I took it, and honestly... it wasn't that great. I love the teacher, but I pretty much knew all the stuff in the literature that was handed out. It felt like kind of a rush job. All I really remember learning was "brush brush bam" is how you get the baby to latch, lol! What I did not learn about is how to tell if your baby is tongue-tied, and what to do about it.... which turned out to be exactly what I really, really needed to know.
If you need information on breastfeeding basics, then I'd go ahead and take the class. If you've already done a bit of research on your own regarding general breastfeeding issues, it might be a waste of your time.
I took the class at A Nurturing Moment (it was free since we took the Bradley Method Class there). I did give birth at Crestwood, though, and the head lactation nurse, Jane Mitchell, was my lactation consultant. I really loved her and all of the staff at Crestwood. In fact, about 4-5 weeks post partum, when I was experiencing a second round of mastitis, the nurses gave me Jane's cell phone number since she was out that day and she gladly spoke with me concerning my problems with nursing.
So, I guess all of that to say that even though I didn't take Crestwood's nursing class, I did really appreciate the concern and care of the teacher of the class.
Hope that helps!
