The order in which you were born will have an impact on relationships all throughout your life, relationship expert Jen Kirsch told CityNews on Monday.

Kirsch, who runs Blonde Bronzed Twentysomething and routinely coaches single people and couples about their relationships, said studies show that relationships don’t always work out for people who have the same birth order.

“We are used to what we know and we tend to chose partners who complement us – not who are just like us,” Kirsch said.

"When we’re growing up, we learn how to cope, how to be in a relationship. If you’re the baby in the family, you’re used to being treated a specific way. ”

Birth order also has an impact on your personality traits, and your career.
