Am I Wrong For Setting Boundaries With My Sister Who Unexpectedly Moved In And Expects Full-Time Caregiving
AITA for refusing to keep being my sister’s full-time caregiver after she unexpectedly moved in with me? Read how Redditors weigh in on setting boundaries with a demanding sister and her baby.
A 26-year-old woman thought she was doing the right thing by helping her sister after a C-section. She expected a short, supportive window, like hospital time and the early weeks. What she did not expect was to become the default full-time baby staff the second her sister moved into her home.
Her sister, 21, moved in “temporarily” because her husband works nights and needs to sleep during the day. The catch is that the sister is relying on OP to handle most of the feeding, diaper changes, soothing, and general baby care, while OP is also trying to work and function on almost no sleep.
Now OP is setting boundaries, and her sister is calling her a bad person for refusing to keep doing everything, so the real question is whether she was trapped into the role in the first place.
Original Post
My sister (21f) had a baby almost two months ago via c-section, and I (26f) have been helping a lot. I work with kids often, but I don’t have or want any of my own.
Since I have experience, my sister keeps saying I should be the one to help since I “know what I’m doing.” I understood she would need extra support while recovering, so I stepped in to help during the hospital stay and the first few weeks. However, I was caught off guard when she unexpectedly moved in with me. She said it was because my brother-in-law works nights and needs to sleep during the day, so staying with me would make things easier.
I completely understand that she’s recovering and exhausted, and I don’t blame her for needing help. But I wasn’t expecting to take on this much responsibility.
For weeks now, I’ve been the one handling most of the feeding, diaper changes, soothing, and general care. Meanwhile, my brother-in-law gets to sleep all night and all day, and my sister while struggling relies on me for almost everything.
I’m barely getting any sleep myself while also trying to keep up with work and other commitments. The thing is, this was a planned pregnancy.
I can’t help but wonder if they really thought about what care would look like once the baby arrived because, from my perspective, it feels like I was always meant to be the fallback option without ever being asked. When my sister was pregnant, I warned her that a baby is a lot of work and that she was rushing into it with someone she barely knew. I have a job and other responsibilities that usually fill up my entire week.
Now that I’ve started setting boundaries and stepping back from doing everything, my sister is upset and saying I’m a bad person for not wanting to help more. I feel bad, but I never agreed to this level of involvement.
AITA for refusing to keep being my sister’s full-time caregiver and setting boundaries?
Establishing boundaries is essential for maintaining healthy relationships, particularly when family dynamics become complicated. In this scenario, the unexpected move of a sister seeking full-time caregiving support can easily lead to feelings of overwhelm for the caregiver.
The importance of self-care cannot be overstated in this situation. This delicate balance is crucial, especially when the demands of caregiving can quickly become all-consuming.

OP stepped in right after the hospital stay, but the moment her sister moved in, the “help” turned into her doing nearly all the baby work every day.
Research published in the Journal of Family Psychology indicates that individuals who set and maintain boundaries report higher levels of satisfaction in relationships. This is particularly pertinent for caregivers who may feel obligated to sacrifice their own needs for family members.
Finding this balance is essential to avoid resentment and emotional exhaustion.

While the brother-in-law gets to sleep all night and all day, OP is the one stuck feeding, changing diapers, and soothing the baby nonstop.
This also echoes a couple’s fitness plan, where one partner secretly breaks the diet.
In the narrative of setting boundaries with a sister who has unexpectedly moved in, guilt emerges as a significant emotional hurdle. The protagonist faces the challenge of balancing familial obligations with personal well-being, a dynamic that often leads caregivers to overlook their own needs. The article highlights that while the instinct to help is commendable, it can spiral into a cycle of resentment and burnout if boundaries are not established early on.
This situation illustrates the critical importance of recognizing the risks associated with unchecked guilt. The protagonist's realization that caregiving should not come at the expense of their own health is a pivotal moment in the story.

OP even warned her sister before the baby arrived that having a newborn is a lot of work, but now that she’s backing off, her sister is upset and guilt-tripping her.
Practical recommendations for caregivers include developing a self-care plan that prioritizes their own needs alongside those of their family. Research suggests that engaging in regular self-reflection and establishing a support network can mitigate feelings of guilt and promote healthier boundaries.
Additionally, seeking professional counseling can provide caregivers with tools to navigate these complex emotional landscapes and reinforce their boundaries effectively.

The conflict boils down to this, OP says she never agreed to full-time caregiving, and her sister says that makes her a bad person.

In the context of the article, the need for boundaries becomes a central theme in navigating the complexities of family dynamics. OP's situation highlights that setting limits is essential not only for personal well-being but also for maintaining a supportive environment. The dilemma of providing full-time caregiving while feeling overwhelmed underscores the importance of self-care in caregiving roles.
Without personal space and time to recharge, caregivers may find it challenging to offer the compassion and support their loved ones need. OP's decision to establish boundaries is a crucial step toward ensuring that both her needs and her sister's can be met in a balanced way.
Nobody should get stuck caring for a newborn like it’s their job when they never signed up.
