Down Syndrome can’t be prevented especially once the women becomes pregnant. This is because the baby has already been formed and Down Syndrome is a genetic disorder where the child has already formed the third chromosome. However, there are certain things that the mother can do to lessen her risk of having a baby with Down Syndrome. She could have babies earlier in life.
If she waits until later like in her 40s, she stands a greater chance of having a baby with Down Syndrome. Also, if she already has a child with Down Syndrome, she stands a greater chance of having another baby with Down Syndrome. Therefore, it can’t be prevented but steps can be taken to lessen the risk.
