Apparently the opposite of laying down is "laying up". As in, "Mommy, lay up! I want to go downstairs and have some cereal!"
This is particularly challenging at 5 or earlier in the morning, which is the hour that the boys insist on waking up. We even have experimented (granted, only for two days, and yesterday was not very successful) with eliminating the afternoon nap in the hopes it would exhaust them enough to end the bedtime battle and the early wake up time, but no such luck. It would seem that we have been cursed with early risers.
Of course, when they're in school, we won't be able to budge them.
