I did get Susan Winebrenner's book from the library and felt very overwhelmed. That all felt like to big of a job although I do like some of the ideas.
The ideas are very appealing - but really, that feeling you have of being overwhelmed should help you understand why so many kids have been grade or subject accelerated. It's really hard to do as she says without institution wide support. Yes the ideas are appealing - but no you shouldn't ask the teacher to do this for your kid!
The Yoga sounds like a great idea. Also, plain old 'deep breathing' has been helping me a lot lately.
Ask for the subject accelerations! Call and set up a meeting today. Really.
Grinity (yes - you guessed it: I do smile and grin alot!)
