Babbles,
We knew our DIL's rules and didn't knowingly contravene them. She always added before leaving, "Grammy's house, Grammy's rules to our GC. She'd wag her finger at our GS and warn, "Grammy and Grampa will tell me if you're naughty." I'd put on a stern expression and nod till his back was turned then I'd wink - at her.
When staying, with us at six years old, he'd complain about "all the bathing or showering I have to do, here."
Well. . .we found he'd just finished PT. He ran up distinctly sweaty and grubby, but happy, till we warned no TV first. It was always bath or shower, PJ's and home work before TV, then an evening meal.
My DH used to ask for his help in the kitchen. particularly making soup or porridge. Our GC had only eaten instant porridge
( and was delighted, when as a treat Gramps added a tablespoon of double cream onto his porridge for doing well in a test that day.
Babbles, really listen when asking his opinion. Find out if he and you share any activity in common or, ask him if he'd like to do any of the things that delighted you at his age. If giving out sweets ask why he likes it and ask for a description of its taste.
Make good memories, good luck and cheers
