If it wasn't for this video, I'd still be holding an inconsoleable Brooklyn... Poor baby, I have no idea what was wrong with her. I changed her, fed her, swaddled her, rocked her, sang to her, etc. I did everything I could think of and nothing was working so I looked up some "sounds of the womb" videos and ended up clicking on this when the first one ended. It worked like a charm, she's passed out in the bouncer now.
