Asking on behalf of my friend, do you think prenatal class organised by hospital is useful? Why and why not?

I don't think it's really useful to attend prenatal classes at all. My husband and I did not attend any of these classes. Information on how to care for could be easily found online and even on youTube. Of course, friends with babies did teach us the essential of taking care of a baby. But if you are still considering different type of birth methods, you might considering hiring a doula who will be able to help more than the prenatal classes provided by the hospital.
