The only people who I know that avoid their parents typically have pretty good reasons. Most of the people I talk to keep in touch. I see my mother, usually, every other week. We have had stretches though where we didn't see each other for a few months because everyone was too busy. I also see my in-laws about every other week too. My mother and I try to do fitness or art classes together so that we can meet up, do something interesting, and we usually go out for coffee or lunch after our class is over. She also wants to attend NAMI meetings with me. She wasn't always like that, but since I got pregnant, she has made a bigger effort to be a part of my life and wants to play a very active role in what will be her first grandchild's life as well. My in-laws don't have those same interests, but we do go out for dinner maybe 1-2 times a month to catch up with them. They also like to plan larger family vacations once a year so that everyone can spend time together.

The people I know who see their parents less than once a month hate seeing their parents usually because their parents are unpleasant, guilt-trip them, always ask for often complex favors, and they complicate their lives. When they go to visit, they don't do anything fun, they often just wind up sitting in the living room, which is not usually what they want to do. I know someone who stays as far away from her mother as she can because her mother tends to be kind of selfish, complains a lot, and when she comes to visit, actually makes messes in the house.

I don't know why your kids don't see you, it could be honestly that their lives are hectic at the moment, but you might also want to ask them if you are doing something that puts them off. It might be one way of trying to bridge that relationship so that you see everyone more regularly.
