         2 . The apparatus of  claim 1 , wherein the set of diagonal braces comprises a pair of opposing rear diagonal braces and a pair of opposing front diagonal braces. 
     
     
         3 . The apparatus of  claim 2 , wherein the stroller handle comprises a generally U-shaped member having a pair of elongate bars and a cross bar connecting the pair of elongate handle bars, and wherein free ends of the handle bars are securely attached to the rear diagonal braces. 
     
     
         4 . The apparatus of  claim 2 , further comprising a canopy secured to the handle bars above the handrail for shading the infant. 
     
     
         5 . The apparatus of  claim 4 , wherein said canopy comprises a set of elongate struts secured together to form a rectangular canopy frame, the set of elongate struts comprising a pair of side struts, each side strut having a downwardly depending strut extension attached to a respective handle bar. 
     
     
         6 . The apparatus of  claim 5 , wherein said set of elongate struts further comprises a cross strut extending between the handle bars adjacent a top portion of the stroller handle. 
     
     
         7 . The apparatus of  claim 6 , wherein a canopy cover is stretched between the elongate struts and the cross strut.
