Abstract: A convertible stroller assembly includes a stroller that has a seat and a backrest that is pivotally coupled to the seat. The backrest is positionable in an upright position for having an infant seated thereon. Moreover, the backrest is positionable in a reclined position having each of the seat and the backrest forming a diaper changing table. Thus, the infant can be laid on the infant table for changing a diaper. A pair of legs is each pivotally coupled to the backrest. Each of the legs is positionable in a deployed position for supporting the backrest when the backrest is positioned in the reclined position. A pair of privacy panels is each slidably coupled to the seat and each of the privacy panels is positionable in a deployed position to conceal the infant while the diaper is being changed.
