Thanks so much for the response. As I've read through the various forums over the past few weeks, I've learned alot and am sure I'll continue using this as a resource as my DS and DD (I've learned) develop and unfold. The response also confirms our decision (yesterday) to meet with a pediatric neuropsychologist to sort through what is "normal asynchrony" and what might be other. So, thanks Mark, Grinity and unnamed family consultant. I really appreciate your words.
