When toddlers get tired...

I'm not sure why it took me so long to realize, or why, once realized, I find it so hard to remember, that when toddlers get tired they don't simply rub their eyes and curl up like kittens to go to sleep...at least not mine.  Their little bodies get revved up and falsely portray an overabundance of energy.  Or, in the case of my two-and-a-half year old son, he turns into a crazed Jack-in-the-box, but wound up and released from his tin 4x4(x4) box.  I have to remind myself: he's TIRED, when he starts running laps around the house like someone strapped a stick of dynamite to his butt.  He's TIRED, when he starts throwing the newly folded laundry into the air and laughing maniacally at his own antics.  He's TIRED, when he starts poking his baby sister in the face and jumping just out of reach every time I try to stop him.  He's TIRED, when he throws himself on the playground floor when it's time to leave instead of walking angelically over to the car...or stroller.  He's TIRED, when he flails his arms in a "you-can't-catch-me" kind of way as I try to put on his coat to leave a friend's house.  He's TIRED, when he starts spitting his lunch at the ceiling.  He's TIRED, when the minor bump against the table sends him wailing on the floor.  He's TIRED, when he arches his back and refuses to sit in his carseat after a run of errands.  He's TIRED, when he starts kicking and screaming during a routine diaper change.  He's TIRED, when he cries from his bed for a snack...or milk...or water...or chicken and rice at 9 o'clock at night after eating three solidly round meals.  He's tired...and as long as I remember that, I can keep myself from thinking my child has suddenly and surprisingly turned into a demon.
