I have shared your Grandchild a little bit...and be assured she is a winner.
its the ignored... left alone...made to feel a nusiance little ones who needs extra support.
Later in life if this attatchment stage has not been developed the grown child finds relationships of all kinds difficult..and may even cause the issue to go on to a new generation.

I watched a Grandmother is the waiting room of a hospital this morning..she held...had eye contact and was devoted to a tiny wee baby.This topping up of love...IS so beneficial.
You have shared and done all that and more within your family.
Material goods cant substitute...so its something money cant buy...
