On my Psychology Today blog on June 22, 2011, I re-posted an entryabout the huge increase in the number of grandparents raising their grandchildren since 1990, a trend which is continuing. Some of this is due to economic factors and military deployments, but in many cases, the “missing” parental generation consists of deadbeat parents who are addicts or alcoholics, those who exhibit signs of borderline personality disorder (BPD), or antisocial types who end up in jail.I discussed how, in my opinion, the grandchildren are being – covertly - given up to the grandparents as “gifts,” since the grandparents seem to exhibit a pathological need to continue to take care of children – even as they complain bitterly about how much they dislike having to do so.A completely different pattern of relationships between grandchildren and grandparents that I have been seeing more and more lately is the subject of today’s post: Parents who had been neglectful, abusive, generally unloving, or distancing towards their own children when those children were growing up seem to have a personality transplant when those children themselves have kids.They begin to dote on the grandchildren. They are warm and generous to them and have a very close and loving relationship with them. They tell them how much they love them, buy them things, and take them to various fun activities on weekends. In return, their grandchildren adore them, and usually think that their own parents must have been treated similarly when growing up by these wonderful, upstanding people. If the parents tell them differently, they may find it extremely hard if not impossible to believe.Such grandparents are giving the grandchildren everything that they did not give to their own children when their children were growing up.Imagine for a moment that you are the parent in the middle generation. Can you imagine how this would feel? On one hand, you know that you should be happy that your parents have apparently reformed their ways, and that your own children are getting from them all the things that you missed. On the other hand, however, your kids are getting from your parents everything that you wished you had received from them. You probably do not want to appear to be jealous of your own children, but why didn't you get that?What are you? The proverbial chopped liver? These contradictory feelings really can do a number on your head. Was it all your fault that you were treated badly? What have your kids got that you don’t?When patients in this predicament challenge their parents on this issue, the parents tend to get defensive or deny that there has been any sort of double standard at all. One such grandparent recently replied, "You already knew I love you! Why should I have had to tell you that?"So what might be happening here? My theory would predict that, as the grandparents are getting older, they are mellowing out, as people with personality disorders often (but hardly always) do. Theirown parents are often dying off as well, and are no longer feeding into their destructive behavior. So they start to have the relationship with their grandchildren that they might have preferred, had the family dynamics been different, to have had with their own kids.If and when their children confront them on the change, they go into attack or denial mode because down deep they feel horribly guilty and ashamed about their own behavior when their children were growing up. In fact, they are indirectly trying to atone for their sins with the grandkids. However, because they are guilty and ashamed of how they treated their own kids, they can’t face them, and push them away, similarly to the way other parents push their children away described in my post, Hatefulness as a Gift of Love.
