Have you considered doll therapy when working with individuals with memory loss? This article lists the pros and cons. Overall, I think the benefits can be tremendous. I have observed elderly women in long-term care who talk to their doll and care for it. The doll is very comforting and provides great joy to the patient.
I just recently watched a documentary on adults- both men and women who are serious doll collectors (Barbie dolls and Reborn dolls) and they have no memory loss. Some women even bring their Reborn dolls out in public and push them in strollers.
I think it’s a great idea.
