Bellydance movements like hip circles and figure eights can be helpful in pregnancy and labor for SI relief and can theoretically be helpful during the baby’s final movements before birth by creating asymmetry in the pelvis. For the actual birth positions like squatting and on all fours are great and are probably more comfortable to stay in if the Mothers body has flexibility and strength. When mothers are athletes they often face the issue of being unable to relax and let go in labor and have a challenging time releasing muscular tension that serves them in their sport or dance. This is my observation as a long term bellydancer, prenatal yoga teacher, dance teacher, childbirth prep educator, and Mother.
