A<unk>  is when a baby is born bottom first instead of head first, as is normal. Around 3–5% of pregnant women at term (37–40 weeks pregnant) have a<unk>  baby. Due to their higher than average rate of possible complications for the baby,<unk> s are generally considered higher risk.<unk> s also occur in many other mammals such as dogs and horses, see veterinary obstetrics. Most babies in the<unk>  position are delivered via caesarean section because it is seen as safer than being born vaginally. Doctors and midwives in the developing world often lack many of the skills required to safely assist women giving birth to a<unk>  baby vaginally. Also, delivering all<unk>  babies by caesarean section in developing countries is difficult to implement as there are not always resources available to provide this service. OB-GYNs do not recommend home births if a<unk>  is expected, even when attended by a medical professional.
