Today saw the birth of an as-yet-unnamed son to Prince William, HRH the Duke of Cambridge, and Catherine, the Duchess of Cambridge. The newest addition to the British royal family is now third in line to the throne, behind his father, Prince William, and his father, Charles, Prince of Wales.
Officially, the child is to be known as His Royal Highness Prince of Cambridge.
The British Royal family, and the newborn's parents in particular, are no strangers to the world of record-breaking - Queen Elizaebth II is the longest-reigning living monarch, and it was the marriage of Prince WIlliam to Catherine in 2011 that set a new mark for the most live streams of a single event - with 72 million views from 188 countries on The Royal Channel on YouTube alone.
But, today is all about the newest, littlest royal, whose name we may not officially know for as long as up to 10 days. So, what records might he set?
With his father standing at 1.91 m (6 ft 3 in) in height, it may not be a surprise if he grows up to become the tallest crown prince - the current record being held by 1.97 m (6 ft 5.52 in) heir to the Spanish throne, Príncipe de Asturias, Don Felipe de Borbón y Grecia.
In the more immediate future though, there is a chance the royal son will be christened in the Royal Christening Robe, which holds the record for the most babies christened in the same robe. First used in 1841, it has been worn by over 70 royal babies, including Prince William himself a generation ago. Although the Queen commissioned a replica be created in 2004 to preserve the original, could it be brought out of retirement for this exceptionally special child?
It's likely the little prince will be inundated with gifts from across the globe, from baby clothes to toys and teddy bears - so perhaps the latter can be gathered together for a record? The largest gathering of plush toys in 2008 consisted of 5,884 teddies and other fluffy toys, achieved by the Girl Scouts of Southeast Florida (USA).
Of course, the royal baby will go through plenty of diapers (nappies) in his early years, though it is highly unlikely they will be used to create a new largest diaper sculpture - the current record holder measured 5.14 m (16 ft 10 in) tall and 13.2 m (43 ft 4 in) in diameter, created by Huggies in Buenos Aires, Argentina.
It's also unlikely he will need one of this size - the largest disposable nappy measures 3.10 m (10 ft 2.05 in) long and 2.50 m (8 ft 2.4 in) wide!
Finally, every baby needs to drink lots of milk to grow up strong and healthy - though it may be quite some time before the prince comes close to challenging either Peter Dowdeswell's fastest time to drink two pints of milk record (3.2 sec), or Noor Abdulrahmon Alzaben's fastest time to drink 250ml using a baby bottle ( 54.38 sec)!
Congratulations and best wishes to the Duke and Duchess of Cambridge, and of course the newborn royal, from all of us here at Guinness World Records. It will surely only be a few short years until he is reading a Guinness World Records book of his own, and maybe even with a record he holds in it!
