How would wewe describe Rosalie's role in Renesmee's life and what kind of figure is she to Renesmee?

I see Rosalie as Renesmee's loving, doting aunt. :)
That little girl is most likely her world, along with Emmett.

I could see Rosalie as her protector, one of her four main role models (along with Alice, Bella, and Esme), and perhaps almost a sekunde mother. I mean, Renesmee is probably like the child Rosalie always wanted. She may not be her own child, but her presence alone is most likely enough to make Rosalie thrilled. :)

Aunt, Bella is her mother not Rosaile

Im think she is a mother figure, but Bella is Nessie's only mother and the only one...Rosalie is just her aunt who is very overprotective since she couldn't have kids herself

J think that she look at Renesmee like a mother and that she is too much protective
