My suggestions may not work for you or your family. I no longer do gifts for my kids either. We all have everything we want or need as far as material things go.
Since we all live within about an hour of each other, I help them with their family. All three of my daughters and sons in law work. I pick up my older grands from school each day. They attend a private school and have no bus service. I also fill in on the days when their regular child care or school has or needs days off. I also help get the older grands to their games and practices during soccer season. My girls have a deep appreciation for this, much more than for any gift I could give them.
Maybe an IOU for keeping your grands when they have a need for it? Kind of a giving of yourself or your help to them.
