The in-laws are actually dh father and his second wife. Both have children from their 1st marriages but no children together. All children have families of their own.
Our DC have always known her as their grandmother, we don't say "step" and neither has she.. until now.
A message she send one of her friends popped up on my news feed, there was an exchange between them and she mentioned how she has x amount of grandchildren and x step grandchildren.
I just felt really hurt by the comments. We don't refer to her as step grandmother, just like we don't call her children "step sibling" or even their children "step cousins"
I am being unreasonable I know, but I'm feeling very hurt for my children. Like they are lesser in her eyes as they aren't her blood GC.
I wouldn't say anything to her or fil about it, or even dh, but just wanted to sound off about it.
