nutribullet baby is making a weird clicking noise and the motor stopped, is it broken?

Yeah, this one's common. The motor is designed to shut off if it overheats. Never let it run for more than one minute at a time. That can permanently damage the motor. Unplug it, let it cool for a few hours, and it should reset. Also, check that the Extractor Blade is screwed on securely before you place it on the base—a loose blade can cause issues.
