Query: Great Bouncer

I love this bouncer! I used to have one made by Fisher Price with massage and vibration that we loved, but this one is even better.One thing to point out... perhaps those people saying it does not bounce or you have to do it manually do not understand that bouncers only bounce when the infant kicks. If they are putting a newborn in it and expecting it to magically start moving, of course that is not going to happen. That is not a flaw in the item, that is just how bouncers work. This one bounces as much as any other bouncer we've tried out.
