Hi!
I love transitional objects! No shame in them, so long as it is for therapeutic value.
I have had former therapists give me a blanket, a plant, a card they fill out with writing, between sessions, etc.
I think they can become detrimental when your therapist becomes your abuser. This is a necessary boundary that very few people ever contemplate.
Attachment is dangerous. Be careful.
Thanks,
