This gives new meaning to the phrase, "There's an app for that." Being a father, I am unsure if this technology really provides value to a parent. In my experience, it was routine to check my kids for full diapers and if you didn't, they'd let you know! One specific time I could see this being beneficial is if they had diaper rash or an existing skin irritation that was aggravated by additional wetness. In that scenario you'd obviously want to change the diaper quickly.
My question is, will this device work on any diaper? Even washable and reusable ones? If so, that makes it even more appealing - depending on price of course for both the device and the app. Either way, I applaud Huggies for being innovative. They are setting an example to any organization that builds and delivers products. Always think, anticipate, and utilize the technology available to you in an attempt to improve your business.
