A portion of the elongated stem adjacent to the cup portion is provided with additional flexibility to allow bending of the elongated stem at the point of flexibility thereby permitting the cup to be folded into a position substantially parallel to the elongated stem thereby facilitating insertion into the birth canal. In a preferred embodiment, a separate handle piece is attachable to an end of the elongated stem opposite to the cup portion.
