On Monday, Kate Middleton, the Duchess of Cambridge, and her husband Prince William welcomed their third child, a boy, into the world.

Though little is known about the newest member of the royal family, including his name, William did give the world at least one update: He’s behaving like a good royal son should.

On Wednesday, Prince William attended an Anzac Day Service of Commemoration and Thanksgiving at Westminster Abbey alongside his brother Prince Harry and future sister-in-law Meghan Markle. And though everyone is certainly excited about the upcoming royal wedding, all anyone wanted to discuss was the new baby. When asked by well-wishers how his new child is fairing, William reportedly replied, “Very well, thanks.”

According to People, William added that everyone, including his wife, is “in good form, luckily” and added that the new baby is sleeping, which is “going reasonably well so far, so he’s behaving himself which is good.”

Though perhaps the baby is sleeping because his first few days of life have been nothing short of a whirlwind. Kate, who gave birth at 11:01 a.m. to the 8-lb. and 7-oz. baby, shared him with the world just seven hours later by stepping outside of St. Mary’s Hospital for photos.

Not long before that, the new baby was introduced to his older brother and sister, Prince George and Princess Charlotte. He was then whisked away to his new home at Kensington Palace, where he’ll undoubtedly be doted on by his parents, uncle, grandparents, and great-grandparents, Queen Elizabeth and Prince Philip.

“It completes them,” royal biographer Ingrid Seward told People in this week’s cover story. A friend close to William and Kate added that Kate “is one of three siblings, and it’s a good family size. Boy-girl-boy is pretty cool as well.” Truly, it is a royal fairytale ending.
