They wake you up at 2:00 a.m. with urgent potty needs. "How old are you? Aren't we done with this stage?" you ask in exasperation.
They suddenly need to throw up at 2:36 a.m.. So they do. "What's up with this?" you demand sharply as you jump out of bed, before you realize you have a Charlie Horse to beat all Charlie Horses, and jump around yelling "Ow! Ow! Ow!"
Sometimes they just need to stretch their legs, spin in circles, and dig a little nest in the blankets at 2:48 a.m. to calm themselves down. "Fine," you grunt, as you give up and get out of bed. "I'm up. What's your plan?"
They find each other, curl up into dog balls and fall asleep. It's 3:00 a.m., after all, and they're exhausted.
