Tonight with your 5 to 8 year old
The prompt
“If you got to build an obstacle course in the living room right now, what would it include?”
What to listen for
If they plan something elaborate with pillows, tunnels, and challenges, they're showing you how much they enjoy building a world and then testing themselves inside it.
If they want you or a sibling to try it too, that's them wanting an audience or a partner for the fun, not just solo bragging rights.
If they say "I don't know," start simple, "okay, first obstacle: what do we jump over?", and build it step by step together.
What this tells you
How elaborately they design the course shows how much they enjoy creating a challenge for themselves and sharing it with others.
