St.Jude's Fullerton - Prepared Childbirth Class

I'm getting a lot of feedback from everyone on what I should and shouldn't do (go figure) and I'm curious to see if anyone has taken the Prepared Childbirth class at St. Jude's or affiliates. My husband's co-worker says it was a waste of time and my friend also said I don't need to take it.... While I'm just so not sure on what to do! There aren't any reviews online and my husband said he'll do whatever I want to do.
