I had the same problem with my first born even though i was told i have "amazing child baring hips" my son got stuck in my pelvic bone and ended up in emergency c section, and he came out with read marks on his head from where he was stuck and still has them, hes 5 years old now! As it turns out i have a really tiny pelvic bone even though i have child baring hips, i was told that this baby is also going to have to be done by c section because of my pelvic bone being super tiny.
I could've explained that a little more technically..
your pelvic bone is just that - a bone. it can't be changed unless it was physically broken. people do squats and stuff to make it APPEAR that their pelvis has changed, but the hips (hip BONE) remains the same. the muscle/fat/tissue just changes.
I've read stretching and stuff is the only thing that MAY help you with labor.. I wish you luck though!! ((:
Ur pelvis seperates at the front and pregnancy helps it naturally with the joint relaxing hormones that are produced but if it was too narrow with ur first still Idk thatd u have a better chance 2nd time just remember however baby gets here the safest is what matters most sorry momma
being an x-ray tech., I can almost say I'm 100% you can't change the width of your pelvic bone.. that would literally hurt, a lot, probably break lol never heard of that whatsoever.. it's just something you're born with.
I've always been told I had "child-bearing" hips/pelvis, but who knows.. this baby may tell me differently in October! lol
