Yes definitely crossing boundaries here
I wouldn't even put my babies picture as my own profile so yes I agree she should change her photo I believe if you report it facebook can delete it
1000 % WRONG. ESSPECIALLY CONSIDERING the FACT that pedophiles gather content for their sick pleasure from family posts. There is programming that will even allow them to put your child’s face on a different body in porn . I don’t even post pictures of my kids on social media at all. Nobody else is permitted too either.
I hate it. My mil does that all the time.
I think it depends on your relationship with your MIL and the babies relationship as well. Is she really involved with the baby or is she one who likes people to think she is? Not posting your child’s face on Facebook? Have y’all asked people not to post a bunch of pictures of your child on Facebook and on their social media? Because if you have then, yeah I would be annoyed.
