I have no idea why, but I had a desperate wish to be hair free for birth, so I got a XXX wax (leaving the landing strip) the week before I was due. I'm glad I did, it felt nice in the water I think I might do it again for the next one, cos I'd plan another waterbirth. It's not a public consumption thing, just a water thing - I love water and how I feel in water and the less friction there is, the more watery I feel!
