I have to have white noise. It does not matter what, as long as it is something. It drives me crazy to be in a silent room. (although, I have other mental health issues that relate to silence, so that is just me). My daughter is 3 and has been used to sleeping with a fan on since she was born, she relaxes and goes to sleep in a place other than her room when some form of white noise is used, but if not eventually she will fall asleep. It is just more frustrating for us, and since I need something anyway, it is better for me that she likes the white noise. I don't think there is anything wrong with it.
