Things are easy when your adult kids are single. They can always (well, usually) make time for you. They can come home for major holidays and go on vacations with the rest of the gang. But once they have families of their own, there are going to be scheduling conflicts. There might be fewer family dinners, and maybe Christmas at your house will happen only every other year. Try to be understanding about this, and don't make your children feel they have to choose. They need time to create their own family traditions.
