For the host , I think it is false about giving birth, because there is no such fast birth, and some have a few or even more than ten hours. , The film is finished in less than 2 minutes. I would rather believe that it was the director who arranged this for the rhythm of the film. But it feels fake.
Moreover, when the umbilical cord is not cut at the time of birth, the child is still breathing through the umbilical cord. After being cut, it needs external stimulation before changing to cardiopulmonary breathing (usually a spanking on the baby's buttocks). In the film, the child would cry when he was born, and only then did he think of cutting the umbilical cord. I don't know if the director does not have this aspect of life or other reasons. In short, this period is inaccurate.

In fact, I personally think that the filming is quite real. "Because the childbirth is not so fast, some have a few or even more than ten hours." What you mean is the whole process. The whole process of delivery has 3 stages, also called 3 stages of labor.

1. The first stage of labor, that is, the period of dilation of the uterine orifice. Refers to about 12-16 hours from the beginning of regular contractions to the opening of the uterine orifice, about 12-16 hours for primiparas, and 6-8 hours for menstrual women. During this period, the uterus contracts regularly and the uterine opening gradually expands. The mother often feels backache and a feeling of falling abdomen. During the first stage of labor, women should pay attention to rest, eat small amounts of easy-to-digest and nutrient-rich foods, and urinate regularly to prevent the decline of the fetal head. Before the opening of the uterine orifice is 3 cm, you can walk around in the delivery room. After the opening of the uterine orifice is 3 cm, you can lie on the left side of the bed as well), so as to prevent the enlarged uterus from compressing the inferior vena cava and affecting the blood supply to the placenta.

2. The second stage of labor, that is, the delivery period of the fetus. Refers to the period from the opening of the uterine orifice to the delivery of the fetus. The primipara is usually 1-2 hours. In this period, the uterine orifice has been opened, the fetal membranes have been broken, and the duration of contractions is extended by 50 seconds to 1 minute, with an interval of 1 to 2 minutes. A sensation of bowel movement during contractions. At this time, you should take a deep breath and try to hold your breath downwards to increase abdominal pressure and assist the delivery of the fetus. The mother suddenly felt relieved after the fetus was delivered.

3. The third stage of labor, the 8p placental delivery stage, refers to the process from delivery of the fetus to the discharge of the placenta. Generally no more than 30 minutes. After the fetus is delivered, the uterine contractions temporarily stop, and soon it restarts to promote the discharge of the placenta. At this time, the mother only needs to apply a little abdominal pressure. After the placenta is delivered, the parturient can relax and rest. The birth attendant must check whether the placenta and fetal membranes are intact, and whether there are lacerations in the birth canal, and deal with them accordingly. At this time, the whole process of childbirth is completed.

In the previous movie, it took only two minutes for the fetal membranes to rupture to the delivery of the fetus, which is rare but also present in primiparous women.


Crying when a fetus is delivered is a manifestation of breathing after being stimulated by the external environment. After the fetus is delivered, the placenta has begun to peel off, and there is no "umbilical cord breathing" at all.

However, the expression of the obscure theme is destined to not be a too successful commercial film.
