My oldest rolled over the day after he was born and looked up at us with a big goofy smile on his face. The doctor was standing in the room when he did it and was SHOCKED and said it must have been an accident. He started laughing at me when he was 2 weeks old. He could stand at 3 months. He hit every physical milestone, including toilet training, way WAY before any child I've ever head of. He is now an NCAA Div 1 athlete. We knew pretty much from birth he was different as did all the mommies in my baby group. My younger child, is a completely different kid. He had delayed milestones. He spoke early (sentences at 9 months) but didn't walk until he was almost 2. They both have PG IQ's but little DS is the higher of the two. He is 9 and can't tie shoe laces or ride a bike both things that older DS could do at 2.5. They both have a rather odd take on the world. Older DS's girlfriend is always trying to figure him out but I don't think she ever will wink
