First of all, we have to say that we have to look at four aspects: productivity, birth canal, fetus, spiritual and psychological factors, first of all, this spiritual and psychological quality, the mother must have enough understanding and confidence in childbirth, this is the premise, the first.
The second is that there is no problem in the birth canal, including the bone birth canal and the soft birth canal without any problems, and then the power of childbirth is changing, I can use medical means to help you remove during pregnancy, purely from the problem of the child, the problem of fetal position, the problem of the size of the child.
In the past, we thought that it was twins or multiple births, either absolutely can not be born, or to look at the fetal position, mainly depending on the fetal position and the size of the child, if this fetal position is both the head, or the first is the head and the second is the buttocks, in the past we thought that the first is the head, the second is the buttocks, this can be born.
Or that the first is the buttocks, the second is the head, because after coming out, I am afraid of the fetal head staggering, the two chin chins are hooked together, can not give birth, that is, the way of childbirth We say twins, now everyone's delivery technology has improved, midwifery technology has improved, the first fetus is gluteal, and then there are no other maternal and child complications, you can choose vaginal delivery.
It is the simplest sentence, the first child is the first position, the first child is the head first, it is the first position, I can give birth, this is the meaning.
