I have one early riser and one night owl. Here's what we've done to streamline the morning (and help on the days my night owl dh runs the show).
basket of clothes picked out the night before. Literally clothes in the basket. shirt, pants, socks, hair accessories, etc.
In the morning, I wake up, turn on the hall light and open their door. (brush my teeth, check my email, la la la). (that gives my slow riser time to slowly wake up)
I go in, put my hand on dd1's back and tell her five minutes, let my other kid sleep if she's still asleep or greet her if me walking in there wakes her.
Five minutes later (or after I get the coffee going and the dishwasher emptied), I go in and tell both girls time to get up.
They get dressed, go to the bathroom and have a goal of not returning to their room before leaving for school.
Come down, have breakfast. I offer one choice (which kind of cereal do you want), unless they are downstairs early. We brush hair in the dining room and brush teeth in the kitchen (we only have bathrooms in the basement and 2nd floor). Backpacks are kept in a backpack box, right next to school shoe spot. I am responsible for putting lunches into backpacks, but they do everything else.
If all that is done and you have extra time, you may read with your shoes, coat and backpack on.
Few other thoughts:
* How would an alarm clock be received? Not as the be-all, end-all to getting out of bed but rather as a put the task of waking on some(thing) other than dh?
* Allow more time for waking might be helpful. I'm a set the alarm and never snooze more than one time kinda girl. Dh sets his alarm with 15 minutes of snoozing built in. Otherwise the first 15 minutes on his feet are just like snoozing in bed (hand soap on his toothbrush, socks on inside out, etc.).
* Family discussion got us where we are right now. Erin suggested the basket for clothes -- if one girl wakes early and wants to they can carry their basket elsewhere to get dressed (leah's suggestion). Erin prefers to get dressed in teh dark and then face the world.
* Second grade was really hard for us in terms of balancing getting up and being ready to face the day. Third grade is smoother (knock on wood). I don't know what's different? We are making a hard effort for exercise after school and quiet reading time from 7-8, 8 being lights out.
