Is the Goosebumps book series age appropriate for my eight year old?

Let her choose. ;) If she likes them, and is interested, let her. I began reading the goosebumps series when I was in the first grade, and I loved them throughout elementary school and read most of them since I loved reading books. I don't think they are too much for her, although she may not really enjoy them as some people don't.

Unless she is very easily scared, they should be fine. I loved them at that age. If she waits much longer to read them, she won't be that impressed. They are not that scary for an 11-12 year old.

they might be a little boring for her. maybe wait til she's in 3rd grade..that's about when I started reading them. Then again, I was 8, so. Maybe you should ask her if she wants to read them or not.

My nephew is 8.5 years old and he just started to read them.

Little too much. Horror films/stories/books just harness negative energy, definitely not something you want for your child.

Handing those books is like instiling fear into her.

Yes would be perfect

it's fine
