Yes I used one with my DD. I think it helped. My little girl was in a posterior position so it was pretty horrendous pain but seemed more manageable than with my DS who was aslo posterior. The labour was shorter (only 6 hours) and I coped with air and gas only until the end and had to have an epidural for a forceps delivery. I would recommend it, I think it helped me focus and also helped me acheive my VBAC.
