I, Robot Cradle

You knew it was coming. A robot that could rock your baby to sleep in his crib. And this isn't a Will Smith movie. The Lullabub has four modules that are placed under each leg of your child's crib. Each module produces a soft rocking motion—like the suspension of a car—with four settings and an automatic timer to shut it off after the child drifts off. Look for it sometime before the end of the year.
