Towards the end of your pregnancy, the baby almost always turns down with the head. A few present as breech, about 3%. Most babies will then engage with the head in the pelvis. Some women feel that they have to urinate more often and for some it is more difficult to get up from a deep chair.
When the baby descends into the pelvis it means that it’s a good fit. But baby’s that don’t descend in the pelvis the last weeks, usually also fit well. They descend during labor. During labor, your pelvis gets wider and becomes more mobile. This is caused by the hormones that play a role in labor.
Nervous doctors will sometimes suggest: “That baby is very large. Let’s induce you to prevent the baby getting even bigger, otherwise he may not fit through your pelvis. “
This makes most pregnant women anxious and anxious women birth with more difficulties. A parasympathetic process is disrupted already. Be aware that estimating the weight of the baby is very unreliable. A 10-15% difference is possible. Whether it is estimated with an ultrasound or by hand.
When a woman is in labor, it is important to Monitor to make sure the contractions are effective. When contractions are effective birth will progress smoothly. And with no effective contractions, it is wise to Correct on time.
When labor is induced, it is much harder to get effective contractions. Your body is not ready and your pelvis does not respond properly to the hormones of birth. Moreover, with an induction you are usually in bed, with or without an epidural. Thus, a situation is created in which the odds that the birth ends in a Caesarean section are increased enormously. The reason for the Caesarean section is then written as: the baby was too big, does not fit through the pelvis. But in reality it is a failed induction.
Induction is one of the most abused interventions in obstetrics. Moreover there is no evidence whatsoever that the outcomes for mother and baby will get any better with induction for large baby.
Even when you give birth to a big baby we see that for women having effective contractions the weight of the baby is not that important. Many women have given birth easily to baby’s as large as 5000 g.
If a baby is really too big for the pelvis, and the mother has effective contractions, we see that dilatation stalls after 7 cm. The baby is not wedged deeper into the pelvis. The first step then is to Correct. If that is not successful after 2 hours it’s time for a cesarean section.
Approached in this way, we see that really very few caesareans are necessary for a “too big baby.” And we see a lot of surprises on the scale of children estimated to be larger or smaller.
