A study shows that the secret of domestic bliss is having two daughters, the Daily Mail reports.

Researchers found that two girls are unlikely to fight, will play nicely together, and rarely annoy their parents.

They also make little noise, seldom ignore each other and are more likely to confide in their mother or father, scientists claim.

But doubling the number of daughters is a recipe for disaster, with parents of four girls the least happy and reporting an average of four fights a day.

家有两女最幸福

       据英国《每日邮报》报道，研究发现，家庭幸福的秘诀在于拥有两个女儿。

       研究人员称，两个女孩不大可能打架，她们能很愉快的一起玩，很少使父母生气。

       她们还不怎么吵人，很少会无视对方，而且更可能和父母推心置腹。

       但是如果女儿的数量翻倍的话，就会带来“灾难”。有四个女儿的父母感到最不幸福，因为女儿们平均每天就得打4次架。
