"I haven't been in many births. This is definitely my first birth," he added. "But it was amazing. Absolutely incredible. And, as I said, I'm so incredibly proud of my wife. And, as every father and parent would ever say, your baby's absolutely amazing, but this little thing is absolutely to die for. So I'm just over the moon."
He said that both the baby – whose name is yet to be revealed – and Meghan are doing "incredibly well".
The 34-year-old also described his admiration for women's strength in the act of childbirth.
"How any woman does what they do is beyond comprehension," Harry said. "We're both absolutely thrilled and so grateful for all the love and support from everybody out there. It's been amazing."
