TG?

Help! I'm starting to *officially* homeschool in the fall. When my daughter was 1.5, she started talking. When she was 2 she wanted to read so I spent half a year going through Teach Your Child to Reading 100 Lessons. When she was three, I taught her to write. She's been reading every since I taught her so she's at a 2nd grade level right now. She reads every night by herself for an hour or two. She can't spell anything beyond the CVC pattern, so I'm going to be working on that, but I don't have readers because I don't know what to buy. I just got the Foundations B from Logic of English for spelling and handwriting work and don't know what to do to encourage reading/grammar but the readers are WAY to easy. Any thoughts??? (Also, is she smart or is she gifted?)
