Now I know no one should get annoyed about Facebook stuff. My DHs step brother and his gf just got their first dog. DHs step mum posted a photo of said dog on Facebook saying “my first grandchild ❤️”. She’s not remotely tongue and cheek person so I know it wasn’t meant like that, she is also very much a dog person and would genuinely consider a dog a “child”. She’s been his step mum for nearly 30 years so she’s not exactly a new addition to the family and we are all close.
Not to mention the fact me and DH have previously had a dog - we also have a baby who she has always referred to (at least in front of us) as her grandchild.
I understand that she will probably feel more strongly about her biological grandchildren if / when they arrive but... a dog? And on a forum where she knew we would see it?
Are me and DH BU to annoyed about this?
