Hey when is your due date ?
I think it's helpful. Most hospitals have it weekly and you can just sign up. It's nice to know where exactly you need to go when in labor. And in case if you need a c-section or something, you won't be so frightened. And it's good to go so you can ask any questions you have. For example: how many people can be in the Delivery room? Can you have a water birth? Visiting hours? What to bring in a hospital bag? How dilated you need to be admitted? Etc.
It's not necessary.. I never did one..
