A link between labor and belly dancing?

Some belly-dance movements mirror those of labor. The idea is that the pelvic gyrations help disperse the pain of contractions, orient the fetus and propel the baby into the world. In early labor, when contractions are relatively mild, the expectant mother may find comfort in dancing slowly and hypnotically, using hip circles, crescents and figure eights. As labor gets more intense, the movements may progress to a rapid rocking of the pelvis from side to side — a technique known as the shimmy — to help position the baby correctly and relax the pelvic floor. In the final phase of pushing, a full body undulation known as the camel roll can help the baby move into the birth canal.
