My oldest my son was crawling on his 1/2 birthday exactly 6 months and walking at 8 1/2 months and singing the ABC's, talking in full sentences, and understanding some simple spanish words (I swear) by the age of 2, Doctors always took a double take at his chart because he was and still is such a motor mouth. Then my daughter came along and she is the opposite she was 7 months old when she crawled, 10 months old before she could walk, and now she is shy of 18 months and starting to put 2 and 3 words together. She tries to keep up with big brother but other than that he does things for her and speaks for her so she just sits back for the ride, must be nice. So with my youngest it is the opposite. :)
