Small, simple objects
My son played with his trains practically all day today.
As he rolls Thomas and friends along the tracks, he recites the words from his favorite episodes, mixing his favorite lines together to form a story of his own based on what tickles his fancy.
Small, simple objects that light up his imagination, create new storylines, and exercise his creativity.
We should all have small, simple objects in our lives that do that to us, no matter our age.
