My daughter had colic really bad and could never get to sleep easy. Noticing she loved the water, I looked for an app that would play rain noise or a stream. I turn on the rain and underwater sound together before she gets into the bath and let it play all night long on our iPhone dock. Its not only worked wonders for her, its ultimately relaxing for daddy and me. Money well spent! Love it.
