The New York Times examines the new generation of wearable devices designed to track a baby’s sleep and sleeping habits.

Mimo is just one of several devices that will focus on tracking infant sleep. Gadgets like the MonBaby, which is a button that you snap on to the front of a baby or toddler’s clothing during sleep, or the Sproutling, a data-tracking anklet, will also track sleep, breathing and motion. The Sproutling even promises to let you know if your baby is fussy upon waking.
