It’s 10:50 am when my Apple Watch dings. I lurch unsteadily to my feet. I spent the early part of the morning in a whirlwind, dressing, feeding, and packing my 2- and 4-year-olds off to day care and preschool. Then I returned home, plopped down at my desk, and started my workday. Since 8 am, I’ve barely moved.
