A device for assisting in the active and pushing stages of childbirth. The childbirthing device consist of a first loop that can be used to provide resistance for pulling. The first loop is then connected by means of a length of rope to a braided handhold two wrist loops attached thereto. A pregnant person can then insert her hands through the wrist loops and grasp the braided handhold. She can then pull against tension that is applied to the other end of the rope. The pulling action while pushing redirects where the pushing takes place in the pregnant persons body and increases the effectiveness of her “pushing”. This decreases the time necessary for the fetus to descend through the birth canal. The wrist loops provide support to the person who might be holding the first loop, on the opposite end of the rope. In case the pregnant person suddenly releases the braided gripping knot the support person won't descend to the ground or fall backwards.
