My DS4 was very alert after birth...and has always needed less sleep than the average child. He barely napped as an infant but always slept good through the night. my dd1 is the same way with her sleeping (although she is completely different than him). He still requires less sleep then most. And when I wake him up in the morning....he always says something quite obscure and interesting even before his eyes are open. It's like he is always thinking. Several months ago before the light was even on he said "mom I did a math problem for you on the floor" I told him I think he was dreaming and he said no it was really on the floor and got up to show me how he had used foam numbers to say "6 + 3 = x" I was a confused until I saw him reaching for a I and he said "oh I messed up....I knocked the I that's supposed to go infront of the X....it's 9 in Roman numerals" wow, I definitely need my coffee before I think at all.
