It won't shock many that the new mom was not having it upon hearing her mother-in-law wanted her grandson to call her "mama."

"As if she's my son's mother," the poster blasted her MIL, going on to recount, "My partner and I told her 'no' because she's not his mum. So she decided to go and cry to my father-in-law about it saying it's not our place to tell them what they can and can't be called."

Unfortunately, tensions are still running high in this family after the new mom told her MIL that "mama" wouldn't fly as the name for her son to call his grandma.

A "screaming match" ensued over the name, instead of the grandma and mom reaching a compromise — although the original poster confided that when she's not around, the parents refer to the MIL as "Minnie" due to her love for Disney.

As always, commenters on the subreddit were more than happy to weigh in on the situation.

"This is your hill to die on," one supporter proclaimed. "There are many names she can go by. We chose an alternative name for my mother because she refused to be called a grandmother. Once your child starts talking, keep reinforcing the name 'Minnie' or whatever. This way, she can't get him to call her 'mama.'"

There's a bit more to the story, however, as the original poster soon shared in the comments section. Given an important detail about the family's living situation, does the grandma have a right to be called whatever she'd like?
