Princess Sofia & Prince Carl Philip's Eldest Son Prince Alexander Of Sweden Turns 5! See The Adorable New Portraits

He's growing up so fast! Princess Sofia of Sweden and Prince Carl Philip's eldest son, Prince Alexander of Sweden, turned five on Monday, April 19, and the parents couldn't help but share a new portrait of him via social media.

"Today we celebrate our charming, curious and mischievous 5-year-old," the pair captioned two new photos of their birthday boy on Instagram.

Of course, people sent their well-wishes to the young prince. One person wrote, "Happy Birthday Prince Alexander," while another added, "Happy birthday dear Prince Alexander. I hope this day is as awesome as you are." 

A third user added, "What a cutie. Happy birthday x." 

Princess Sofia, 36, and Prince Carl Philip, 41, recently welcomed their third child — a baby boy named Julian — on March 26.

A few days later, the duo shared new photos of their brood — one of their newborn son, Julian, and one of her four boys. 

"Life gave me not only one but four beautiful princes ?? A sincere Thank you for the warm congratulations in connection with Julian’s birth," Princess Sofia captioned the sweet snap.
