I would always feel a little jealous when my girls were tiny, all snuggled up in their bouncer, napping through noise that would shake a building. "They should totally make those for adults!"...well they have:
The adult sized Bjorn Babysitter Balance. They actually just made one for a show so adults could see how comfortable they are. So, I had the thought. They should make giant, adult size versions of all baby apparatus', so we can see just how much our child will enjoy it. Imagine, the Adult Bumbo Seat, Adult Exersaucer, and the Adult Johnny Jump Up (steel reinforced door frame required). I'm thinkin' I would dig this!
