Elmo Learns about Experimentation

Never had a problem myself with my daughter, and we used cloth diapers.

Some babies skin are very sensitive to adhesives so I think it would be better not placed on the child's skin. The baby might peel it off, too and chew on it. Where on the skin would this be placed? In the area that will get wet or maybe - ew - even poopy? Because we all know baby poo travels... Would it be washable? I hope so! Why not just make an outside pocket for the device that could sense warmth from the urine?

Ah, my wife and relied on the natural "sensors" of odor.

If you don't know when your baby needs to be changed, you aren't paying enough attention to your baby.

I can see how such an aid would be useful for a daycare center, though.
