it's not uncommon for babies to be in a breech position (feet or buttocks first) at various points during pregnancy. However, by the time you reach full term, most babies will have moved into the head-down position in preparation for birth. According to various studies, around 3-4% of babies are breech at term.
There are still chances that your baby could turn to the head-down position before your due date, although the likelihood decreases as you approach the due date. Some methods like the ECV (External Cephalic Version), certain exercises, or even chiropractic techniques are used to encourage the baby to turn.
