Family tensions are nothing new, but in today’s social media world, the drama often plays out online for everyone to see. One mom turned to Reddit after her sister-in-law repeatedly posted photos of her daughter, captioning them as though the child were her own.
It started with a premature birth announcement, escalated to a family photo with the caption “she calls me mama now,” and culminated in a Mother’s Day post that left the mom seeing red. Her cheeky response to the latest post set off a family firestorm and divided opinions on whether she handled it the right way.

Family dramas have a curious way of spilling onto social media, and OP’s story is a textbook case. At its core, the conflict isn’t about one photo, it’s about blurred boundaries, competing narratives of parenthood, and the loaded symbolism that captions carry online.
OP was understandably upset that her sister-in-law repeatedly framed her daughter in ways that implied maternal ownership: first with the birth announcement, then the “she calls me mama now” caption, and most recently with a Mother’s Day post. For OP, the sarcastic “I fixed it for you” photo edit was meant as a cheeky jab; for her brother and SIL, it was received as a public humiliation. Both reactions make sense — and both reveal deeper anxieties simmering beneath the surface.
From a psychological standpoint, it’s not unusual for extended family members to form close, even parental-like bonds with nieces or nephews. But the way those relationships are represented online matters.
Research has shown that social media conflicts about children, sometimes called “sharenting disputes”, are increasingly common. A UK survey by Nominet found that 42% of parents argued with relatives over posting pictures of children online. The fights weren’t about affection, but about control: who gets to define a child’s public identity.
Experts warn that captions like “she calls me mama now” cross a line because they shift from sharing a cute family moment to redefining parental roles.
Dr. Catherine Steiner-Adair, a clinical psychologist and author of The Big Disconnect, told The New York Times: “When parents don’t set boundaries about what’s shared, it can undermine trust and even distort a child’s sense of who is in charge of them”. OP’s discomfort, then, isn’t just pettiness, it’s a protective instinct about her daughter’s identity and relationship to her.
So what should OP do now that the relationship has escalated into blocking and angry messages? First, it may be wise to move the conflict off social media. Messaging or commenting back rarely cools tensions. Instead, a calm, private conversation with her brother, not the sister-in-law directly, may help establish boundaries.
For example: photos are fine, but captions suggesting parenthood are not. Second, OP should consider whether to limit her daughter’s unsupervised time in environments where these boundaries aren’t respected. Finally, therapy, though suggested as an insult by her SIL, could in fact be useful, not because OP is wrong, but because neutral third-party support helps untangle resentment before it deepens.
Here’s what Redditors had to say:
These Redditors called SIL’s behavior creepy, suggesting boundaries or protective orders



One commenter emphasized parents’ rights over children’s photos

Some users questioned SIL’s motives, seeking context on her daughter’s age


This group labeled SIL’s actions concerning, urging safety measures



One recommended talking to her brother

Another warned of potential danger


Finally OP provided an update in the comments




This situation struck a nerve because it touches on parental authority, identity, and respect. While some families see sharing children as a sign of closeness, this SIL’s captions clearly went beyond what OP could tolerate.
Was OP right to clap back publicly with her photo edit, or should she have taken a quieter approach? And how far would you go if a relative kept claiming your child online?
