If you've read Breaking Dawn (and you should have!), Renesmee grows up real fast, being all half-vampire, half-human and all. Thus, the producers decide to have a few actresses play her.

6-year old actress Rachel St. Gelais has been confirmed to play a younger version of Renesmee Cullen in the fourth installment of the Twilight Saga: Breaking Dawn.

The actress’ official twitter account has confirmed that she is in Baton Rouge to film her scenes.
