I'm obsessed with a stuffed animal
What is it that you like so much about this stuffed animal?
I had a stuffed animal when I was young and I never lose him.
It's comforting to have an item that reminds you of your childhood. As long as it doesn't turn into an unhealthy obsession, take your comfort where you can.
I love Ken so much. His happiness keeps me going.
It is good that you named it. I think that it is okay to have a comfort item that you hang onto for a long time.
