I tried to find one but the closest one I had near me lives and hour away and the amount she was charging was outrageous. I would do it if I could since I had a traumatic first birth I think it be good to have it to even the hormones out.
The doula I had does that. I think it can be really great. Personally I didn't do it. If I was able to have my birth at my midwifes birth center I was going to take mine and plant it under a new tree. But I ended up having to go to the hospital and they don't let you take it home.
