I believe my son could stay awake all night if we would let him. We'll be out at somebody's house, drive home at like 10:30 pm, get home, and my son will still be awake and want to play for "just a few minutes".
Tonight, I put him to bed at 9:30 pm. Finally at 10:45 pm he had calmed down enough to wear he was just laying there in bed, playing with his book, while he waited to go to sleep.
I don't know how he does it. Most kids are out like rocks on bedtime car rides, but he's able to stay awake. God has uniquely gifted him.
He does get an awesome amount of sleep, though. He'll sleep 10.5 hours at night and takes a 1.5 hour nap. So that's 13 hours. Pretty good. JM
