Answer :

As babies they may reach growth and development milestones later than other children do. These may include rolling over, sitting, standing, walking, and talking. As children in this age group, health problems and developmental disabilities can lead to behavior problems. For example, a child may develop oppositional defiant disorder which is a disorder in a child marked by defiant and disobedient behavior to authority figures. They may get this disorder because he or she does not communicate well or understand others' expectations. As teens puberty starts at about the same ages for teens with Down syndrome as for other teens. They may face social difficulties and vulnerabilities such as abuse, injury, and other types of harm. They may also have a hard time handling strong emotions and feelings. Sometimes these struggles can lead to metal health problems, especially depression which could lead to self-harm or even suicide. As adults men with Down syndrome most often are sterile and cannot father children. Many women with Down syndrome can have children, and they usually have early menopause which is a natural decline in reproductive hormones when a woman reaches her 40s or 50s but in this case it would usually happen early in Down Syndrome women.
