This toy sleeps in the room where the kids are playing. Everybody has to whisper or talk softly. The threshold and the sleeping plan are set remotely by phone. Only the parents have access to the settings. If you wake the baby up it starts crying of course.
During the waking hours, acceptable amounts
of noise cause the baby to smile happily and to start cooing.
Instead of a crying baby, this doll can be replaced with a puppy that yelps or a large dog that growls at first and then barks wildly.
