Why Cry is a new device that lets you know why your baby is crying. This is only 1 step away from an invention you may recognize from Homer Simpson's brother...
From the WhyCry Website:
The WhyCry® monitor is a baby cry analyser. The monitor listens to the baby's crying for 20 seconds then digitally analyses it before indicating why.
The device then illuminates one of five crying 'expressions' telling you whether the child is hungry, bored, tired, stressed or annoyed.
The WhyCry® analyser comes with a comprehensive user guide and a symptoms chart so that once the cry has been translated the chart can then give pointers as to how to rectify the situation.
