Secondly, the Royal has a huge range of resources available to her and her new son.
The name of the new prince has not yet been announced but the family have returned home to Kensington Palace. Just hours after giving birth she had hair that was immaculately blow dried, makeup that was just the right kind of dewy and she was wearing heels.
Kate Middleton and Prince William's newborn son arrived on Monday, and he is heavier than either of his siblings were before him. "Congrats on baby number 3!" tweeted Jenna Hardy.
When William brought his children to see their brother, Princess Charlotte, 2, turned and waved at the gathering of well-wishers. Television news helicopters followed the royal Range Rover as it made the mile-long (1.6 kilometer) journey to the family's Kensington Palace residence.
So how does she do it?
This rule is not followed as strictly as the others, though, according to The Sun.
The other side of acute morning sickness?
Bookmakers have seen a flurry of bets placed on William and Kate's infant boy being given the moniker of the famous leader of the Knights of the Round Table. The newborn prince was wrapped in a white shawl while being presented to the crowd. "I'm not saying it's going to change anything, but at least we will know that we tried".
"The monarchy is about births, deaths and marriages and these events remind us how this system works and highlights again the inequality of those born into royalty and those born into poverty".
Third time's a charm. Who could ever say that she gave birth earlier that day? "She was the epitome of the ideal pregnant woman as far as taking care of herself, and that's a huge factor".
We're not sure if this is just a coincidence or not, but both women looked handsome hours after giving birth.
Natasha Archer, Kate's stylist, was spotted by the media mob outside the hospital just before Kate came out.
She paid a tribute to her late mother-in-law, Princess Diana, with the choice of her outfit.
