Let me know what works for you, because mornings are not the best event at my house and both DH & I get the kids ready and drop them off!
I lay out their clothes the night before. I get their lunch ready- if they are taking one that day-the night before.
I get up first and get their breakfast ready before showering. DH then gets showered and dressed- I dress while he is showering and then we wake up the kids. We help them dress, then DH brushes teeth and I do hair.
Leaving as few things to do in the morning helps. For us, rare is the morning that one of the kids doesn't wake up cranky,usually its DS ( he is cranky on the weekends too- when he can get up whenever he wants!) but DD is happy to fill the void if DS wakes up okay.
You do have to be a drill sargeant because they get distracted by everything. I often tell DS that we have to go quickly so mom and dad won't get into trouble for being late- it works- withhim DD doesn't care, butluckily she's moslty ok!
I find winter is harder because the kids have to put on coats, ahts & gloves too. If you are driving them, I recommend just putting hats,gloves and scarves in the backpacks so they have them at school.
Also, my kids's daycare is very family friendly and that makes it hard to get out of there quickly. My kids always want us to stay for a few minutes because somebody else's parents are usually hanging around. A lot of the dads just take the kid to the door of their breakfast room, say hi to the teacher and get out quickly before the kid can protest!
Good luck!
