Got Sleep?

When I was single, I would end the long work week by going out with friends on a Friday or Saturday night to a club... and I would drink..maybe try to shake my booty in a way that looked somewhat visibly appealing from all angles .. and I would get home late.   It didn't matter what time I went to bed - because I KNEW I could get my 7-8 hours of sleep that night...   so, if I went to bed at 2am.. I could "sleep in" until 9-10am and still go out and enjoy the day..feeling rested. 

Why doesn't this same theory apply to kids?  

The boys sleep schedule has been off the last couple days because they have been home sick, and they have been napping more than usual.. causing them to stay up a bit later at night..  But yesterday, they were up at 6am.. their regular "I'm up" time... they didnt nap, AND they were STILL able to stay awake past their 8pm bedtime.. up until 9:30pm.. with an overflow of energy to boot!  all day!!  phewy - OK, they are down..  its 9:30.. Beaver Boy and I decided to watch a movie.. and then some SNL..  anticipating a morning to "sleep in" until maybe 7:30.. since they went to bed so late after a full day of endless motion.... 

Nope.  6:00 am.... at my bedside... looking like he has been up for 2 hours.. no puffy eyes or morning breath..   "mom.  get up .  I am up.. can you get up now?"
