I'm pondering the K issue too. A local private school takes gifted 4-year-olds for K, and I realized that's the last thing I want for Hanni (almost 4). I want to keep her in a play-based environment as long as possible, and then skip the whole K scene altogether.

Hanni is not an early reader, but she has the vocabulary and syntax and conceptual grasp of -- rough guess -- probably a 3rd or 4th grader. The whole "cat sat on the mat" thing is never going to be the right fit for her.
