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

I did not attend any prenatal class, but a friend who attended a ParentCraft workshop (few sessions over a few weeks) said that she couldn't really remember most points. Although she was taught how to bathe the baby at the workshop, she ended up learning from her confinement lady as she was afraid to handle the baby on her own at first. However, for myself, I love children and have been reading up on parenting since I was a teenager, so I didn't think it was necessary to attend the classes. All the theory can be acquired online, but you'd need to handle an actual baby to be aware of the challenges. I would think it is more effective spending an entire day at someone's house with their newborn than to attend a few weeks of lectures.
