Sleeping

How can this child need so little sleep these days? Honestly, no naps, fighting sleep until 9:30 - 10 p.m. and waking up at 7 a.m., sometimes 6 a.m. WTF is going on in that giant head of his? I did read that bedtime becomes a fear at this age, but I asked him why he doesn't want to go to sleep and he said he misses us and thinks we are doing fun stuff. DUDE, staring at the television brain-dead from chasing your crazy tail around all day is NOT FUN STUFF - GO TO BED!
