Build in regular family time. This can be difficult as you grow older and have families of your own, but regardless of how hard it may be to schedule some face time, it’s an important part of maintaining that sibling bond, and passing on those priorities to your own kids. Whether you commit to regular holidays as a family, you plan a vacation together or you enjoy weekly family dinners, getting together to relive old memories and make new memories will help strengthen your sibling bond at any age.
