Why do some people say that twins are difficult to raise?
There is no scientific basis for twins to be the most difficult to raise. There is a myth in ancient China that one twin will die, both of them are hard to feed, and the twins are not good. In fact, these statements are completely unfounded. As far as the current situation is concerned, the live birth rate and survival rate of twins are still very high, not lower than that of a twin or a same-sex twin.
Pregnant women with twins will have more serious pregnancy reaction, and the growth and development of two fetuses will make the space in the uterine cavity smaller and the body organs more oppressed. Therefore, women who are pregnant with twins are more likely to vomit, nausea and nausea will be more intense in the first trimester, the frequency of urination will be greater, and the growth of stretch marks will be more serious.
Boys and girls twins
Twins, a proper term, refer to twins of different sexes, that is, identical twins. The probability of occurrence is very small, generally around one thousandth to five thousandths. Twins are divided into identical twins and identical twins. Twins are twins of different sexes, that is, identical twins. Only in this way can twins appear, and identical twins have a 50% chance of becoming twins.
The characteristic of identical twins is that the blood circulation of the two fetuses communicates with each other through the placenta, so identical twins have exactly the same blood type and gender, and their faces are difficult to recognize. Giving birth to twins is related to genes, races, drugs and so on.
