I threw my book away but is there a way to make the music stay on longer? Hannah keeps waking up when it turns off crying so were having to do it about 3x!!:/

 

We have them and I am not sure where our directions are...but there are settings in the back where you can do music and white noise, the music stays on for about 30 minutes or so and then the rest of the night is white noise. I'm not sure if you can make the music stay on longer.
