R.D.
I've done all my studies but have yet to take the certification class... so I'm literally thissuperclose to becoming a post partum doula :)
Visit DONA dot com for excellent starter information, class schedules, and more!!
I have not used a doula, in fact, I used pain meds during child birth because I'm a chicken, and by the time I knew what a PP doula was, I didn't need one ;) Just because I used meds doesn't mean I don't support natural childbirth!
The only downside is most of the time, YOU have to be the one to really promote yourself.
The upside is, having had kids, you already pretty much know what to expect outside of the textbooks ;)
I want to be a birth doula once my kids are old enough for me to split at a moment's notice... for now, I want to finish my certification and help families establish their new roles as mom, dad, newborn, big siblings, etc.
I posted a question on this FOREVER ago and got GREAT feedback; if you have the time, check it out, good luck, and PM me if you need more info!
