A woman says she stopped babysitting her sister’s baby after being accused of trying to “replace” her as a mom. The 30-year-old explains she was thrilled to become an aunt and helped constantly after her sister gave birth — cooking meals, cleaning, and watching the baby so her sister could rest. But lately, her 27-year-old sister became distant and accused her of being “too attached” and “crossing emotional boundaries,” especially after the woman posted a picture of her niece online with the caption “my favorite little human.”
Hurt by the accusation, she decided not to babysit when her sister’s sitter canceled, saying she didn’t feel comfortable caring for a child when the parent doesn’t trust her. Her sister called her selfish and said she was abandoning her during a hard time. The woman argues she’s just respecting her sister’s boundaries, while her sister thinks she’s being petty.
AITA for not wanting to babysit my sister’s kid after she accused me of “trying to replace her”?
