Babies love to jump - once they discover their legs. This jumper has been a huge hit with my daughter. She loves all of the different toys on it, and she is able to swivel around all by herself now. So when she gets bored with one, she can swivel to the next. We have even attached some of our own toys to it as well, with the extra loops on the top bars. The seat is nice and large to accommodate any size baby. We just used a blanket when our daughter was little and needed more support.
