You could wake up in the middle of the night for a short period of your life and tend to the spawn you insisted upon this world. Or, you could just buy an automated cradle.
By Suima, this automated cradle is just two teets short of raising your child to age two for you. It tracks your baby's state through an integrated microphone, and should tears arise, it will rock your baby back to sleep, slowing the pace gradually to eventually match the rate of a mother's heartbeat. We know, it's a hell of a sales pitch.
