And another product for the lazy parents of our time (provided it's real).
40 years ago, parents had to use cloth diapers on their babies and spend a lot of time cleaning the baby and eventually the cloth diaper.
Then we 'progressed' to disposable diapers and baby wipes - untape, run two wipes down baby's crotch, use rash cream, tape the new one to the baby and just chuck the used on into the trashcan. Of course no one thought of where all they go - the local landfill. I'm sure if you dig deep enough, you may still find your own baby diapers!
And now we've taken the next step! You will no longer receive complaints from passers-by when you change your baby on a park bench, a bench at the mall, on a train seat or one of those changing stations in the bathroom. No, now you can just stick your hands into the kid's pants, fumble around and pull a liner from the front of the diaper like a magician pulls a cat out of a hat, and then present your baby's solidified piss to the world like a trophy. No more need to expose the baby's bits and pieces to the world - just stick a new liner in and you're done. Saves time too.
However, you don't want to be an early adopter of this technology - some people may get second thoughts when you randomly stick your hand into your young kid's pants and fumble around.
