Query: HATED IT

We are extremely unhappy with this jumper. While my daughter is in the upper percentiles for heighth, we didn't feel that we could use it @ four OR five months because the seat is so deep. She continually hit her mouth on the tray. Also, it is very hard to adjut to the right heighth. I have seen other jumpers that work much better, and we will purchase one of those!
