Angry Mom mornings

As the title says I'm an angry Mom in the mornings before school drop off.

I yelled so much this morning and the worst part is, my kids are 2 & 4. Toddlers!!! How ridiculous is that.

How can I make mornings a little smoother and positive. Any tips or tricks?

Right now they both pick out their clothes the night before and I give them two breakfast options to choose from.

Anything else to make me less overwhelmed, this angry, thus irrationally yell and my kids and then feel like shit about it the minute we're all in the car.
