Should I let it go?

Im British so trying to hear it in an American accent and honestly it sounds like the same word 🫠 I would be pissed too tbf. I would suggest speaking to hubby about it and how much it's grinding your gears. Maybe if you're comfortable for it suggest they call her Nanny instead. Still close to mammy but far enough away for it to not be mummy. Honestly mammy sounds like a really southern kid saying mummy. I would totally speak to hubby about it

I really just wish our parents and in laws would just be okay being called grandma or grandpa. My dad and his wife want to be called Pappy and Gammo. My in-laws want to be Poppop and Kassii (gma in their native language) my mom and her wife want to be Nana and Nani.

It’s really up to you if you let it go or not, I wouldn’t but I would also say something and let it be known why I’m not okay with kiddo calling MIL something so close to Mommy. Your child doesn’t have to follow suit of their cousin.

The aw maaaaiin would annoy me because my kids not an entertainment source. You’re right it’s not malicious but in what world would a toddler say that 🙄
My sister tried to get my not even 2 yr old to “twerk” because she taught her 2 yr old how to shake her butt and I about ripped her head off, that shit is NOT cute. Our girls are 4months apart. Went off topic there sorry but ya no speak your mind if it’s bothering you girl!

Are they french ? I'm french speaking Belgian and common name for grandma is Mamie and grandpa is papi.

Same here! That’s how you say grandma in MIL’s language however I speak french and baby calls me mama/maman. I made it clear to dad from the beginning that he wasn’t going to call her that because it means mom to me and it’s how they’re going to call me. It wasn’t the first boundary we had to talk about (she took the no kissing and no posting on social media really hard) so she kind of just accepted that one easily! Took a couple nicknames to try out but we’ve settled on Nana!

Its a cultural thing i think. Im mexican and I called my grandparents Mami and papi. My mom was mommy, mother, momma. Same for dad. I dont mind if that what my mom wants to be called but thats because its a thing you know? Its whatever your comfortable with.
