In all honesty, I would not expect my son to give me anything. I did not adopt him as an investment to expect him to feed me in the future. If he wants to give me money, that's great. It's a bonus. And I would make it very clear that I would not be looking after his children because I do not believe that grandparents are to be grandchildren's primary caregiver. I would and have health insurance in place so that if and when we fall sick, my son will not be burdened by our medical bills.
