AITA for not allowing my sister to stay with me for months, while she’s having her first child?
A woman and her husband, by choice not to have children, host their narcissistic sister abroad for over three months while she freezes her eggs. Now, the sister is planning to undergo in vitro fertilization (IVF) abroad to obtain a local passport for the baby, expecting to stay through the late stages of pregnancy, delivery, and the first weeks after birth. The couple fears invasion – invasion of privacy, frequent hospital visits, and forced caregiving between stressful jobs. Family relationships are strained when she receives free accommodation.
What complicates the story is that the sister’s single parenting due to an affair clashes with their right to privacy. Their attempts to have a child simultaneously highlight their different life paths, but her “convenience” ignores their limits. The knot lies in her history of selfish demands, which ultimately forces the host to say no.

‘AITA for not allowing my sister to stay with me for months, while she’s having her first child?’
Distant sisters rarely connect beyond holidays, clashing in personality.

An affair leads to fertility efforts requiring travel.




IVF shifts to birthing locally for passport perks.


Months with a newborn looms as intolerable.


Rights clash with autonomy when single parents expect free, indefinite housing from reluctant relatives. The sister’s plans create chaos before the birth, birth emergencies, and post-partum needs for a childless family, leading to the risk of resentment and marital tension. Parties are divided: those who support family obligations see refusal as cold, while those who support boundaries prioritize the peace of the host—especially when previous generosity is exploited. Society increasingly normalizes saying no to overreaching boundaries in adult sibling relationships.
Logistically, late pregnancy requires close proximity to care, but not at the expense of others; hotels or rental homes exist for a reason. Parallel life choices—childless or single motherhood—demand mutual respect.
“Hosting extended family during major transitions requires clear agreements; without them, goodwill erodes into obligation,” explains family therapist Dr. Laura Markham (2023). The company refused to protect the couple’s lifestyle, redirecting the sister to paid options or a support network at home.
Here’s what people had to say to OP:
Most users championed the no, citing hotels and past over-accommodation as proof of fairness.





A couple urged caution on risks, balancing empathy with practical shutdowns.









Witty voices added levity with entitlement jabs and rule reminders.





The couple’s firm no honors their childfree choice after prior generosity, while the sister’s convenience play ignores burdens. No villains emerge beyond mismatched expectations, but redirection to hotels preserves ties without sacrifice. Family support has limits.
