AITA for wanting my mom to only babysit my kids and not my brother’s?
When OP’s father passed away, she (37) welcomed her mother (60) to live with her family, renovating their home to give her a private suite and covering her bills. In return, her mother watches OP’s kids (11 and 8) for a few hours after school each day. It’s been a win-win—until OP’s brother and sister-in-law (SIL) demanded that their mother also babysit their young kids (2 and 4), even sneaking them into OP’s house all day without asking.
When OP said no, her SIL unleashed a barrage of nasty messages, accusing her of favoritism and exploiting their mother. OP fired back, pointing out that her SIL, a stay-at-home mom, should care for her own kids. Is OP being too harsh, or is she right to protect her home? This story is bound to stir up opinions.

‘AITA for wanting my mom to only babysit my kids and not my brother’s?’
After her father’s death, OP welcomed her mother to live with her family and arranged childcare:


OP’s mother replaced the nanny, watching her kids under a clear agreement:



OP refused for several reasons, including the behavior of her SIL’s kids and inconvenience:




OP’s mother isn’t comfortable watching four kids, but SIL lashed out when told no:



OP clarified her stance, emphasizing SIL’s misuse of her home and mother:


OP’s decision to prevent her sister-in-law (SIL) from using her mother and home as a free daycare is entirely reasonable. The arrangement with her mother—providing a renovated living space and covering bills in exchange for part-time childcare for OP’s older children—is fair and mutually agreed upon. SIL’s unannounced drop-offs, without consulting OP or her mother, are disrespectful and place an unfair burden on OP’s mother, who has expressed discomfort with watching four children at once, especially toddlers requiring more supervision.
From SIL’s perspective, she might feel overwhelmed as a stay-at-home mom and see OP’s mother as a convenient resource. However, as psychologist Harriet Lerner notes, “Unclear communication in families can lead to unrealistic expectations” (The Dance of Connection, 2001). SIL’s failure to discuss her needs respectfully and her aggressive response to OP’s refusal reveal a lack of maturity. She’s entitled to seek support, but not by imposing on OP’s home or mother without consent.
The online community overwhelmingly supports OP, condemning SIL’s entitlement and highlighting that her role as a stay-at-home mom doesn’t absolve her of childcare responsibilities. Some suggest OP could be open to alternative arrangements, like her mother visiting SIL’s home, but SIL’s sneaky behavior and lack of communication make OP’s firm stance understandable. If SIL persists, it risks long-term strain on family ties, particularly with OP’s brother, who seems complicit.
OP should arrange a calm discussion with her brother, sidestepping direct confrontation with SIL, to clarify that their mother can visit their home to see their kids, but OP’s house isn’t a daycare. OP should encourage her mother to voice her discomfort directly, ensuring she isn’t pressured. If tensions escalate, a family mediation session with a neutral third party could help. Above all, OP must protect her home’s peace and her mother’s well-being, while striving to maintain a civil relationship with her brother if possible.

Some users asked for clarification to better understand the situation:

OP’s story is a classic tale of family boundaries and mutual respect—or the lack thereof. Her SIL’s sneaky drop-offs and demands for free childcare from OP’s mother are out of line, especially since the mother isn’t comfortable with it. OP’s firm stance protects her home and her mother, but the rift with her brother could widen without careful handling.
Is OP too strict in shutting down her SIL, or is she justified in drawing a line? How would you navigate this family drama? Share your thoughts below to keep the conversation going!
