If you sit down to feed the baby, your toddler will start throwing herself bodily against the refrigerator to alert you to the fact that she's hungry.
So, for fear of injury, you'll put the baby down and get the toddler some yogurt. (This interruption will cause your baby to scream.)
After you sit back down to finish feeding the baby, your toddler will eat approximately 10% of the yogurt, and apply the remaining 90% to her body and hair.
As you take the toddler to the sink to rinse her off, the running water will remind you that you've had to go to the bathroom for the last hour.

As you're scrubbing the toilet, your oldest child will materialize and inform you that she has to go to the bathroom RIGHT NOW and needs to use the toilet you are presently cleaning and she is NOT going upstairs because it's an emergency. You leave her to it and try (unsuccessfully) to get your toddler to put her shirt back on.
She'll climb up onto the toilet, but will perch on the very edge even though she's been fully potty trained for over a year and knows not to do this and knows that it will make you very angry when she pees all over the ground.
