Head lgst part: Head down vaginal deliveries are more likely to go smoothly because the head has engaged in the pelvis & had time to mold into a workable size to come down the birth canal. Since it is the largest body part, coming last may not allow time to mold or it may just be too big.I have sat in on deliveries where we had to push baby back in to get it out the top by csection.

Head entrapment.: In a breech presentation, the most important part of the fetus (i.e. The brain) delivers last. The risk is that the head gets entrapped by the cervix and maternal lower birth canal and the brain gets permanently injured (or the infant dies) as a result of attempted vaginal birth. Do not attempt!

Very risky: Among breech babies, >50% switch to cephalic at 32wks, and it even happens at 38wks spontaneously. OBGYNs can perform a VERSION to flip baby at term, but DON'T TRY @ HOME. All breech babies should be delivered via C-Section b/c the risk of vaginal delivery is too great (head entrapment and fetal death due to cord compression). Only in RARE situations are vaginal deliveries performed.
