Belly Mapping

Spinning Babies is a cool site. It is a "unique, step-by-step approach to Optimal Fetal Positioning. Certain positions of the baby make labor easier than others."

There is a section called Belly Mapping which a mother can use late in pregnancy to try to determine baby's position on her own. I've been poking around a bit and I haven't quite got it figured out, but it's nice to have a resource to reference.
