Not good

I wanted to like this because it fills up nicely and doesn't take up space. We still use it because it's so that we have, but it's annoying. It slides all over the tub, especially if you want the water to reach at least the bottom of the seat so that the baby is sitting in the water. That also means we end up using a lot of water to fill the tub. When my baby was a newborn, he would slide to to bottom of the seat, even in the recline position, and now (4.5 months), he likes to kick from the bottom of the seat and arch his back, which can tilt the seat backwards if we don't have a hand on him.
