i do not believe 11 is an appropriate age to read breaking dawn, but if you think your child is ready to read it, go ahead. i would say starting from age 12-13 and up is more of an appropriate age for breaking dawn.
On page 295 of Breaking Dawn is where they explain the immortal children. Or you can findthe answer in the back.
yes
for over twelves,yes
The second chapter of Breaking dawn.
yes read Breaking Dawn
Breaking dawn is acceptable IF you let the 11 year old read that kind of material and or read it first and decided yourself.
Yes, Bella has a daughter named Renesmee.
Yes, Bella and Edward can and do have children-a daughter called Renesmee in Breaking Dawn.
Breaking Dawn pt 2 has a few scenes that maybe bad for children to watch like when Edward and Bella have sex or when she gives birth but they wouldn't as bad if you were in the room with them
Breaking Dawn part one includes some scenes that are not appropriate. I would advise against it.
