i saw a trailer 或者 some thing on tv and it shows edward and bella with a three to five yer old girl with golden brown hair. Bella was stroking her hair and edward was smailing at her. and also in the 下一个 scene, jacob was 阅读 the girl a storybook the caption was " bella and edward spending time with there daughter." so guess she grows.... the girl looked like her
According to one of the trailers,Renesmee is gonna grow up and is gonna be an adult in only 9 to 11 years. I have read it somewhere. So I thought I should share it with 你 :)
If you're asking for book answer: Renesme will continue growing up until she looks as 17 years old. That's thanks to her human side. After that, she will stop growing up and she'll look 17 forever. That's thanks to her vampire side. That process will happen in 6-7 years.
