I am panicking. The other night when DD, who is only seven weeks, needed settling I used my iPhone and found an app which plays the noise of water running. The old white noise theory. She quickly went from a tired temper to soothed asleep. In fact I fell asleep and for ten or 15 mins the phone would have been on near her head before I snapped out of it and pulled it away. are these apps safe to use? I now dont like the idea of mobile phones being close to her little head. Has anyone heard about these apps? And have any thoughts?
