I found the video to be somewhat biased as well, though I think they did ultimately try to avoid that. It probably would have been more advantageous to have someone interviewed who was a little more knowledgable about water and natural birth like a midwife..... However, unfortunately a large percentage of the North American population do not take midwives seriously..... hmmmmmmmmmm
Canada has a similar attitude towards waterbirth. In many parts of the country it's entirely unheard of and throughout the rest of the country it tends to be frowned upon. My grandmother thought I had "strange" ways before being that I breastfed and cloth diapered and had a midwife.....
But now that she found out that I'm planning to have my baby in a swimming pool in the middle of my kitchen she thinks I'm completely NUTS! Maybe she's right but that has nothing to do with my intentions to have a waterbirth!
Anyways, the vast majority of hospitals will not permit water births and I have yet to meet a doctor (doctors care for the majority or pregnant women regardless of whether they are labeled as high risk or not) who will deliver in water.
Midwives here do attend waterbirths and they do support the practice but provinces in which midwives are able to practice are limited , the option of waterbirth is still more often then not restricted to women electing homebirth due to hospital policy and this has resulted in the overall practice of waterbirths being quite small. I've been to well over a hundred births and have only attended 5 water births.
