LOL - yep... my DH had a go. The minute the midwife turned her back, he grabbed it off me and had a good suck. He said it made his chest feel all light and floaty. I just laughed. At the time, I was waiting for the epidural to kick in so I wasn't really needing it as much as I had previously.
I think he was more disappointed than me when they packed it away once I could no longer feel my contractions!
