From the moment her parents divorced, a young girl was thrust into a role she never asked for—a surrogate mother to her infant sister. While her brothers were excused from responsibility, she bore the weight of constant caregiving, her childhood sacrificed to the demands of a fractured family where love was conditional and unfair expectations were imposed simply because of her gender.
In the quiet desperation of sleepless nights and silent resentments, she learned what it meant to be unseen and unheard. Her pleas for fairness were met with anger and blame, leaving scars that lingered long after the cries had stopped. This is a story of stolen childhoods, unbalanced burdens, and the painful journey to reclaim her own identity beyond the label of “Mommy #2.”
AITA for not caring for my sister?
According to developmental psychologist Dr. Ken Ginsburg, childhood should be characterized by opportunities for exploration, learning, and secure attachment, not by assuming adult-level responsibilities. The situation described strongly suggests the implementation of parentalization, where a child is forced into a parental role.
The mother’s behavior, including labeling the poster as “Mommy #2” and imposing caregiving duties based solely on gender (“maternal instincts just because I’m a girl”), demonstrates a significant boundary violation and inappropriate emotional labor transference. This pattern can lead to long-term resentment, identity confusion, and relationship difficulties for the poster, while simultaneously hindering the younger sister’s development of appropriate peer and parental relationships by conditioning her to rely on a sibling as a primary caregiver.
The poster is not selfish; they are reacting normally to an abnormal imposition of duties. The mother’s reliance on the poster to manage the younger child, especially during school nights and demanding shared resources (food, console), indicates poor co-parenting and an abdication of her own primary responsibilities. Constructively, the poster needs to establish firm, non-negotiable boundaries regarding caretaking time and resource sharing. If direct communication fails, involving a trusted third party, such as the father or another supportive relative, may be necessary to clearly define the limits of sibling assistance versus parental responsibility.

Your mom is the parent it is her responsibility to take care of her children not you if I was you I would ask to stay at my dad’s place more
The individual in this situation feels burdened by extensive, unpaid caregiving responsibilities imposed by their mother, specifically regarding their younger half-sister. A core conflict exists between the mother’s expectation that the poster act as a primary caregiver based on gender and the poster’s desire for normal adolescent life and autonomy.
Given the long-term imposition of roles exceeding that of an older sibling, is the poster acting selfishly by refusing to accept the mandated, constant caretaking duties, or is the mother being unfair by demanding this level of emotional and physical labor from a developing child?
