The breech position in early and middle pregnancy is normal and needs no special attention. When the fetus is still in breech position at 30 weeks, it is necessary to take corresponding measures to correct it, including the following: 1. knee-chest position: can be done at home, i.e. the pregnant woman kneels on the bed surface and keeps her chest as close to the bed surface as possible for 15 minutes, 2-3 times a day, and can be reviewed after a week; 2. laser treatment and external rotation of fetal position: both need to go to hospital for treatment. All the above methods have risks of placental abruption, intrauterine distress and preterm delivery, so once abnormalities are found, you should go to the hospital immediately.
