The baby was born at 5:26 a.m. local time, according to Buckingham Palace. He weighed 7 pounds, 3 ounces and is seventh in line to the British throne. Harry was at Meghan's side and both mom and baby are "doing well," the palace said in a statement.

The prince, now a first-time father, said he's "just over the moon."

We’re taking a look at some of the most adorable moments of a young Duke of Sussex. Who knows? Maybe they’ll give us a glimpse into the new royal's childhood!

A well-traveled baby

His mother's son

Princess Diana was always open about how it was important for her to teach her sons about love and respect. The connection she shared with Prince Harry is undeniable in pictures like this.

A friend to animals

Not only was Prince Harry a sweet child to people he met, but he was also extremely loving to the animals in his life. Let's be honest, Prince Harry trying to cuddle this dog is all of us when we see a puppy.

Always the happiest kid

A well-behaved prince

Prince Harry was very close to his mother, Princess Diana, and always followed her lead. He stood quietly by the Princess of Wales as she inspected the troops.

It's so crazy to think that the royal family's sweet, funny, redheaded boy in these pictures is now a first-time father to his own boy!
