There must be something in the royal water; 2018 is a huge year for monarchies around the world.

According to the Office of the Marshal of the Realm, Princess Madeleine of Sweden gave birth to a baby girl on March 9 at 12:41 a.m. Madeleine and her husband Christopher O'Neill welcomed their new child at the Danderyd Hospital and both mother and baby are in good health.

According to E!, the baby weighed 3465 grams (approximately 7.6 pounds) and measured at 50 centimeters long. The princess's first (unofficial) royal portrait, posted to Instagram, showed off the new bundle dressed in a prim pink cardigan, white knit pants, and a ruffle neck collar. They have yet to announce a name for the princess. "We are thrilled about the new addition to our family," the new father of two said in a statement, according to E!. "Leonore and Nicolas are looking very much forward to finally meeting their new little sister." The couple also have a 4-year-old daughter, Princess Leonore, and a 2-year-old son, Prince Nicolas.

In just a month, Kate Middleton and Prince William will welcome their own royal bundle of joy, making Princess Charlotte, 2, an older sister for the first time and adding to their family of four. Wills and Kate have thus far stayed mum about the sex of their third child, but hopefully the new addition will join Charlotte and George as an honorary flower girl or pageboy at Prince Harry and Meghan Markle's May 19 wedding.
