How do you spot an adult who crosses boundaries with children?
Sources reviewed on November 1, 2026. Based on public advice, see below.
Watch behavior, not people. Stop It Now lists behaviors to take seriously: an adult who ignores a child's limits, keeps secret interactions, insists on time alone, or brings up sexual topics around children. One sign proves nothing, but it's a reason to speak up. Children shouldn't have to carry this. Adults should.
What should you watch for?
From Stop It Now, in its own words. Do you know an adult or older child who:
- refuses to let a child set their own limits, or uses teasing to keep a child from setting one?
- insists on hugging, touching, kissing, tickling or holding a child who doesn't want it?
- frequently walks in on children in the bathroom?
- has secret interactions with children, or spends a lot of time texting or calling them?
- insists on or manages to spend uninterrupted time alone with a child?
- seems too good to be true, for example by babysitting for free or giving gifts for no clear reason?
- tells sexual jokes, shows sexual images, or is overly interested in a child's body?
Why does this include family and friends?
Because CDC says about 90% of child sexual abuse is by someone known and trusted by the child or family. Nemours KidsHealth says most cases involve a close trusted adult or family member who abuses the child's trust. Most people you know are not a risk. The list is about behavior.
What do you do?
Stop It Now says starting a conversation is an important first step. Say what you saw, and what you want: "I noticed you tickle her after she says stop. In our family, stop means stop." And keep your child away from one-on-one time if you're unsure.

What if it's my own relative?
That's hard, and it's common for that reason. Talk to a counselor first if you want. Childhelp and the NSPCC take these calls, and you don't need proof.
I'm worried about my own thoughts. Is there help?
Yes. Stop It Now UK says its anonymous helpline is also for people worried about their own thoughts or behavior.
