I'm not really concerned about the toy thing being an obsession. I do feel it's similar to what
@BG1 said about it being a comfort. Yes, she has it with her a lot. But there's also times when I'm outside and she is playing with her rope or taking a short walk with me, without the toy. So I don't feel like it's a real obsession. It's just that it's different than what we've seen in the past.
