Yep. Asynchrony IS giftedness. Many ages at once. Also...agree with each is different. I have 2 with IQs very, very close to one another, with different strengths and weaknesses and VERY different personalities. They each present their own unique challenges.

We, too, liked play-based for pre-K. It is great for social skills. Also, even if your DC is in school all day (and I agree that K usually includes lots of social-skill work), hopefully, there will not be enough homework for quite some time to prevent playdates after school...plenty of time to work on social skills.
