To form a fetus, the first step is to have a healthy egg and sperm combine to form a fertilized egg. After the fertilized egg successfully implants, it develops into an embryo and eventually becomes a fetus. After being carried by the mother for ten months, the fetus can be born smoothly. Some new expectant mothers, due to their lack of understanding of the fetal development process, asked if the fetus has bones?
Of course, fetuses have bones, but their bones do not begin to develop until the fourth month of pregnancy. This is because from mid pregnancy, the fetus enters a period of rapid growth, and the main bones of the fetus begin to undergo normal calcification or ossification, such as the skull, limbs, spine, and teeth.
Therefore, when pregnant women enter mid pregnancy, expectant mothers should pay attention to calcium intake and supplement appropriately in order to promote fetal bone development. If sufficient calcium is not consumed in a timely manner, mild calcium deficiency may cause symptoms such as leg cramps, limb numbness, and insomnia in expectant mothers. Severe calcium deficiency may affect the baby's bone development and ultimately lead to the occurrence of congenital rickets.
Starting from mid pregnancy, the daily intake of calcium for expectant mothers should be 1000-1200 milligrams. It is generally recommended to supplement through diet, such as eating more dairy or soy products, which are good calcium supplements. In addition, if you want to increase calcium absorption and intake, it is best to consume protein and vitamin D foods together.
