What a fun thread, CoolCoco, thanks for starting it!
We have a few old items, like a bit box of Lego which still gets used. When the GC get bored, we have a timed round with a handful of pieces.
I also really like Mr. and Mrs. Potato Head. Somehow I have the urge to make sure they are put together before they go back in the toy box. Maybe that is influence from the Toy Story movies?
And I love adding to my arts and crafts box. My 8 yr old GD especially loves colouring and painting, so I will sit happily with her and create artworks,
