Whatever you choose I'd highly recommend reading Ina Mays guide to childbirth. It helped shape our beliefs about birth being empowering and being informed and that my body is built for birth.
We did
Beer and bubs,
Doula,
Calmbirth,
Private LC class
ABA class
And lots of reading and research and it was worth every dollar for the amazing birth experience we had.
I think it's worth doing the hospital classes so you understand how the hospital operates etc. calmbirth is worth it too if your budget will cover it.
