The individual, a 31-year-old male (OP), describes a strained relationship with his older sister (33f) due to fundamentally different life choices and beliefs regarding gender roles in marriage.
The sister, who adheres to traditional views, previously mocked the OP when his wife became the primary earner, and later expressed disapproval when the OP decided to become a stay-at-home father (SAHD). After the OP significantly reduced contact, the sister began requesting that he babysit her children, a request he denied due to her past disrespectful behavior, leading to conflict involving their mother.
AITA for telling my mom I don’t care if my kids never know my sister’s kids and I’m not going to take responsibility to teach my sister’s kids better?
As renowned family therapist Dr. Harriet Lerner states, “When we try to change other people, we almost always run into a wall of resistance. When we change ourselves, we often change the dynamics of the relationship.”
The OP is demonstrating a necessary act of self-protection by establishing clear, non-negotiable boundaries. His sister operates from a framework of traditional, rigid gender roles, which she projected negatively onto the OP’s successful marriage structure. Her current request for childcare is not based on mutual support but on exploiting the OP’s availability (due to his SAHD status) while simultaneously undermining his life choices. The attempt to use the children—suggesting the OP could ‘positively influence’ them or that his own children need cousins—is a form of emotional manipulation designed to override the boundary he previously set.
The OP’s decision to refuse the favor and protect his immediate family from exposure to the sister’s judgmental views is appropriate given the history of disrespect. A constructive future approach involves maintaining the current low-contact status until the sister can demonstrate genuine respect for the OP’s family structure. The responsibility for teaching the sister’s children better values rests primarily with their parents; the OP is not obligated to take on this educational labor or risk conflict within his own home to do so.

The central conflict revolves around the OP establishing firm boundaries against his sister’s attempts to leverage family relationships (specifically access to her children) to gain favors, directly opposing her judgmental attitude toward his lifestyle.
The core question is whether the OP is right to prioritize his family’s emotional safety and peace by refusing contact and the requested childcare, or if he should compromise and allow access to the nieces and nephews despite the known negative influence of the sister’s ideology.
