As a doula - child birth educator I've had many dad's confide in me that they can feel a little nervous about labor because they are not 100% sure if they will be able to help their partner through labor. Basically they are looking for real tips that they can use. That's why I made this list for you, to help you, help your wife through labor.
This is one of my favorite videos of all time! Conception to Birth -- Visualized by Alexander Tsiaras. Every time I watch it I am blown away how incredible the human body is and how amazing pregnancy is. The first time I learned about Alexander Tsiaras's work I was sitting in the office of my friend's OB/GYN and he had the book Conception to Birth - Visualized sitting on his desk. I picked up the book and freaked, (in a good way) it was one of the most amazing things I had ever seen.
