hello doc, I wanna ask that is it safe to use white noise whole night and while every nap, as my baby who is now 5 months old, wakes up with even a drop of a pen. and he sleeps around 6 in evening when I play white noise on TV and stops at next day around 11 am. As I a working woman I work whole night at hoke in the same room my baby sleeps, so while playing noise his sleep doesn't gets interrupted. May I know how much dB should be the noise.
