The Gaskin Maneuvre is supposed to be effective in almost all cases - you turn onto your hands and knees and rock your hips. That's it, it usually frees the stuck shoulder because it open the pelvis more. Anything that gets your body weight off your sacrum makes a huge difference as it's like a little hinge and can move a good bit out of the way if you're not lying on it. Crawling around on the floor works too. THese are difficult things to contemplate when baby's head is out already but so much better if they allow you to avoid the trauma to you both of forceps.

The vast amjority of women who have forceps do not need them for their next baby, unless polio or rickets has actually physically deformed their pelvis to make it too narrow.
