A friend from church, who is a certified nurse midwife, sent this link on to her friends. It's a very comprehensive, nation-wide birth survey that's being compiled. I'd already completed it shortly after Hans was born, but I thought I'd pass it on to any of my readers that would like to fill it out. Eventually, it should provide a great database to learn about birth practices both general and specific to providers. You don't have to have had a natural birth or anything of the sort to fill it out; they want all kinds of births included. You just have to have given birth in the last 3 years. It does take a while to complete (20-30 minutes). I'd encourage you to check it out.
I was reading back through it after I got the link, and it really made me SO grateful again for the great prenatal, labor and delivery, and postnatal care I received! Seriously, I <3 my midwives! They have all the knowledge and skill a birth might require, but didn't feel like they had to use it on every birth ;-).
