<unk>  with oilThe Oxford Radcliffe NHS Trust Document "Antenatal<unk> " 2011 describes the use of the pregnant mother's thumbs being placed just inside the birth canal, whilst she stands with one foot supported on the toilet. She pulls backwards towards her spine, whilst relaxing her pelvic floor, progressively increasing the pressure under her finger tips until this starts to feel uncomfortable. On the next occasion she uses both thumbs pulling backwards and then sideways, thumbs away from each other, to enlarge the 2 cm diameter opening of the birth canal progressively over time to 10 cm. by progressing to use the four fingers of both hands pulling away from each other, painlessly- to avoid causing tearing. It is not possible to stretch this opening further, because this will be limited by the distance between the bony walls of the pelvis.
