How do you talk to children about bodies and consent?
Early, using accurate words, and as an ordinary continuing conversation rather than one significant talk — which is what the safeguarding evidence supports, for reasons that are practical rather than ideological.
Why correct anatomical terms matter. Children who know the proper words can describe accurately what happened to them, which is directly relevant to disclosure and to investigations. Euphemisms create ambiguity at exactly the moment clarity is needed, and they also signal that these parts are shameful and not to be discussed — which is precisely what someone abusing a child relies on. Safeguarding organisations recommend accurate terms consistently.
What to teach, by stage:
Toddlers and preschool: names for body parts; that their body belongs to them; that nobody should look at or touch their private parts except to keep them clean and healthy, and that a doctor may need to with a trusted adult present; and that secrets about touching are never okay, which is the specific formulation that matters — the distinction between a surprise, which is temporary and happy, and a secret, which is permanent.
Early school age: that consent applies to them and to others; that they can say no to hugs and kisses from anyone, including relatives — which means adults must accept refusal rather than overriding it, since being forced to hug relatives teaches exactly the wrong lesson; and who their trusted adults are.
Later: privacy, online safety, changes at puberty before they begin, and that respecting someone's no is not optional.
How to say it well: answer at the level asked, briefly; do not react with alarm to a question, since reactions teach more than answers; use everyday moments rather than staging a discussion; and repeat, because one conversation is not retained.
The line that matters most: "you can always tell me anything, even if someone said not to, and you will not be in trouble."
If a child discloses something: stay calm, do not lead or question extensively, write down what was said in their words, and contact the relevant safeguarding service.
