Pregnant women can make their babies change their movements by listening to music, doing proper exercise and eating some food before the examination. 1. Listening to music: Pregnant women can listen to some soothing fetal music, which can make the baby move with the rhythm of the music and help the baby to be active in the examination. 2. Doing exercise properly: Pregnant women can do some exercise properly, such as walking, climbing stairs, etc. Usually the baby’s posture may change after proper exercise. 3. Eat some food before the examination: Pregnant women can eat some nutritious food before the examination, such as milk, bread and so on, which can make the blood sugar level in the pregnant women’s body increase and make the baby more energetic. If the baby’s posture still doesn’t change through the above methods, it is recommended to consult a doctor in time and take appropriate treatment measures under the doctor’s guidance.
