A toilet training device has a target sensor for sensing an impact of urine, a first suction cup for securing the target sensor to a toilet, a music box for providing a feedback, and an insulated electric wire for connecting the target sensor with the music box. The target sensor can be positioned unobtrusively within the toilet. When a user urinates, the target sensor detects an impact of the urine when hit, and the target sensor triggers music in the music box through the insulated electric wire.
