The onset of fetal motor activity
Usually the first movements of the fetus are felt after 15 weeks of pregnancy. And those who are preparing for repeated childbirth, feel them earlier than those who wait for the first baby. Primordial, most often, first hear the first tremors closer to 20 weeks. But this does not mean that the child did not move at all until this moment. In fact, starting at about 7 weeks, the first movements appear. But since the fetus is still too small, it does not touch the walls of the uterus, which means that it does not make itself felt. At the first ultrasound screening, you can see how the baby makes movements with his limbs.
Closer to 14-15 weeks of gestation, movements become more active. This is explained by the fact that the child has grown, his limbs have become familiar to us. The crumb floats in the liquid, pushing away from the walls of the uterus. But because of its small size, Mom can not clearly feel such jerks. Some women, listening to their body, note some unfamiliar signals, but can write it down to the work of the intestines or muscle tension. This is one of the reasons why the miscarriages can feel the movements in 15-16 weeks. They are already experienced mothers, they know exactly what to expect, since they are already familiar with this phenomenon. In addition, their abdominal wall is somewhat stretched and sensitive, which contributes to a better perception of the activity of the baby.
Also, you should know that full women will be able to recognize the movements of the crumbs later than those that have low weight. A thin expectant mother, who is expecting the first birth, also has every chance of feeling fetal movement closer to week 15.
Norm of motor activity
The behavior of the baby, the way it moves, is important for assessing the course of pregnancy. Some doctors can ask a future mother to keep a small diary in which they will record the movements of the baby.
The child is in constant movement around the clock, except for the time when he is sleeping. After 15-20 weeks of pregnancy, the number of perturbations is about 200 per day. By the third trimester, their number increases to 600. And then the child becomes more difficult to actively move in the womb because of its increased size, because the number of shocks is reduced. It is worth noting that the mother in any case can not hear absolutely all the movements.
The following factors influence the activity of crumbs:
- the change in the behavior of the baby can be associated with external stimuli, for example, sounds;
- If the future mother is in a state of stress, the baby moves more intensively;
- in a state of rest, a woman feels stronger the blows and tremors of the baby;
- children behave more actively if future mothers experience hunger or ate sweets;
- When the pregnant woman is in a pose that causes discomfort, the baby can signal itself with painful strokes;
- the night activity of a child is most often noted.
