What's the Difference Between Private and Group Childbirth Prep Classes?

In a typical childbirth prep classes, how many hours a time with you. At my my studios, only four hours. But there are others that'll do six to eight hours. And some of my couples who have either are too late in the game, and they're like, so were do next week? O at can squeeze into the group class? Or we just know that they want kind of that very individual experience. Ey have lots of questions.
