My ds1 was totally different as a baby. He slept a ridiculous amount of time (we barely saw him awake the first 6 months!) and was very behind physically. I found his baby book the other day and at 8 mo he wasn't sitting unassisted or rolling over. He was however very happy looking at books and stacking bricks (went ape if they fell over though). He didn't crawl until nearly a year old and wasn't talking until he was 2.5. He could recognise all the letters and numbers before he was a year old (hard to say when he was reading words as he wasn't vocal but we were certainly aware that he recognised what quite a few words meant by 18 months). He is very gifted (and on the spectum).
 On the other hand my dd was physically precocious - very like your baby. She was insanely alert and aware and never slept. She is bright but I wouldn't say unusually so.

Kids all do things differently bless them! I think they just like to keep us guessing....
