Definition of Breech birth

Breech birth: Birth of a baby with the buttocks, rather than the head, emerging first. Breech birth is more likely to cause injury to the mother or the infant than head-first birth. In many cases a baby in the breech position can be turned before delivery by using repeated, gentle massage.
