Older siblings who grew up in neglectful or abusive homes are often saddled with parenting duties long before they're ready.
Even if they're of legal age to care for siblings, the weight of filling in for an absent parent is heavy and hard to bear.
Sadly, this heavy weight extends multiple directions, as the younger siblings deal with the absence of their parent and the stand-in presence of a deeply stressed parentified sibling.
It can feel bittersweet to witness that sibling treat their own child differently later on, even if you understand why.
AITA for calling my sister for treating her child better than me?
My sister took my brothers and I in when we were just (4f 5m 6m) and she was only 19 at the time.
She did sacrifice a lot for us, including her boyfriend she's been with since she was 12 who broke up with her when he found out that she'd be applying for custody of us because he wasn't ready to take on such a responsibility.
