Our second baby didn't really like the Snoo (however, he's nearly a year and a half old, and he still doesn't sleep well), but for our first kid, we got the Snoo after going crazy from a month and a half of colicky baby screams. And—I'm not making it up—she slept through the night from nearly the first night. It wasn't consistent from there until she was older, but I'll never cease to praise the machine.
