lovemypups1:I've been on mine every night for weeks with no results.
Ive only heard of one mom on this board whose gone in to labor right after bouncing, but that couldve been a fluke. The biggest thing about bouncing/hip rolls is that it opens your pelvis up to help the baby come down some more and to help your pelvis stretch in preparation for delivery. It wont necessarily MAKE you go in to labor if you arent already ready, but it can help make labor quicker and pushing quicker once you do get to that point. It's also a good tool to use DURING labor to help bring baby down quicker. Also a good tool to use if youre having back or hip pain.
Hope that helps, but most "natural induction" techniques are really not good for more than helping your body out once you actually do go in to labor, many dont actually PUT you there.
