This is a tough one for me, so hopefully someone has some ideas.
We have a blended family with her oldest (23) and my oldest (20) already living on their own. My youngest (18) stays with me sporadically, seems like her friends take precedence, not really a problem.
Sunday dinners have always been a big deal. Her oldest comes for dinner, and mine do as well. Now it's only my youngest as my oldest lives too far away to make it.
The problem is with the conversation. It is almost completely monopoloized with her middle child (18) telling us her latest updates. It's almost like the dinner table is her facebook status page.
My youngest has told me she doesn't feel like coming for these dinners anymore as she is completely left out of the conversation. I have tried to steer the table talk to other topics of interest, but middle daughter immediately grabs the floor and makes it about her again. For what it's worth, this is a part of her personality, she does this with her friends as well.
Now I understand not everyone is a good conversationalist, but I do feel that somehow we need more of a balance. I hesitate to mention anything to my wife, as this would be a criticism of her daughters personality.
