Nanit the AI nanny tries to unravel the mysteries of a restless baby

When my wife and I became parents, the most important weapon in our childcare arsenal was an A5-size notebook. In this mighty tome we wrote out every single data point relating to our new baby, from the quantity of milk she drank and duration of sleep through to the volume of excreta. It was, after all, only with this information that we were able, in our sleep-deprived and confused state, to coordinate how to meet her needs. Devices like Nanit's artificially intelligent baby monitor are designed to outsource much of that brainwork. It's a $349 night-vision camera that hangs over a cot, using computer vision and deep learning to monitor your little one's sleep. The little gadget is relatively small, but it packs a microphone, speaker, camera, nightlight and temperature sensor inside its body.
