A diaper changing mat comprising an attached, flexible and infant-drapeable, fold-over urine shield structured and arranged to prevent urine exposure from infant-generated urine while still providing easy access to the infant's diaper area. The diaper changing mat is preferably disposable. A preferred heart-shaped urine shield blocks urine streams without hindering access to the infant's diaper area. Alternately preferably, the diaper changing mat may be reusable and washable or preferably comprise a removable waterproof insert. The diaper changing mat may also attach to a changing-table element, such as, for example, a foam pad.
