I found this app with my second baby and just remembered and started using it again with baby girl 3. If you ladies are wanting to try it.. it's a godsend! I mix the two white noise sounds and she can be fussing and it knocks her right out! Love using it during night time feedings.

You can mix all kinds of sounds at varying volumes. I used it for a long time with my second. Started with white noise as a newborn and such then by about 6months moved into rain and water sounds to help block out sounds since we room shared a long time. Heck.. it helped me sleep by then lol..
