Princess Mary wants normal childhood for her kids

Denmark's Princess Mary and Crown Prince Frederik want their children to have a "normal" upbringing.

The couple added twins to their family - which already includes Prince Christian, five, and Princess Isabella, three - when Mary gave birth to a boy and girl almost two weeks ago and friends say the royals are determined their children will have a regular childhood.

Ulrik Ulriksen, the prince's former classmate and royal expert, told Australia's Herald Sun: "Frederik and Mary have said they are modern people and they want their children to have a normal upbringing and have a fun childhood as normal as it possibly could be."

When taking the twins and his wife home from Copenhagen's Riget Hospital earlier this week, Prince Frederik, 42, said: "We just want to find a rhythm and get comfortable with normal life at home."

University of Copenhagen's associate professor of Danish history Jes Fabricius Moller added Mary and Frederik "give the impression of having a very normal life".

He said: "They have protected their children from the public eye. That is a sign of normality."

Frederik, has taken three weeks paternity leave to be with his family, while his 38-year-old wife will announce the names of the twins at their Christening in three months time.
