Adults help children to manage transition—by giving them bedtime routines, cleanup reminders, and warnings of “Five more minutes!”—but we adults often expect ourselves to careen effortlessly from one activity to the next.

Running activities too closely together makes me feel harried and irritable, and habits of transition help me to switch gears more calmly.
