Query: Sleep through the night!

This swing was a life saver on difficult nights. I would swadle my daughter, turn on some static noise, place her in her swing, and all was well. A swing is essential during the first three months. At three weeks old she slept six hours in it and by four she was sleeping eight with an effortless transition to her crib.The songs are somewhat cool too and not annoying.
