Fetal movement 태동
- A baby from the moment of fertilization to the 8th week of pregnancy is called a fetus or embryo.
- At 7-8 weeks of pregnancy, the fetus can live in the womb, but the pregnant woman herself cannot feel the fetus live at all.
- However, it is possible to detect that the fetus begins to move from the 7th to 8th weeks of pregnancy with an ultrasound test. In this way, the movement of the fetus in the womb is called prenatal (胎動).
- The baby in the womb from the 8th week of pregnancy until birth is called a fetus. At the 3rd month of pregnancy, the fetus rolls in the womb, performs tricks, licks, hurts, frowns, and sucks.
- Most pregnant women themselves can certainly feel the fetus playing and exercising in the womb starting at around 4-5 months of pregnancy, and rarely at 6 months of pregnancy.
- Some prenatal women who felt the fetus moving for the first time express their birth by saying, “It seems like a gentle wave is hitting in the abdominal cavity,” while some pregnant women say,
- “The first feeling of pregnancy is similar to the gas movement in the intestine.” In general, the multipara can detect the early birth than the first birth.
- It is common for the fetus to become weaker at first, but as the fetus approaches full term, the movement of the fetus becomes stronger and stronger.
- For example, in the 7th to 8th months of pregnancy, the fetus in the womb kicks the mother’s abdominal wall with her feet, hits her head, presses the bladder, pushes the ribs, etc.
- Depending on the number of weeks of pregnancy, the fetus plays with a bigger motion.
Stethoscope to hear the beating of the fetus’s heart
- Nowadays, it is common to hear the sound of the fetus’s heartbeat on a fetal monitor.
- The fetus does not always play and exercise in the womb. Even the fetus begins to develop a pattern of life in the womb that sleeps and wakes up according to the 24-hour day and night cycle.
- Most of the fetuses are active for 1 to 2 minutes starting around the 9th week of pregnancy and then develop an intrauterine fetal life pattern, such as rest.
- In other words, a certain pattern of fetal movement begins to develop in the fetus. As explained above, the fetus also has a pattern of sleeping, waking, and playing every day. In particular, at 36-38 weeks of pregnancy, there is a separate time for active physical activity like newborn babies, a separate time to stop physical activity for a while and a quiet time off, and the time to sleep well maybe discerned to some extent during the day.
- And it is said that the fetus can fall into a state of paradoxical sleep (REM, REM sleep) and dream.
- Studies have shown that the fetus’ daily activity is divided into quiet sleep, very quiet sleep, very awake play, and quiet play.
- Depending on the fetus, they play a lot for a few days and exercise a lot for a few days, then they play very little and exercise a little for a few days, and then they play very quietly for a while, and then they play and exercise a lot again for a few days. In the evening, when the surroundings are quiet, most pregnant women can detect the pregnancy more.
- You can also detect a decrease in a prenatal movement when lying down or relaxing. The intensity of pregnancy varies according to the emotions of pregnant women, physical activity, and food intake.
- Until fetal descent occurs, the bigger the fetus, the louder it plays and exercises. When the fetus moves in the womb, the pregnant woman’s abdomen can also be seen with the naked eye.
- This phenomenon is often said to be played by a baby in the womb. The fetus plays with small arms and legs in the womb, stretches and folds, moves the neck from one side to another, and withdraws and unfolds the torso.
- However, the fetus does not always play and exercise.
- Don’t worry if your baby doesn’t play for a while. In general, after getting closer to the expected date of birth and the fetus descends, the fetus usually plays less than before. Copyright ⓒ 2014 John Sangwon Lee, MD., FAAP
