Really, I'm just surprised it took this long.
These days, kids get potty trained later and later, because if you're using disposables (or perhaps cloth with a service), it's manageably easy to deal with dirty diapers well past toddlerhood and into young-kid-hood. If you're doing the laundry yourself or don't have the latest in leak-trapping-technology, you're going to be a lot more motivated to get your kid trained to use the toilet. So therefore the parents are less motivated to get potty training over with. Additionally, disposable diapers do such a good job of “wicking away moisture” that the kid may not even know he's wet. And the best way to motivate a kid to not wet himself is to make the sensation of wet or otherwise soiled be an obvious and uncomfortable one.
So now, Pampers has created a new product for a problem we didn't even know we had: diapers with Wet Sensation Liners.
New Pampers Feel 'n Learn Advanced Trainers™ are the only training pant with the Wet Sensation Liner™, which allows a child to FEEL when they're wet to help them LEARN when it's time to use the potty.
The Wet Sensation Liner is a soft, suspended liner designed to be in direct contact with the children's skin, so they can feel a sensation of being wet, like with underwear, but with leakage protection. While the vast majority of wetness is absorbed, this suspended liner actually holds a small amount of wetness against children's skin for a short period of time, helping them to associate these sensations with having to go potty.
I'm afraid I'm a bit of a tease, however - they aren't available until August! Of course, I make fun of them now... I'm sure that a year from now I'll be buying up stock.
On a side note, I love how they have to bold and capitalize FEEL and LEARN so that you understand that they are FEEL 'n LEARN diapers. Oh, I get it! It's because they're LEAFing and FERNing! Er, wait.
