A cup holder assembly for a stroller has a slider that is carried on and slidable along a part of the stroller frame between a stowed position and a deployed position. Retention members, such as retaining rings with counterbores, are positioned over the snap rings and prevent the snap rings from expanding outwardly and being released from the grooves. A second element is designed as a lever. The retention portion includes an interior space that is in communication with the lumen within the elongated portion and has at least one opening for urine drainage.
