What odd ideas of family some people have. Whilst I totally agree that this grandmother should tread carefully or she may also be excluded, I think family means all members, including grandparents. Grandparents are not an add on extra if the parents feel magnanimous enough. Grandparents are a wonderful help and support to parents and their children, and yes, I think they are vital. I adored my grandparents, I only had two because the others died, but they were an integral part of my family and my growing up. They enriched my life and I thank God I had them and that my parents would no more have felt the need to control them by ‘allowing’ access as and when they felt like it that they would have thought of flying to the moon. Grandparents should be integral to the family and mine were. When we were in New Zealand recently and had almost complete care of our grandchildren in order to help their mother, our daughter, as her marriage disintegrated, the school told us how valuable we had been at such a difficult time for our beloved grandchildren by providing stability for them. The children love us to bits and we them. This woman is controlling her husband for God knows what reason and she is depriving her child of his grandfather because she can, and that’s just plain nasty in my opinion. Nonetheless this OP has no choice to obey, note the word obey, because that’s what she needs to do, if she wants to continue to see her grandchild. It is nasty when parents, usually in laws it seems, decide to use their children in this nasty and controlling way.
