摘要： The present invention is a reusable wetness indicating cloth diaper which uses a thermally sensitive indicator to indicate that the diaper has become soiled. The diaper of the present invention includes material which at least partially thermally insulates the outer surface from said inner surface and an indicator on the outer surface which provides a visual indication when the outer surface has a temperature above a given threshold. The temperature threshold is chosen such that the visual indication will generally not be present when a baby wearing said diaper is dry, but will generally be present when the baby secretes waste material into the diaper. A thermochromic ink indicates a temperature change in the diaper. A plurality of discrete indicators are distributed over substantially the entire outer surface of the diaper with the indicators forming a repeating pattern. Desirably, the indicators cover a significant portion of the outer shell of the diaper so that the wetness condition can be easily detected from most viewing angles of the diaper in an aesthetically pleasing manner.
