This swing was a life saver! Many reviews said that it wouldn't swing, we had no problems as long as you gave it a little push when you started it. My son would sit and swing in this for extended periods of time while napping. For a while this is the only place he would nap. We started using it when he was about a week old and used it daily until he was about 6 months old and still frequently until he was about 8 months old. We had no problems with the motor, but like I said we would always give it a little push when we started it.
