I took one in but more to share a story about it with her than for comfort. I have brought in a wide variety of things in to share for different purposes. The one that was sort of more along you question was something I just so happened to have in my bag when I was having a really hard time. It is this ball that when squeezed blinks red, green, and blue lights for about 20 seconds. I used it to keep me present and calm down when I was very upset. I had asked for a moment so she was already sitting back observing me. She accepted it with little comment. What was said about using it was positive and supportive.

One time I ran into another client that had brought in a stuffed animal for support. I had the chance to talk to this other client. They disclosed they were going through a tough time and was using it for support. So, not that unusual I guess.
