Is there any truth to the old saying “If momma ain’t happy, ain’t nobody happy”?

Overall, 60 per cent of young people say they are ‘completely satisfied’ with their family situation but in families where the child’s mother is unhappy in her partnership, only 55 per cent of young people say they are ‘completely happy’ with their family situation â compared with 73 per cent of young people whose mothers are ‘perfectly happy’ in their relationships.

And:

The research also finds that having older siblings is not related to children’s happiness with their family, but having younger siblings in the household is associated with lower levels of satisfaction, and this effect is greater the more younger siblings there are in the household. But relationships with parents are even more important than relationships with siblings. Only 28 per cent of children who quarrel more than once a week with their parents, and don’t discuss important matters with their parents are completely happy with their families.
