Breakaway4 - my two are 3 years younger than your two and 2 years apart from each other, yet I notice a very similar pattern with them already. If I get DS5 tested, I will get DD3 tested when she's a bit older as well. I'm not sure what my brother's IQ is, and I'm not sure what mine is exactly. But I know I was tested several times when I was younger. I don't know if he was.
