Meghan Markle and Prince Harry were determined to do things their own way when it came to welcoming their first child.
And they did just that, breaking many of royal traditions as they announced the birth of their baby boy.
They said they wanted to celebrate privately as a family before introducing their newborn to the world - a decision which split opinion.
Despite not having that special 'first picture' of Baby Sussex, there are lots of things we already know about him.
We know he was born on Monday, May 6 at 5.26am weighing 3.2kgs (7lbs 3oz).
We know Meghan's mum Doria Ragland is with the couple at Frogmore Cottage, and that the Queen, Charles, Camilla and other members of the Royal Family are "delighted".
But there are a few things the couple haven't announced yet.
What the baby is called
According to Harry, the couple are yet to decide on a name for their son.
Speaking yesterday afternoon he said: "The baby was a little bit overdue so we've had a little bit of time to think about [a name].
"That's the next bit."
Who the medical team were
When the Duchess of Cambridge welcomed Prince George, Princess Charlotte and Prince Louis, the notice posted on the easel outside Buckingham Palace was signed by the medical team who delivered the baby.
However this was not on Meghan and Harry's notice.
It simply read: "The Queen and the Royal Family are delighted at the news that her Royal Highness The Duchess of Sussex was safely delivered of a son at 0526 today. Her Royal Highness and her child are both doing well.”
If Meghan has spoken to her dad
We don't yet know if Meghan has spoken to her dad about his new grandson.
Thomas Markle, 74, released a statement this afternoon saying: “I'm delighted to hear that mother and child are doing well.
“I am proud that my new grandson is born into the British royal family and I am sure that he will grow up to serve the crown and the people of Britain with grace, dignity, and honour.
“God bless the child and I wish him health and happiness, and my congratulations to my lovely daughter Duchess Meghan and Prince Harry, and God save the Queen.”
Meghan reportedly hasn't spoken to her dad in months, and he has given several interviews about their fall out.
How long Meghan's labour lasted
Shortly before the birth was announced, Buckingham Palace confirmed that Meghan went into labour yesterday morning.
The statement read: "The Duchess went into labour in the early hours of this morning.
"The Duke of Sussex was by Her Royal Highness' side. An announcement will be made soon."
However, we don't know exactly how long she was in labour for.
What the baby looks like
Unlike Kate and Princess Diana, Meghan didn't pose for photos after giving birth.
This means we haven't seen what Baby Sussex looks like.
They couple will invite selected members of the media to a small photocall in the next few days, which is when we'll get our first glimpse of the little royal.
Which royals have met Baby Sussex
The Queen, Prince Charles, Camilla and other members of the Royal Family are said to be "delighted" at the news.
However we don't know if any of them have actually had the chance to meet Baby Sussex yet.
The Queen is currently staying just a few minutes away from Frogmore Cottage at Windsor Castle, so there's a chance she might have popped in to meet her new great-grandchild.
Meghan's mum Doria is staying with the couple and could have even been present for the birth, so Baby Sussex would have already met at least one grandparent already.
However we don't know if Charles, Camilla, Kate, William and the Cambridge kids have popped over yet.
