Our LO has been fussy the last 2 nights, and tonight she started being fussier than ever. After about 10 minutes of shhh-ing, clean diaper, swaddling, rocking, nothing seemed to work. However, DH, brilliant man!, remembered reading about using a vacuum as white noise. It totally worked!

Our vacuum is really loud though, and I don't think that our neighbors would appreciate us using it in the middle of the night (apartment), but google to the rescue!

Youtube has a video that is 12 hours of vacuum noises! I think I'm in love, first with DH for remembering, second with youtube!
