Throughout your pregnancy, your baby is free to move around inside the womb and can change position many times. They might be head down, sitting up, lying sideways... and change again. Because of this, the position found during an appointment does not necessarily mean that will be their position at birth.
As your baby grows and the space inside gets tighter, they are more and more likely to be found in a head-down (cephalic) position. However, around 28 weeks, about 1 in 5 babies may still be in a breech position (sitting up). If this is the case for you, please know that by the end of pregnancy only about 3 to 4 in every 100 remain in this position.
