Just a few waterbirth videos I've come across recently.
This first one, linked from Bellies and Babies, takes place in St. Thomas Hospital in London.
The second one is a home waterbirth/Hypnobirth. Thanks to one of my commentors for posting the link--I hope you don't mind me re-posting it here!
The last video is a home waterbirth of twins that took place in Australia with Lisa Barrett, (whom I greatly admire). Lisa is a UK-trained midwife who now practices independently in Austraila. I couldn't embed the video directly onto this post, so you'll have to go to Lisa's site to see it.
