Not in my household. Golden child was a sneaky, horrible, manipulative kid. My mum thought the sun shone out of her bum and is still proud to say my DSis was my 'mother', who always took me under her wing.
Reality was, she was always nipping me, controlling, belittling and domineering me, while my mum would be with her boyfriend/at the pub/not bothering with us. It made me a massive introvert and shy child, as I knew to speak up would backfire onto me and my mum would always protect her golden child.
Even as adults now, she's divided the family by singling me out and, knowing I back away from toxicity, she's glorifying in the limelight as being a perfect daughter while my mum still refuses to see how she really is. I even tried to show my mum a sequence of events as it was over texts and she refused to see it. Even in it, DSis was saying how stupid/worthless etc I am, yet I wasn't able to have the opportunity to prove that's how she's always spoken to me. As a result, I'm basically nc with DM unless it's a forced family event. My DC see her for what she is, from their own eyes, and as much as I try to keep all the cousins close enough, we'll never be a close, big family.
It's backfired on DM now though, I'm breaking the toxic chain and despite being told many times why I don't go to see her, she barely sees the GC either. The only time we really bother to see them, is when all siblings organise a meal or something. And even then DC and I sit at the far end of the table with the neutral siblings/nieces and leave those narcs at the other (boring) end.
