My DS walked "early" at 10 months, but he didnt speak until 26 months. My IQ was tested as a child at 139, and my son is a lot like me. He has some "quirks" though so we thought probably low 140's. We did an short IQ test through the school and he scored >160. I was nervous when we did the assesment testing and the WISC IV that maybe the first test was just a fluke, but his GAI on the WISC IV was at 159. He is also my oldest so I really had nothing to compare him too. I just figured he liked to learn like some little kids liked to play games, lol.
