Rsearchers have found that 74% of mothers and 70% of fathers admit to having a favourite child – and children say there is a bias towards the eldest one.
Sociologists from the University of California performed a study which found the first-born appears to get preferential treatment, and that most parents have a favourite child.
While the parents did not reveal which child was their favourite, the study found that youngest and middle children thought there was a clear bias towards the eldest child.
This knocked their self-esteem.
The researchers found actions as simple as being the first to complete a child made the eldest feel confident and assertive.
