Understanding the sexual behaviour of children and young people

How to tell if a child’s sexual behaviour is appropriate for their age

We can help you understand whether a child’s sexual behaviour is expected for their age, or if it could harm them or other people.

Children pass through different stages of development as they grow. Each child is an individual and will develop in their own way. But there is a generally accepted range of behaviours linked to a child’s age and stage of development.

Take a look at our guides and find out how to:

• understand the sexual development of children under 5. You can also download a PDF in English or Welsh.
• understand the sexual development of children between 5 to 11. You can also download a PDF in English or Welsh.
• understand the sexual behaviour of teenagers: You can also download a PDF in English

If you are worried about a child’s sexual behaviour, offline or online, it is best to trust your gut and get advice. Speak to the non-judgemental experienced advisors on our confidential helpline. You don’t have to give your real name or details that identify you, and can stay anonymous. Call 0808 1000 900 for advice, support and information. If you’re not ready to speak to someone yet, you can use our live chat or secure email or look at the links below.
