I purchased this for our new granddaughter opting over a conventional bouncer. I have to say best purchase ever ! Our granddaughter loves it ! Soothes with the little lullabies and the gentle rocking and vibration motions she is 5 weeks old and totally suitable. The frame is sturdy i am sure we will use a lot of batteries but definitely worth it ! All she does is sleep in it and appears to go into a deep comforting sleep.
