I have the classroom (not homestudy) materials- workbooks and CDs.
I found it extremely useful for both of my labors; though due to circumstances didn't go fully unmedicated either time. (First time was a stillbirth, and the materials helped me stay calm, but I went with IV meds since the baby's health was not at risk; second time the materials allowed me to get through a good deal of labor while still at work, just pausing at waves of contractions between some data entry work. I went to the hospital at 6 cm and contractions 2 minutes apart- but I decided to get the epidural because her heart rate was being wonky and I wanted to make sure if I needed a c-section I wouldn't need general. Turns out I needed the emergency c-section, but the epidural wasn't strong enough and I needed general anyway.)
It isn't recommended by the company to use the classroom materials on their own; but I thought they were sufficient (I also didn't realize at the time they weren't the homestudy- the ebay listing I got them on was a bit misleading.)
I paid $125. Feel free to PM me with an offer if you'd like them. I'd prefer to ship to US address.
