Split Families

I have two grandsons. Each one is the only biological cousin to the other. My older grandson has parents who are divorced.  His mother is my younger son's former wife. They have legal joint custody on paper, but in fact, my son's ex-wife takes complete control over decisions. On paper, they are supposed to share visitation on major holidays like Christmas, but in fact, we have not seen our grandson for a major holiday since Thanksgiving of 2014.  As a result, he has not seen his younger, and only, cousin in more than a year.  Until my son can take her back to court and force her to change the way she treats him and their son, this is likely to continue. She seems to go out of her way to deny our grandson the opportunity to share celebrations with his father's family, and to get to know his paternal blood relatives. She also changes plans at the last minute, and never seems to be able to make a definite commitment as to pick-up time until the morning of, often resulting is disruption to our schedule and/or our plans.  She did it again today, which is Christmas Day, when our son was supposed to pick up his son at noon.  Suddenly, she needs to have their son with her as she travels from place to place today, and now my son can't pick up his son until this evening, when Christmas is virtually over and the rest of our family is gone. The boy again has missed another chance to see his cousin, as that family comes to us on Christmas Eve, and leaves on Christmas Day to go to my daughter-in-law's family.  2016 is a Leap Year, meaning that the next Christmas will fall on a Sunday. If the planning goes right, my son will have his son on that weekend. Then we may finally get the celebration we have been wishing for. One can only hope.
