We keep stumbling on products we wish had been out, say, 2 or 3 years ago. But that doesn't mean we can't pass these items on to new parents. Take a look at the Combi iPod Bouncer:
It takes the everyday bouncer we used to use to a whole new level. It comes with a wooden toy bar, hammock style seat and a collapsible canopy. But the best part is that it has a built-in sound and vibration unit that plugs right into your iPod. That means your little munchkin can rock and bounce along to your customized music.
