I went to a "babywearing" class on Saturday offered by a local parent through her business (http://www.thebabyhammock.com/). The class was really more of a demonstration of different carriers, slings, and wraps. It was helpful, although I am neither coordinated enough nor mechanically inclined to naturally figure these things out myself (hence why I took the class).
Anyway, for most of the class, the instructor used a doll to demonstrate how the different carriers work. But, at one point Cassandra was her stunt baby! I must say the child is a natural in front of crowd (of four total). She cooed, burped, even farted. I was so proud.
