I think you can take as many as you want, but it gets expensive! ? I am taking all of the classes that St Joe's in Burbank offers (where I will be giving birth) and then I am going to buy the hypnobabies course and study from home.
I also looked into the Bradley Method, but decided against it. ?There are classes in the area and it takes 12 weeks.?
UCLA in Santa Monicawhere I hope to deliver, offers basic chilbirth classes that are 8 hours, Bradley - 12 weeks, and Lamaze, and maybe hypnobirthing too, I just requested info on them and I think we are going Bradley. We'll see.
I also considered Golden Bridge chilbirth classes, they come highly recommended and I love my yoga class there.
I may be biased, lol, but I believe Lamaze classes are the best classes if you are planning a hospital birth. Hypnobirthing is a great additional resource, but I wouldn't eliminate Lamaze class altogether. They are complimentary and you will receive information in Lamaze classes that you probably won't get in an Hypnobirthing class.
I used both techniques with my last two babies and I really feel they work well together. I am not hypnobirthing trained, but in my classes, I do teach a lot of the same techniques that hypnobirthing teaches as I feel they work well! (at least they did for me!)
