When parents fight, children are usually affected. If parents can resolve their conflicts without behaving violently toward each other or speaking harshly, children are not as disturbed. They learn that conflicts can be resolved peacefully and relationships preserved, even when people strongly disagree with each other. When parents lash out or give each other the silent treatment, however, children are affected in many ways.

There are different types of issues that might happened:
1) Sleep issues. Researchers studied 350 families with babies who were 9 months old at the beginning of the study. In the families with a high level of marriage problems, the babies had more sleeping problems when they were 18 months old, either having a hard time falling asleep or staying asleep.

2)School issues. Researchers studied a group of children for three years, beginning when the children were 6 years old. The children who reported concerns about how their parents got along with each other were at significantly higher risk for having problems paying attention; the problems began one year after the children reported their concerns.

3) Problems in a teen years.Unfortunately, a bad relationship between parents can affect a child for years.
The children experienced more depression, anxiety and emotional insecurity. The primary author of the study Mark Cummings, professor of psychology at Notre Dame, said in an article for The Star that children were especially at risk when “their emotional insecurity increases as a result of the conflict.”
