Use it all the time!
This has been so handy with my newborn. I use the white noise for naps and bedtime, and the rattler is a good distraction if were out somewhere and hes fussy. I like that theres a timer and music option too. Only wish that the heartbeat noise could be played at the same time as one of the other white noises.
