First of all, not all girls want to be mothers.
Because mother means responsibility, she needs to undertake many things. Some girls have no sense of responsibility for the time being, and don't want to give birth to a baby early, and then take on the responsibility of raising him. I have met many mothers who gave birth to their children without care. They usually only care about their own play and leave their children to others for adoption, but when they grow up, they are actually very indifferent to the word affection.
The second point may be because of work.
Some women don't want to have children because they are naturally workaholics and don't want to waste their working time because of having children. What they want is how to upgrade, how to earn higher wages, how to make their lives better and better, and their performance will definitely be affected after having children, so they will choose not to have children for the time being.
The third point may be because of the fear of the pain of giving birth and the shape of the body.
In recent years, with the popularity of the Internet, I have also seen many treasure moms sharing on some apps. It is said that the pain of giving birth is very, very painful. Some young women will be afraid to have children when they see their sharing, and their health will be out of shape for a long time after giving birth, and they may even recover. Therefore, many women who love beauty are reluctant to have children.
