Prince Harry and Meghan, Duchess of Sussex, showed off their newborn baby boy to the public on Wednesday before introducing him to Queen Elizabeth II at Windsor Castle.

The couple said they were about to visit 93-year-old Queen Elizabeth, the world’s longest-reigning monarch, at the castle to allow her to meet her eighth great-grandchild, who is seventh in line to the throne, CBC News reports.

“It’s magic — it’s pretty amazing, and I have the two best guys in the world, so I am really happy,” Meghan said when asked what it’s like to be a new mother.

Their son was born early Monday morning, weighing seven pounds, three ounces.

After the baby’s arrival, Harry had told reporters he was “over the moon” about his new son, noting “mother and baby are doing incredibly well.”

“It’s been the most amazing experience I can ever possibly imagine,” a visibly overjoyed Harry said. “How any woman does what they do is beyond comprehension, but we’re both absolutely thrilled.”
