A breech presentation is defined as the condition in which the baby is in longitudinal lie and the podalic pole presenting at the pelvic brim with the head occupying upper pole of uterus. A breech birth is the birth of a baby from a breech presentation. In the breech presentation the baby enters the birth canal with the buttocks or feet first as opposed to the normal head first presentation. In breech presentation, fetal heart sounds are heard just above the umbilicus.
A breech position means that your baby is in a bottom-down position inside your womb. Usually your baby will settle into a head-down position in your pelvis around the eighth month of pregnancy. A head down position of the baby inside your womb is called a vertex or a cephalic position.
When labor, nearly all (96 per cent) babies are lying head down in the uterus, but a few (about 3-4 per cent), will settle into a bottom-first, or a breech position.
