Abstract: A crib assembly includes a rocking assembly which rocks the crib mattress either up and down in a vertical plane or side to side in a horizontal plane. The rocking assembly can be either manually activated or automatically activated if the child cries out. The rocking assembly will shut off after a preset time interval, but can be reactivated if the child is still crying at the end of that preset interval. However, if the rocking assembly is reactivated, an alarm circuit is activated by the second activation of the rocking assembly, and this alarm circuit will alert an adult that one rocking cycle was unsuccessful in helping the child to return to sleep.
