Hello I believe I can help you with your concern
I definitely understand your concern for your grand-daughter's development in co-sleeping with her grandmother.
Most studies are mixed on this subject actually, but most find no harm in co-sleeping with a parent (most studies examine parent and child co-sleeping habits). Also at 6 years old, this is still considered acceptable and appropriate behavior for a child to sleep with a caregiver adult.
Here is an overlook article on the studies that have performed on this subject matter
So I would not be too concerned about this behavior, but I do believe that the 6 year old should be encouraged to sleep in her own bed and have her own independence at night. I think that is important for the child
Most studies only examine when a child and caregiver co-sleep as a result of the child being afraid and severe attachment issues and not wanting to be alone, so the child usually has their own bed in these studies.
THANK YOU THANK YOU I feel like a 1000 pound weight has been lifted from my shoulders.

I had been quite worried, but now I feel much better. Your answer is quite complete and I am glad that the studies are "mixed." Your answer is EXCELLENT FOR ME and it saves me a lot of unnecessary "grief," due to my not knowing a correct answer. I will tell my wife and she will be relieved.
