The short version
- Grooming builds trust, then uses secrecy, gifts, and shame to control and exploit a child.
- Any single sign can be innocent. Watch for clusters of out-of-character changes, not one item on a list.
- Signs to notice: secrecy and screen-switching, unexplained gifts, withdrawal, mood swings, and sexual language beyond their age.
- Stay calm and reassure. Anger and confiscated phones teach a child to go quiet. Make clear it is not their fault.
- Keep evidence and report to NCMEC's CyberTipline at report.cybertip.org or 1-800-843-5678. Call 911 if a child is in immediate danger.
Grooming is when someone builds a relationship with a child to gain their trust and then uses that trust to abuse or exploit them. The NSPCC describes it as an offender "building a relationship with a child, and sometimes with their wider family, gaining their trust and a position of power over the child, in preparation for abuse." Online, it can start with something that looks harmless, a friendly message in a game or a supportive reply after a child posts that they feel low.
This is not rare. NCMEC's CyberTipline received more than 186,000 reports of online enticement in 2023, a category that includes grooming and sextortion, up more than 300 percent from 2021. Knowing the signs helps you notice early. But read the next part carefully, because it matters.
Any single sign can be innocent
Almost every warning sign of grooming overlaps with completely normal growing up. Teenagers get moody, want privacy, and stay up too late. StopItNow puts it plainly: some of these warning sign behaviors may be part of the normal growing up process or caused by other factors in a child's life. The point of knowing the signs is not to accuse your child or diagnose from one clue. It is to notice patterns, stay curious, and keep the conversation open. Look for clusters of changes and things that are out of character, not a single item on a checklist.
Signs worth paying attention to
Drawing on the NSPCC, eSafety, and StopItNow, here are changes that, especially together, are worth gentle attention.
In how they use devices
- Becoming secretive about what they do online, or quickly switching screens or hiding the screen when you come near.
- Spending a lot more time online, often late into the night, and becoming very possessive or agitated about their phone.
- Seeming upset, anxious, or withdrawn after being online.
In their relationships and behavior
- Talking vaguely about a "new friend," often older, without giving details.
- Having unexplained gifts, money, or gaming credits they will not explain the source of.
- Pulling away from existing friends, family, or activities, or going missing for longer periods.
In their mood and language
- Sudden mood changes, outbursts of anger, sadness, fear, or low self-esteem.
- Using sexual language or talking about things you would not expect them to know at their age.
- Changes in eating or sleeping, or a return to younger behaviors.
Groomers often work to create secrecy and isolation on purpose, because both make a child easier to control. The NSPCC notes that offenders may introduce "secrets," or use shame and blackmail, to stop a child from telling anyone. So a child who suddenly guards their online life and pulls away from trusted people is worth noticing, even though plenty of children do both for ordinary reasons.
Trust your gut, and stay calm
StopItNow encourages parents to trust that vague feeling that something just is not right, while remembering your child may be frightened too. If you are worried, the worst thing you can do is explode. Anger and confiscated phones teach a child to go quiet. A calm, supportive response keeps the door open.
Calm next steps if you are concerned
- Talk, gently. Ask open questions about their online friends and what they enjoy, without interrogating. Pick a low-pressure moment, like a walk or a car ride.
- Reassure, do not blame. If your child tells you something, the NSPCC advises reassuring them they did the right thing by telling you and making clear that whatever happened is not their fault. Grooming works through shame, so removing the shame is powerful.
- Keep the evidence. If something concerning has happened, do not delete messages or accounts. Screenshots and chat histories help if you report.
- Report it. In the United States, you can report online exploitation to NCMEC's CyberTipline at report.cybertip.org or 1-800-843-5678. Reports are reviewed by NCMEC staff before being referred to law enforcement, so this is a human process, not an automatic one. If a child is in immediate danger, call 911.
- Get support for yourself. You do not have to work this out alone. StopItNow's helpline and organizations like the NSPCC exist to talk parents through exactly these worries.
You know your child. If their online world has changed in ways that do not add up, you are allowed to ask questions and to ask for help. Noticing early, and responding calmly, is one of the most protective things a parent can do.
