Can you explain this to me?

For the past month or so, we've been trying to get into a routine. During the last 2 weeks of our winter break, I mandated that we all (C, S, and me) be up, out of bed, dressed, fed, and ready to go--even if we were hanging out at home that day--by 9:00. Every morning that both C & I were home, we failed miserably. I repeatedly found myself still in my pajamas at 10:30 or later. With 2 adults home, we couldn't manage to get S ready for the day let alone ourselves. Last week, C's semester started; he is gone 2 days a week from 6:30 until 3:00 or so and one afternoon from 1:00 until around 7:00. Every day he has left the house at 6:30, I have managed to fulfill the mission I gave both of us: S & I are up, fed, dressed, and ready for the day by 9:00. I told C this and he looked at me as though I were Superwoman. He asked if S & I hung out in bed like the three of us do on the mornings that C is home. I told him we did all the normal things--we did S's "baby exercises" in bed, he nursed for 30 minutes after that (I manage to make myself a quick breakfast before he nurses, so I can eat while he nurses), and then he played in his bouncy seat while I took a short shower and got dressed. This morning, I've even managed to make the bed, wash a load of clothes, and run the vacuum cleaner upstairs--all before my online office hours begin at 10:30. Granted, C did feed the cats, make coffee, and unload the dishwasher before he left this morning. But why is it that I can get all of that done on my own while caring for S, but the two of us can't?

My explanation: I'm much more productive when I know I don't have anyone else to rely on. I don't spend half of my morning asking C for help or waiting for C to do something for me. I just do it myself. So why don't I just do it all myself when he's home? I've been asking myself that, and I have two explanations that I am happy with.

1. He needs to feel needed.
2. I don't want to do it all myself! I want us to work out a morning routine together that gets us all up and ready for the day by 9:00! I think we'll have to keep working on that one . . .
