Tonight with your 9 to 12 year old
The prompt
“Was there ever a time you gave someone else credit instead of taking it for yourself?”
What to listen for
If they can describe that moment, it shows a maturing sense of fairness, they're starting to value being honest about who did what over looking good themselves, which is a big developmental step.
Listen for whether it was easy or hard for them to do it, if it was hard, they need to hear clearly that you noticed the effort it took, not just the good outcome.
If they say they've never done this, you could ask if there was ever a time they wanted to but didn't, that honesty matters more than a tidy answer.
What this tells you
This shows how far along they are in valuing fairness over their own credit or image.
