Confused

Before I adopted I thought basically knew what I would tell Ella about her adoption. I believed in honesty always and still do. Saying that I now am faced with the hard facts of her adoption. How much information is too much? What is appropriate for other people to know including my own family? I know I wont have to answer hard questions for quite a few years with Ella, but I am constantly bombarded with questions now. I simply don't know what answers I should keep private and what is okay to share and with whom.
