Your child comes home and tells you, quite calmly, that someone took the thing and they let them. Or that they did not want to play the game and played it anyway.
And the advice everyone offers, "just tell them to stand up for themselves," turns out to be a sentence rather than a skill.
What the Kids edition teaches
Peanut has a friend who always wants her stuff. Her markers, her snack, her turn on the swing. Every time, Peanut says yes, even when she does not want to.
Slowly she starts to feel grumpy every time that friend comes around. The yes was supposed to keep her friend happy. It was making Peanut feel bad inside.
A lot of kids think saying no will ruin the friendship. Saying yes when you mean no just makes you grumpy, and that ruins it more.
The one move
You are allowed to say no, and to say stop
- Say it clear. Do not hope they figure it out. Say the actual no.
- Say it kind. You are not yelling, you are telling.
- Stop there. "No thanks" is a whole sentence.
The book's examples are deliberately plain: "No, I want to keep my markers today." "I don't want to share this one, sorry." And the one that matters most: "Stop, I don't like that," which it attaches explicitly to tickling, grabbing, or anything that does not feel good.
The part that happens at home
This is the uncomfortable bit, and it is the highest-leverage thing on this page.
A child learns whether their no counts by testing it on you. If "stop" during tickling reliably works, they learn that the word has power. If it is treated as part of the game, they learn that no is a thing adults decide about.
You cannot teach a child to hold a boundary with a peer while the same word is overridden at home for convenience.
This does not mean children get to decline everything. Bedtime is not negotiable. But there is a real difference between "you don't get to choose this" and "your no doesn't register," and children can tell them apart much earlier than we assume.
Why the short version works better
The instinct is to teach an elaborate script. The research points the other way.
Work on psychological reactance (Steindl et al., 2015) finds that restrictions arriving without a clear reason read as arbitrary, and arbitrary is what produces resistance. One true reason helps. Three do not, because a stacked justification signals that the limit is up for negotiation.
Frank Flynn and Vanessa Bohns (2008) add the other half. People substantially underestimate how willing others are to comply with direct requests. The plain version works far more often than the person making it expects, and this is as true at seven as at forty.
How to practise it without it becoming a lesson
Role-play the specific sentence
Not "be assertive." The actual words, out loud, for the actual situation they described. Children can produce a rehearsed sentence under pressure far more easily than an improvised one.
Catch the try, not the win
The Kids edition's guide for grown-ups is blunt about this: notice and name the effort. "You told him you didn't want to. That took guts." Whether it worked is not the part you are reinforcing.
Do not quiz them
Testing whether they used the move turns the whole thing into homework, which is the fastest way to kill it.
Let their no land on you sometimes
The most convincing evidence that no works is the one they collect at home.
Where this stops being about skills
Standing up for yourself is a reasonable frame for ordinary friction between children of roughly equal footing.
It is the wrong frame for bullying, and putting the responsibility on the child to handle it themselves is both ineffective and unfair. Repeated, targeted behaviour, especially with a power imbalance, needs adults to act. The Kids edition has a chapter for exactly this, "When It Feels Yucky, Tell a Grown-Up," and it frames telling an adult as the strong move rather than the last resort.
That distinction is worth making explicitly to your child, because otherwise "stand up for yourself" can read as "handle it alone."
Where to start
Take the specific thing that happened this week and write the one sentence they could have said. Practise it twice, in their words, not yours.
Then, the next time they tell you no about something genuinely optional, let it stand and say nothing about it. That is the lesson landing.
Common questions
How do I teach my child to say no to other kids?
Give them one short, specific sentence and rehearse it out loud for the actual situation, rather than teaching a general instruction to be assertive. A rehearsed line is far easier to produce under pressure than an improvised one.
Should my child give a reason when they say no?
One is plenty, and “no thanks” is a complete sentence on its own. Stacked reasons make a limit sound negotiable, and research on reactance finds that what mainly triggers pushback is a restriction that reads as arbitrary rather than one that is brief (Steindl et al., 2015).
Does letting my child say no to me undermine my authority?
Not if you separate the negotiable from the non-negotiable. Bedtime does not become a debate. But a child learns whether the word “stop” carries power by testing it at home, so overriding it during tickling or play teaches the opposite of what you are trying to teach.
What if it is actually bullying?
Then standing up for themselves is the wrong frame and it is unfair to put it on the child. Repeated, targeted behaviour, particularly with a power imbalance, needs adults to act, and telling an adult should be presented as the strong move rather than the last resort.
