When you first plug your crib in, you should see a slow-blinking white LED on top of the monitor arc. Once the crib is ready, the LED slowly blinks in a light blue color.
If the light on your monitor arc is blinking green instead of blue, please try rebooting your crib by unplugging it, waiting for the light to die out completely, and then plugging it back in.
If you have already tried rebooting and it still isn't blinking blue, head to:
Settings > Crib > Wifi > Reconfigure.
Once the light begins to blink blue, continue pairing your crib with the Cradlewise app.
