So you've just got the damn pack on your back and suddenly you need to pee.
Step 1: Wedge yourself and your baby into a toilet cubicle, taking care to lock the door behind you. No one needs to see you do this.
Step 2: Attempt to sit on the throne in the normal fashion. You can't can you? Because the baby-filled backpack is jammed up against the wall behind you, and your tush is not sitting where it should be.
Step 3: Think for a minute. Employ your once amazing problem solving skills (they were amazing until you went for about 256 nights without decent sleep).
Step 4: Turn around and sit on the throne backwards. Straddle it, in other words. Hey, it actually makes no difference. Though in case you're wondering, there are actually wrong ways to use a toilet:

Step 6: Give a smug smile to the people giving you strange looks as you come out of the bathroom. Bet they couldn't work it out!
