I agreed that grandparent should follow the wants of the parent in regards to how the child is looked after.

I do not agree that grandparents, in general, have any sort of responsibility to be there at the whim of their children. Expect no help from grandparents unless previously agreed before you get pregnant and then any help you do get is wonderful. The woman has taken the time to hand over her life schedule to show when she IS available. What if she wasn't retired? LW would not be able to make her change her work pattern. I think Amy did pretty well.
