My morning routine has always been to get up and use the bathroom, brush my teeth and then go about the rest of my day. If I eat breakfast at all, it's likely to be either after I've already left the house or the last thing I do before I leave. I've read somewhere (not sure how true it actually is) that you're not supposed to brush for half an hour after eating, so there's basically no point in time where I could brush after eating breakfast.
