Wikipedia
A breech birth occurs when a baby is born bottom first instead of head first. Around 3-5% of pregnant women at term (37–40 weeks pregnant) will have a breech baby.
Most babies in the breech position are born by a caesarean section because it is seen as safer than being born vaginally.
As most breech babies are delivered by caesarean section in developed countries, doctors and midwives may lose the skills required to safely assist a women giving birth to a breech baby vaginally. Delivering all breech babies by caesarean section in developing countries may be very difficult to implement or even impossible as there are not always resources available to provide this service.
