Maybe you could have a book to write AND draw in, or two books, one to write in, and another a coloring book for the littles to use?
Whomever is ready to start communicating, well, that's the beginning of co-consciousness. Some might be afraid that that means they won't be liked or they will have to go away. It's good to maybe write something about how nobody will have go away if you do this.
That's a good thing to put in a journal: who your T is, and how much you trust or like him/her, how you can get in touch with T and when you should.
I have to say nite nite now. Take care.
