If genetic problems are found, they should be stopped as soon as possible. 4. Ensure that pregnant women have adequate nutrition and a balanced diet. 5, pay attention to disease prevention, careful medication during pregnancy. Don't use antibiotics, sedatives and hormones indiscriminately, which is an important aspect to avoid fetal organ malformation. 6.

Pregnant women should have regular prenatal check-ups. Prenatal examination can correct fetal malposition as soon as possible and avoid dystocia.
