Prince Carl Philip and Princess Sofia pose for first family portraits with newborn Prince Alexander

Prince Alexander stars in five new portraits released by the Swedish royal palace. The baby boy, the family's newest member born on April 19, stars alongside his proud parents Prince Carl Philip and Princess Sofia.

In one photo, taken at the family's home in Drottningholm Palace, new mum Sofia is glowing with happiness. The former model cradles her son in her arms and beams down at him, while her husband Carl Philip rests an affectionate hand on his baby's head.

The new parents, who married in June 2015, are no doubt floating on cloud nine. It's been just over three weeks since they welcomed their baby boy and the expressions on their faces reflect pure delight.

The photos were released to mark Carl Philip's 37th birthday

Prince Alexander Erik Hubertus Bertil, Duke of Sodermanland, was born at 6:25 pm at the Danderyd hospital in Stockholm and weighed about 7 pounds 9 ounces.

The first official portrait of Alexander was taken by his dad Carl Philip and released a few days after the birth. The little boy was pictured asleep in his cot, swaddled in blankets.

Fans had previously been given a glimpse at the new royal when a picture of the family leaving hospital was released the day after the birth.
