'There's only one momma in his life, and that's me': New mom stands firm against mother-in-law after she teaches grandson to call her "momma"

Names and nicknames carry a lot of meanings in families. They can hold warmth, history, or a sense of belonging; A grandmother called "Yaya" could hint at Greek ancestry, and a grandmother referred to as "Meemaw" may strongly suggest Southern origins. But names can also be a cause of tension. In many families, the titles we use define who's who in the family's circle of love and authority. In my family, for example, I call my grandmother "Mama + her name," a sweet and familiar tradition that feels comforting and earned. But not every grandmother deserves to carry this title. 

One new mom recently found herself in an uncomfortable situation when her mother-in-law, who has a history of making subtle digs and backhanded comments, decided that she wanted to be called "Mama Cornelia" by her grandson instead of the agreed-upon "MaCo." At first, the mom tried to shrug it off, but when her toddler actually started using the name, it just felt wrong. Because while "Mama" might seem like just another title, to this new mom, it felt like her mother-in-law was claiming a role that wasn't hers.

    AITA for not wanting my son to call my mother-in- law "momma"?

    Hi everyone, I (29F) have been with my husband (34M) for 9 years. My relationship with my MIL (let's call her Cornelia) has never been great. On the surface

    she's polite and diplomatic, but she has this way of making little digs at me, always subtle enough that outsiders wouldn't notice unless they knew me well.

  • So, I do call my grandmother Mama, but she never made digs at my mom or called me trashy nicknames, so I think my grandma deserves that monicker!

    MaCo anymore, he was calling her Mama Cornelia. This really bothers me. To me, there's only one Momma in his life, and that's me.

    bokatan 778 NTA. Start referring to her as "granny" at home. Also, your husband is an AH here for not having your back.

  • It's a shame because MaCo is actually so adorable! But now she must be Granny forever.

    FraggleBiologist Agreed. She knew your feelings. Now you stop playing nice. You AND your husband are letting her walk all over you.

    She's granny now, every single time. In front of her, at home, never say her name again. Even when talking to your husband or other family members, she's Granny. Permanently.

    Putrid_Magi My own mother wanted to be called "Mini Mom", because she's small in stature. Turns out she was insane.

    SHUT. IT. DOWN. NOW. Grandma is a perfectly acceptable moniker for a grandmother.

    miss_sassypants I was thinking maybe if MIL wants to be Momma they could train him to call her Big Momma.
