Once baby flips head down
A common question here at Spinning Babies is, "Now that my baby is head down, should I continue the exercises?" Balance only improves with balancing.
Give yourself a few days of brisk long walks. Wear a pregnancy belt. Do sidelying release on both sides daily for a while and then 2x a week. Keep balancing. You've done good work, but keep going so tight muscles don't return and add their mischief again.
After that if your baby is favoring your right side, firm more on the right than left, resume the 30-second forward-leaning inversions but not the breech tilts. Continue with the pelvic stabilizing exercises and psoas release, and any myofascial releases (standing or abdominal release).
