Dear Willow,
The loosening you describe is due to an enzyme released during pregnancy
called hyaluronidase.  I don't know how long it would continue to be released
after the birth as it is there to loosen cartilage for the birth.  I have had
mothers who have had a hip put out from birth especially from a posterior
baby who works the area while turning.  Postpartum massage and Chiropractic
adjustments have elliminated the problem without having to use drugs that
might not be conducive to breastfeeding.
Hey something I really know about!! : )
