Later, Xiaohua found out that she was accidentally pregnant. The couple, who had not much savings, worked hard and wanted to save some milk powder money for their children. < / P > < p > Xiaohua works in a factory, which is filled with a lot of bacteria and chemicals every day, and the air quality is very poor. In order to make more money, Xiaohua didn’t rest during her pregnancy. < / P > < p > the birth of the child not only did not bring joy to the family, but also made it worse for the poor family, which made Xiaohua regret. < / P > < p > in general, Down’s children are mentally retarded and can’t take care of themselves. In addition, as they grow up, their body will be accompanied by some other complications, which will bring great burden to their families. < / P > < p > when pregnant women live or work in such an environment for a long time, these harmful elements will be absorbed into the body, leading to fetal chromosomal abnormalities, and the possibility of giving birth to Down’s baby is great. < / P > < p > nowadays, many pregnant mothers are accidentally pregnant, and even find out after 2 or 3 months of pregnancy. In this process, medication will occur because of physical discomfort. < / P > < p > the effect of drugs has a great impact on the development of the fetus.
