There is no specific time frame for how long fetal hiccups usually last in late pregnancy, it is the habit of each fetus, and fetal movement is also related to the fetus’ personality and sleep habits. Pregnant women only need to pay attention to the difference between the fetal movements and the previous ones, whether the number of times or the intensity and frequency of fetal movements are the same as before, it is a normal fetal movement. Pregnant women do not need to consider whether the fetal movement is the same as others, there is no strict standard for fetal movement, the key is to compare it with their usual. The fetal hiccups are only one kind of fetal movement, and it is not possible to accurately determine whether the fetal movement is caused by fetal hiccups or fetal limb movement just by the fetal movement performance. The fetal hiccups are only one kind of fetal movement that is widely circulated among pregnant mothers, and it is not used as a medical basis to determine whether the fetus is normal or not. The two-hour counting method is to choose a time period when fetal movements are more frequent, such as at night, after meals, when the pregnant woman is resting and focus on fetal movement counting, and if you can feel at least 10 fetal movements within 2 hours, it is more normal. When counting the fetal movements, pregnant women must concentrate to avoid missing the count. The 12-hour counting method is to take the number of fetal movements in the morning, noon and night for one hour each and multiply it by 4, which is 12 hours of fetal movements, usually 30-50 times/day is normal.
