Last Thursday, H worked at putting a rod inside a cylinder (two pieces from his cone sorting toy) for the first time. He was not successful, but it was clear that he had the concept of one piece fitting inside the other.
Last Friday, H turned the pages of Rainbow Fish Gift of Sharing, a soft book we’ve been reading for the past six months. He’s old hat at turning the pages of the board books we read, but he had never turned the pages of this soft book before. It was clear that he had generalized the concept of a book.
H is not the first to grasp these concepts, of course, but watching him in these moments feels like witnessing something extraordinary.
