Tonight with your 5 to 8 year old
The prompt
“If it were rainy all afternoon and you had the whole time totally to yourself, what would you want to do?”
What to listen for
If they choose something creative or imaginative, like drawing or building, they're showing a healthy comfort with their own inner world and enjoying their own company.
If they say they'd actually want you nearby even during "alone" time, that's worth noting warmly, it shows they associate feeling relaxed with having you close, even without needing constant interaction.
If they say "I don't know," ask what they did the last time they had free time like that.
What this tells you
This shows how comfortable they are with their own company and quiet time right now.
