I have to admit that I found tenor the discussion regarding Wolfie's situation quite disturbing. I am fully aware that people have different opinions but why, oh why does everything have to be winners and losers? Wolfie is a small child who, by all reports, is well loved by his Mother, Father and Stepmother. Further, Beatrice seems to make a point of referring to him publicly as her stepson.
What on earth is the problem with that? While Wolfie's mother seems not to be the primary custodial parent she is, nonetheless, his mother and I have neither seen nor heard anyone dismissing her in any way and find that Beatrice's mother and father consider him their grandchild is no actual nor intended insult to Dara.
Kids make their own names for the people they love and great-grandparents and great-aunts and uncles are more and more common so kids sort it in their heads so it works and, in this case, Wolfie is what matters. Yes, Wolfie is part of two families, his father's and his mother's and he will sort that for himself.
However, I despise those who, in the name of political correctness would insist on "othering" him. To have Beatrice refer to him as her stepson and his biological half-sister or brother as her son or daughter is making him different. Basically, I have no problem with whatever Beatrice refers to him within the confines of the family because naming children differently can cause feelings of rejection and being second to the supposed "real" child.
It kind of like referring to your children as "these are my children A and B and my adopted/step child, C. Most blended families I am familiar with do not find the need to deal in steps or fractions. They just try to provide their children with love, support and security.
How exciting! Also, I did not expect to see a pregnancy announcement so soon after the marriage, and Bea did look "slim" at the funeral. I'm betting a October baby
