It is a general object of the invention to provide a highly reliable moisture indicator for diapers, surgical dressings and the like which is capable of being manufactured cheaply and can be treated as a single-use, throw-away item.
A helpful tip would be to use disposable diapers with a wetness indicator. Pampers is one brand that has the clever color-changing wetness indicator. No need to stick your finger in the diaper or sniff it to get a sense of whether it has been wet or not. If you do not have a wetness indicator diaper, another tip would be to place a piece of tissue paper in your baby's diaper to help better reveal the secret if she wet her diaper or not.
