How funny that our son's first word was "No" at 8 months. It hasn't stopped since, lol! He walked at 11 months but then almost immediately ran. He was talking in full sentences just over a year. The really striking thing for us was his use of language and his memory. He remembers EVERYTHING you say and will pull it out years later. Never tell this child "When you are 8, we are going to ...." because he will call you on it. He also heard a vocab word, would ask us what it meant, and then weeks later use it correctly in a sentence. He is a sponge period. He was lining up cars methodically by 8 months and had excellent hand/eye coordination and fine motor grasp.
