Renesmee's diet in Breaking Dawn is mostly blood even though she can eat human food. She prefers blood and Carlisle tried to get her to take the baby formula in the book but she didn't have much patience for it. :)
Yes.
Her name is Mackenzie and shes really pritty
Actually present at Renesmee's birth were Jacob, Edward and obviously Bella.
She was born on the 10th September 2006
No. She says that the vampire scent is enough to keep her from wanting Renessmee's blood.
Renesmee's teeth are special because they are that of a vampire's, although she is half vampire and half human.
I am a little confused by this...do you mean how long they have been Vampires or what place they are in the family. Carlisle is the oldest then: Jasper, Edward (i think), Alice (or Esme), Esme (or Alice), Roselle, Emmett, Bella and Reenesme.
She ages much faster than a normal human, but she will eventually stop aging around the age of 17-19
The Cullen family (Edward's family) and Tanya's family the Denali.
well on renesmess locket it says "More than my own life."
Jasper. He is the newest Vampire and not quite accustomed to the "Vegetarian" diet.
In Breaking Dawn, when Edward learned that Renesemee could hear within Bella, he started to hum Bella's lullaby to her. That ends up being her favorite song.
