Query: love the jump-up!

We bought this for our 5-month-old son a few weeks ago and started using it right away. He loves it! We don't leave him in it too long, just about 15-20 minutes at a time, but he bounces the house down and loves chewing on the little toys. It's a great way to keep him occupied for a short time before he can sit up and play on his own. Highly recommended!
