Re: going full time
The key question is, why did you retire? If the answer is that you wanted to become a babysitter, then it looks as though you have been a success. But if you did so to enjoy your life, it is time to get started!
We have been full-time now for eight years and we don't spend a great deal of time at the kids homes but we manage to be special people in the grandkids lives anyway. We take them out with us in our RV for time away from the rest of the family. Once grandchild at a time. When they reach years they then can fly to where we are and each of ours get to do that for a week or two, every couple of years. In that way, we have truly quality time with each one and they do not have to compete with even their own parents for our time.
