Off my face! I told my very proper mother about how her grandchild was conceived. She did not appreciate the information about her daughters sex life. They also took it off me as it stuffed up my breathing and pushing (ended up with a tear as I pushed out of sync with one of my contractions) and I begged like a druggie to get it back (and I didn't get it back). I also didn't realise that I had delivered my daughter even though I had just caught her and she was in my arms.
Truthfully, it made no difference to the sensation of the contractions. It might have helped with the stitches but by then I was meeting my baby and I didn't care what happened!
I have no idea how I ended up with it in my hand - I think the midwife put it in my hand as I started pushing (I was very suggestible). I didn't want it as we had done a calmbirth class and had been warned about how it interfered with breathing. But it all worked out in the end!
