school[6].

8. Reluctance or refusal to go to school

This is one of the more visible signs and one that often escalates fast. Frequent requests to stay home, last-minute illness on school days, missing the bus repeatedly, or asking to be picked up early — all warrant direct attention. School avoidance is the strongest single predictor of ongoing bullying victimization in younger children[12].

9. Lost, destroyed, or unexplained possessions

Missing lunch money, a torn jacket, a "lost" book, a broken phone case — repeated patterns of property loss or damage are often physical evidence of bullying that the child has explained away rather than disclosed. Single incidents are normal; recurring patterns are not.

10. Physical injuries

Bruises, scratches, or scrapes — particularly with vague or inconsistent explanations. The same applies to scratched-out classwork or torn assignments. By the time physical injuries appear, the bullying has typically been ongoing for some time.

11. Self-criticism and comments about being unwanted

Statements like "I'm stupid," "Nobody likes me," "I have no friends," or "I wish I wasn't born" — even when made in passing — should be taken seriously. The 2007 Brunstein-Klomek study found that bullying victimization in adolescents was associated with significantly elevated rates of suicidal ideation, with the relationship strongest in cases of chronic, frequent bullying[11]. Any expression of being unwanted or wanting to disappear deserves immediate, calm engagement.

Cyberbullying-specific signs

Online bullying produces its own behavioural signature, distinct from but often overlapping with in-person bullying[13]:

• Sudden, dramatic changes in screen time — either much more (compulsively checking) or much less (avoidance).
• Visible distress before, during, or after using a device.
• Hiding the screen, closing tabs quickly when a parent walks by.
• Suddenly deactivating or deleting social media accounts.
• Anger or sadness following specific notifications.
• Reluctance to attend school the day after intense online activity.

Cyberbullying disclosure rates are even lower than in-person disclosure. A combination of shame, fear of losing device privileges, and the perception that adults won't understand the platform all suppress reporting. Patchin and Hinduja's research at the Cyberbullying Research Center has consistently shown that children who feel they can talk to a parent about online incidents without being punished by losing internet access disclose significantly earlier and more often[13].

How to ask without making it worse

Direct interrogation rarely produces the truth. The conversation patterns that work are slower, less confrontational, and built on consistent, low-stakes prompts repeated over time. The framework below is drawn from the parent-mediated intervention literature, particularly Smith and colleagues' 2019 review in Pediatrics, which found that brief daily check-in conversations were the single intervention most associated with early disclosure of bullying[14].

The three questions framework

The point is not to have one big conversation. It's to make small ones routine. Three open questions, asked at low-pressure moments — at dinner, in the car, walking somewhere — create the channel.

• "How was your day, really?" — The "really" matters. It signals the parent wants more than the standard "fine." Don't ask in the first ten minutes after pickup, when most kids are still processing. Ask later, when the child is settled.
• "Did anything happen today that bothered you?" — Specific but gentle. Doesn't accuse, doesn't lead. Children often answer this honestly because it doesn't require them to label something as bullying.
• "Is there anyone at school you wish wasn't in your class?" — A peer-level question that often surfaces the people behind the situation.

The rules for the conversation

• If the child opens up, don't react visibly. Stay calm. The child is watching to see whether they made a mistake by telling.
• Don't promise to fix it. Promise to figure it out together. Premature promises break trust when they go unmet.
• Don't ask follow-up questions that feel like cross-examination. Let the story come out at the child's pace.
• Thank them for telling you. Explicitly. "I'm really glad you told me. That took something."

Repeat the three questions at low frequency — two or three times a week — for as long as needed. The channel staying open matters more than any individual conversation.

When to talk to the school, and when to let the child handle it

This is the question parents struggle with most. Acting too early can damage the child's autonomy and social standing. Acting too late lets the harm compound. The literature offers reasonably clear guidance.

Talk to the school when:

• There has been any physical injury — bruises, scratches, scars.
• The child is refusing to attend school.
• There is repeated property loss or destruction.
• The child is having repeated, specific nightmares about school events.
• There is any expression of self-harm or wishing not to exist.
• The child explicitly asks for adult intervention.
• The bullying has continued for more than two weeks despite the child's own attempts to handle it.

Let the child handle it (with support) when:

• The bully is roughly the same age and size as the child.
• There has been no physical injury.
• The child has a plan and feels confident about it.
• The situation is contained to one or two incidents and shows signs of resolving.

The middle position — actively coaching the child while not yet involving the school — is often the right one for two to three weeks. If the situation hasn't improved by then, escalate.

What most parents get wrong

Three patterns recur across the parental-response literature, and all three make bullying worse rather than better.

The "fight back" advice. Telling a child to "stand up to" or "fight" the bully without giving them the tools to do so safely produces a worse outcome in most cases. Untrained physical response in a school context typically results in the child being punished alongside or instead of the bully. The teaching that works is awareness, posture, and verbal de-escalation — physical defence only as a last resort, only after the other skills are practised.

The big-reaction conversation. When parents become visibly angry or upset upon hearing about bullying, the child often interprets the reaction as "telling Mom or Dad makes things worse." Subsequent disclosure shuts down. Calm engagement, even when difficult to maintain, keeps the channel open.

Going around the child to the school without warning. Children who learn that their parent contacted the school without their knowledge frequently report a permanent loss of trust around bullying disclosure. When school involvement is necessary, telling the child in advance — and where possible, including them in deciding what to share — preserves the relationship.

What to do today, in order

If you've recognised three or more signs in this article over the past two weeks, here is the order of operations.

1. Set up a low-pressure conversation tonight. Use one of the three open questions above. Don't push.
2. Watch the next 48 hours. Does the child volunteer anything? Do they look relieved or more closed-off?
3. Check the digital environment. With the child's knowledge, look at recent texts and social media activity for visible distress patterns.
4. Within a week, have a slightly more direct conversation. "I've noticed you seem worn out lately. Anything going on at school I should know about?"
5. If anything surfaces, do not promise to fix it immediately. Promise to think about it together.
6. If the criteria above for school involvement are met, contact the school — with the child's knowledge — within seven days.
7. Begin teaching response skills. Awareness, posture, verbal de-escalation, distance. The Cooper Color Code is a good starting framework.
