I'm 17ish weeks, and my doctor just told me to start checkin' out my hospital's baby classes (a "What to Expect"-type class, one about breastfeeding, an infant CPR class, and a general baby care course). Each has a fee, but DH and I know nothing about any of those things, so we're planning to check a few out.
Did you take classes? And if so, when? I read somewhere that 20ish weeks would be an OK time, but then did you forget all that stuff when it came time to, you know, actually have a kid?
