Tonight with your 9 to 12 year old
The prompt
“How much do you feel like you get to choose what you do before bed, and is that the right amount?”
What to listen for
If they have a clear opinion and can explain their reasoning, they're testing out having a voice in decisions that affect them, take the reasoning seriously even if you don't change the rule.
If they say it's totally unfair without specifics, they might need help turning a feeling into an actual request you could consider together.
If they say "I don't know," ask what they'd change about tonight's bedtime specifically, rather than the rule in general.
What this tells you
This tells you whether they feel like they have any real say over their own routines, or whether it all just happens to them.
