Benji stays awake all night, providing soothing sound while Sydney snoozes and helps lull her back to sleep if she stirs throughout the night. When we switch Benji off 12 hours later, we are usually staring down into a smiley, giggly baby, which is the true reward of the highly coveted good night’s sleep. We’ve gone as long as three consecutive nights between charges, but rarely do we neglect to recharge it every 1-2 sleeps.
