When is the critical period for fetal ear development?

When a woman just becomes pregnant, the fertilized egg will implant in the uterus, and then begin to develop in the uterus, from a tiny fertilized egg to a complete fetus. This process is very complicated, and such changes are also amazing. So, usually, when do the fetus' ears begin to develop?

Critical period of fetal ear development:

1. Basic organ development period

After the fetus implants in the mother's body, it enters a stage of rapid growth and development. In the first month of pregnancy, the fetus's limbs have begun to develop. In addition, the fetus's brain, spinal cord, oral cavity, and digestive tract have also gradually begun to form. At this time, pregnant mothers need to supplement some calcium, iron, copper, and vitamin A to meet the needs of fetal development. Pregnant mothers can eat some fish, eggs, green vegetables and cod liver oil to meet the nutritional needs of the baby's growth and development.

2. Facial organ development period

In the second month of pregnancy, the fetus' lips and ears have begun to form. At this time, pregnant mothers should stay away from radiation, maintain a good mood and not get angry easily. In addition, pregnant mothers need to consume more protein-rich foods to meet the needs of fetal growth and development. During this period, it would be a good choice for pregnant mothers to eat milk, eggs and beans.

3. Hearing development period

Generally speaking, the fetus begins to have hearing in the fourth month of pregnancy, but at this time the fetus is not very sensitive to external sounds. At this time, pregnant mothers should start to stay away from noisy places. The most important thing is not to place headphones and speakers directly on the abdomen for prenatal education of the fetus, which will seriously affect the hearing and physical development of the fetus. In addition, if the pregnant mother is exposed to harmful substances such as formaldehyde, gasoline, benzene, etc. during this period, it will also affect the hearing development of the fetus.

The first three months are an important stage for the development of brain cells. The mother's hormone secretion and nutritional status will affect the growth of the fetus. Although the nutrition absorbed by the fetus at this stage is limited, it is still necessary to pay attention to balance and not allow yourself to have abnormal eating habits or let bad habits intervene (such as smoking, drinking, drug addiction, etc.). Basically, you can achieve a good condition.
