Did you take any classes during pregnancy/early parenthood?

We just signed up for our 5 session birth preparation (lamaze) class series, but are curious if we should load up on any more. I'm interested in a breastfeeding class, as well as one on basic infant care (swaddling, diapering, feeding, establishing sleep/wake routines, etc)

If you took any formal courses in preparation, do you feel they were worth the money, and helpful for those first few months?
