Have no idea if this will work or not but saw it somewhere (another thread???) for getting baby to move from under ribs - wait for it ...... frozen peas (or any frozen veggie pack). The idea was to place the frozen item in the area where the baby was digging into and the baby would move from that area because it wouldn't like the cold !!!!!

Like it said no idea if it will work if the baby is in pelvis area as this might mean that it is partially engaged. But might be worth the try ????
