Breech Birth occurs when a baby is not positioned to be born with the head first.
There are three kinds of breech presentations. The most common is called the frank breech, also termed as extended breech; it is when the baby is born with the bottom first with the knees straight and the feet near the head. Most doctors prefer to deliver babies in this position via caesarian section since vaginal delivery poses several risks.
A complete breech, also termed as flexed breech, is when the bottom goes first with legs bent at the hips and knees. This position makes the baby appear to be sitting crossed-legged.
The third type is the footling breech which happens when the feet (both or one) go first.
