I loved this bouncer when I first saw it. However, it pretty much fell apart. When my Daughter was 4 weeks old and laying in this, she would tilt the entire thing. When I laid her done in it, the thing would almost collaspe. The Vibration part didn't last long, I was changing batteries every few days! The bird chirping was so low, you could hardly hear it.After those first couple of weeks, we went out and bought a less expensive bouncer and she's still using it and she's 6 months old :)
