Re: "Are you there God, it's me Margaret..." for an 8 yr old?
I loved that book as a kid!
I'm wracking my brain to see if I remember anything about it that would be bad. I guess the only thing would be if you're not ready to have the discussion about her period yet. Although some girls do get it as early as 8.
I think I would let her read it, might make it easier to break the ice on the bigger discussions in your future.
