I think the classes were helpful. They weren't all that fun, and dh hated them. But we learned a lot. It was helpful in different ways. My labor was much different than what they described because I was induced. So the patterns and breaks they described weren't what I experienced. But they discussed pain relief, my specific hospital rules as far as visitors, eating during labor, baby being in with you in the room vs nursery, aids that the hospital encourages during labor, a look at the hospital suites and what specific things in the room were for, what to expect after delivery and what the hospital provided for us.
I'm not doing them with this baby since we have been through it now. But as a first time mom and having a husband who didn't have a clue about the labor and delivery part I was glad we spent the time and money.
