Not very reliable results with my sample = 2, but....
DS8 (DYS) was INCREDIBLY active in utero. He's still INCREDIBLY active, so I agree with PP that you should rest up now.
DS6 (not tested) was less active in utero, and is less active than his brother. I'm not sure where he'll end up on the GT spectrum. I'm fairly certain he's at least MG, but he can surprise me sometimes with his insight. He doesn't have the same drive to learn that his brother did since birth, so his level is less obvious.
Congrats! and best wishes. What does Mr. W think of the impending arrival of DD? Older DS nick-named younger DS when I was expecting. It was really sweet.
